Surprisingly to many, the true reliability and lifetime of light‐emitting diode (LED) lighting systems is currently unknown. Even worse, lumen maintenance values of LED devices are widely used as a proxy for the lifetime of an LED lighting system, which is misleading since light degradation or lumen maintenance is but one component of the reliability of a luminaire. For many manufacturers this approach cannot simply be ascribed to overly ambitious marketing efforts, but rather to dependence on anecdotal numbers in the absence of real data. In addition, we can impute simple ignorance in taking specifications at face value which may or may not live up to claims. It isn't just about the LED. Good LEDs can be incorporated into poorly engineered products and turn the Methuselah of lighting into the exponent of “live fast, die young.” The promise of LED lifetime is often presented in terms of hours and years but with little background data to support anything beyond vacuous promises. The statement of 100,000 hours of LED luminaire lifetime has given way to the realization that there is little consistency, very little published data, and few hard facts around so‐called luminaire lifetime numbers. The situation is better at the LED package level, where reputable manufacturers have thousands of hours of data under varying conditions.
But this is not enough. To manufacturers and specifiers in the solid‐state lighting (SSL) community, the dawning realization is that we need to work together towards understanding the issues surrounding true lifetime and reliability. We need to begin by cataloguing such failures and developing good models for underlying failure mechanisms. This process of understanding and explanation is very common in technological progress. Steam engines existed long before deep understanding of thermodynamic processes. With LEDs, we have a substantial head‐start on the underlying physics and many years of experience in both lighting and semi‐conductors as well as reliability of related products. There is no reason not to begin this journey and every reason to start. We will figure this out, find reliability methods and metrics, and learn the underlying root causes of failure. But without data, experiments and models, it is all conjecture. We need a program to drive to reliability metrics.
This guide is a set of recommendations for reporting and demonstrating reliability in terms of luminaire product lifetime. These recommendations have been developed by a working group under the U.S. Department of Energy Solid State Lighting program. This group is under the guidance of the SSL Quality Advocates oversight committee, a joint body of DOE and the Next Generation Lighting Industry Alliance (NGLIA). The reliability and lifetime working group is composed of members of the NGLIA as well as other experts in reliability, lighting, and LED technology. As such, this guide is not an accepted international standard. Rather, it is meant to provide standards bodies with recommendations for their work in supporting the needs of the SSL community. These standards organizations will ultimately determine the details of the methods to measure and report the reliability of SSL luminaire products.

Modern learning and teaching is more personalised and diverse, resulting in pupils learning in a variety of spaces and in various ways. A dining area, for example, may be used for group discussion or individual reading; a circulation area, such as part of an atrium, could be used for informal tutoring or project work; and laptops could be used everywhere. It is important to find out in the early stages of briefing and design how spaces will be used by the school so that lighting flexibility is designed in.
In most types of buildings, users prefer rooms to have a day lit appearance during daytime hours. In schools, natural lighting during daylight hours should always be the main light source for reasons of quality of light and sustainability. Electric lighting and natural lighting should be complementary. Electric lighting will take over during the hours of darkness and should supplement natural lighting when it fades. To make sure that running costs and maintenance are reduced to minimum, light sources, luminaires and lighting controls need to be highly efficient, with a long life.
Pupils like spaces that are interesting and unique. They enjoy learning in them even though lighting conditions may not be ideal. There is a place for imaginative lighting environments in schools and this publication aims to encourage creativity, not create blandness or uniformity.
Health and safety
Learning and teaching rely upon good lighting. Although poor lighting is easily identified in use, it is often overlooked at the design stage. Our eyesight is resilient, so we may be unaware of the problems caused by poor lighting in our schools. Yet it can result in slower reading, poor posture, diminished concentration and long-term weakened vision. Lighting in schools is required not only for general safety but also for visual tasks. The two main issues to guard against are glare and flicker.
Glare
Glare is a common problem in the classroom. It occurs when a bright image (which is not the object one is trying to see) is seen either directly or by reflected light. This can cause significant difficulty with visual tasks. Although pupils try to compensate for glare by turning their heads or squinting, glare causes eyestrain and headaches and can sometimes be disabling. It can also cause loss of concentration and reduced productivity.
Glare can be divided into two types:
• Discomfort glare is not necessarily detrimental to vision but it produces feelings of visual discomfort.
• Disability glare occurs when a bright light source is close to the line of vision and makes the task more difficult to see. This problem is controlled by assessing the lighting installation in terms of its glare rating and ensuring that it does not exceed the recommended maximum.
Glare can be minimised by:
• The correct choice, orientation and positioning of the room furniture
• The use of internal or external blinds, which can reduce problems caused by excessive sunlight or daylight
• The use of louvers on fluorescent luminaires and/or the use of indirect lighting solutions, which will help reduce direct vision of the light source and therefore the instance of glare
• Correct choice of computer screen with anti-glare filters if necessary, together with orientation to avoid sunlight and daylight reflection
• Careful design of the luminance of the whiteboard relative both to sunlight and daylight glare and glare from luminaires.
Flicker
Flicker can cause discomfort or annoyance to some people. It can also produce stroboscopic effects with moving objects, which can be dangerous. For example, rotating machinery in a workshop can appear to be stationary. Epilepsy can be triggered by low frequency flashes of light, which can occur with some compact fluorescent lamps at ignition, or with discharge lamps towards the end of their life. Problems relating to balance, and some brain disorders, can also be exacerbated. All these can be avoided by using high frequency control gear.
Disability issues
Good quality lighting is important to help pupils learn, especially those with special educational needs (SEN) and/or any disability. Natural lighting with additional artificial light should be used where necessary, avoiding glare and revealing good visual contrast and colour rendering. Light levels should be adequate on the working plane and for people to clearly see the teacher’s face, the whiteboard and computers without creating reflections, shadows and harsh contrasts. For an even better effect, light sources should not be visible, flicker should be avoided and up-lighters should be used.
Hearing impaired people need to be able to see lip movements clearly, so the correct lighting level and direction are crucial. For example, if light is directed too much in a downward direction, it will produce harsh shadows, which will make lip reading difficult. The design of specialist accommodation for pupils with SEN and/or any disability is beyond the scope of this document and specialist advice should be sought. However, there are relevant design issues that should be considered for all schools:
• The colour rendering of the light source and the extent of contrast are particularly important. Some visual impairment involves a degree of colour blindness and it is important that contrast of tone as well as colour should be produced on the objects illuminated.
• Careful use of colour can help pupils recognise and identify objects. For instance, using a darker colour for a door frame (contrasting with door leaf and wall) will help in locating the door. A handle that clearly contrasts with the surface of the door and is non-reflective will also make it easier to distinguish.
• Students with visual impairment often require higher than normal levels of illuminance. It is not necessary to install this as a feature of the primary lighting system but provision should be available for supplementary task lighting.
Energy efficiency
The energy efficiency of artificial lighting depends on:
• The penetration of natural lighting indoors – if there is good daylight distribution in the classroom and good daylight levels, artificial lighting may not be required
• The luminaire efficiency and its electrical components, lamps and control gear
• The successful specification of the lighting controls, eg, their usability and response to changing conditions
• The operation, cleaning and maintenance regime.

Whether tenants or building owners, today’s leading companies are no longer content with “facilities as usual.” Instead, the office environment is seen as a strategic asset, a flexible platform for meeting rapidly changing workflows and competitive needs. It’s a tool for boosting collaboration and communication. To make today’s office facilities as responsive, productive and attractive as possible, it’s important to adapt the spaces to the occupants’ ever-changing demands. In creating an office environment that fills those needs, you create higher value and return. New lighting technologies are helping to reshape the office environment. More efficient, more adaptable, and more sustainable lighting solutions support the varied settings for working and meeting. Understanding what moves a company’s bottom line is essential to selecting your office lighting systems.
To be a leader in today’s competitive environment, property owners and facility executives need to understand the importance of ambiance, well-being, and sustainability. Lighting can support these three key factors to help address the critical issues of productivity, corporate image, and bottom-line profitability— helping you to transform your facility in meaningful and innovative ways.
Today’s business workplace must be responsive, productive, sustainable, and profitable. New choices in lighting design can help drive solutions to the issues facing facility executives.
• Productivity: Enhance occupant motivation and increase productivity
• Brand Image: Impress visitors and attract tenants and customers
• Profitability: Control facility operational costs and overhead well-being productivity ambiance brand image profitability sustainability
Choosing the right office lighting solutions can help you achieve the desired mix of ambiance, well-being and sustainability.
Ambiance: Welcoming, inviting facilities can motivate occupants and engage visitors. Effective, well-illuminated environments can positively impact employee productivity and support your brand and mission.

Philips is committed to innovative solutions for reducing a facility’s environmental ‘footprint’ and cutting energy use—while remaining cost-effective.
Lighting the Path to Productivity
New office environments are emerging to address today’s rapidly changing work styles and business approaches. For facility executives, this means facing critical social issues and advanced technologies—while remaining focused on maximizing building performance. Occupants and tenants spend a large portion of their days in the office, and are demanding better working environments that can spur innovation and boost productivity.
Lighting can make a space desirable not only by enhancing the visual environment, but by making a space more flexible. Lighting systems should adapt to occupant needs for team space, open floor plans and offices. With shorter lease terms, tenants may change, but the lighting system doesn’t have to. Philips lighting solutions can help transform ordinary buildings into high-performance facilities.
Creating a Positive Image
Facilities speak to who you are—and where you’re going. More than ever, business owners view their workplace as a competitive tool not only for boosting efficiency but also for recruiting new talent and winning new business. So in today’s competitive marketplace, first impressions count. Facility executives can set the tone with efficient general lighting, and set themselves apart with architectural and accent lighting, presenting the corporate brand image of a true leader.
Managing Costs and Increasing Profitability
In today’s economy, commercial facilities need to do everything they can to reduce overhead. Facility executives face spiralling occupancy costs on the one hand, and directives to boost margins on the other. Choosing the right combination of components and designing a system properly cuts operational expenses and enhances the overall contribution occupants make to an organization’s bottom line. Simplification—along with energy-efficient lighting solutions—means savings.
Replacing outdated lighting systems with more efficient, environmentally friendly solutions will reduce energy consumption and maintenance requirements. Working with fewer lamp types and standardizing wattages can reduce complexity, making maintenance more manageable and less costly. Philips has a strong commitment to sustainability, continuously finding innovative ways to deliver more environmentally sound and energy-efficient choices. We are convinced that those facilities that combine the principles of economic growth and environmental stewardship will be the winners in the future. To help you realize your potential savings, our team of lighting experts can perform a Lighting Audit to help you maximize your profits without sacrificing the occupant’s experience.

From the seasoned business traveller to families on vacation, today’s hotel guests are well-versed in the range of lodging options available in the marketplace. Before they arrive for check-in, they check out amenities and services, and comparison shop for lodging in virtually any destination. Whether working away from home or planning an exotic getaway, guests seek properties that measure up to cultivated lifestyle expectations.
Hospitality is About Experiences
Hospitality is all about creating memorable travel experiences, with top-tier services and surroundings that win guest loyalty. Good lighting is a key component in creating those surroundings. From the welcoming atmosphere of a lobby to flexible guest room lighting to the subdued glow of an intimate restaurant, the right light creates a backdrop for a pleasant stay. Yet poor lighting can be a common guest complaint. To keep them coming back, it’s crucial to get lighting right the first time—and make it easy to maintain. For more than 100 years Philips has been providing products uniquely suited to improving the hospitality environment—from televisions to energy efficient lighting solutions. Let our expertise in hospitality help you create spaces that delight.
To be a leader in today’s competitive marketplace, hoteliers need to focus on the importance of ambiance, well-being and sustainability to address the critical issues of the guest experience, the brand and to meet your financial goals. Lighting can support these three key factors and help you transform your property in meaningful and innovative ways.
Ambiance: Welcoming and inviting spaces can engage guests in a variety of activities. The use of lighting solutions to enrich their surroundings can elevate guests’ moods and set the scene for a memorable hotel stay.
Well-Being: Comfortable, well-balanced spaces support the physical and emotional comfort of your guests. Efficient, well-balanced lighting systems can improve the guest experience and boost your bottom line.
Sustainability: Employing systems that reduce a property’s environmental impact builds a positive image, enhances guest relations, and saves dollars on energy use and maintenance. Today’s guests are conscious of the environment and care about how you operate your property—they want to know who you are as much as what you have to offer. Our lighting products offer some of the highest efficiencies and longest life of any available today. Philips is committed to innovative solutions for reducing a hotel’s environmental “footprint” and reducing energy use—while remaining cost-effective.
Choosing the right lighting solution can help you achieve the desired mix of ambiance, well-being and sustainability.
Ensure that each guest’s first impression is a positive one. Lighting serves as the backdrop for creating that memorable initial experience. It sets the scene for a successful hotel stay, and helps reinforce the intent of varied settings. Outdoors, architectural lighting can turn the hotel into a prominent landmark. Inside, the use of accent, or focal lighting can highlight signature elements, creating an inviting atmosphere and distinguishing your property from the competition. Scene-setting lighting design and colourful accents in the lobby communicate “you are welcome” to arriving guests. At the reception desk, bright light provides confidence and orientation. In guest rooms, flexible lighting scenes offer the option of bright, task light—or diffused, restful light—to provide your guests with an experience that meets their individual needs.
Making guests feel comfortable starts by allowing them to move freely within a visually appealing environment. Well-lit surroundings can improve comfort and confidence levels. At every turn, guests should feel confident and find opportunities to make a space their own. Flexible lighting enables guests and staff to adjust each environment to suit varied tasks. In offices and conference rooms, efficient, flexible lighting can adjust to varying working conditions to boost concentration and motivation; in the guest room, energizing and relaxing light can help the body adjust and increase comfort levels. In bathrooms, bright light revitalizes while presenting a hygienic impression.
Branding and Company Responsibility
As today’s hospitality climate continues to change with a focus on environmentally responsible initiatives, choosing sustainable lighting solutions for your properties can build brand loyalty among guests. Consumers increasingly make purchase decisions based on an organization’s environmental stewardship. Investing in Philips energy-efficient lamps, ballasts and systems that reduce your property’s environmental impact can pay dividends worth even more than the energy savings. Such investment can earn respect from customers and their willingness to become repeat guests.
Reducing Operating Costs
Because hotels operate 24-7, even small gains in efficiency can lead to significant savings. Replacing outdated lighting systems with more efficient, environmentally friendly solutions will reduce energy consumption and disposal costs. Selecting lighting components that perform better over time also means fewer lamp replacements and disruptions to hotel operations. Working with fewer lamp types and standardizing wattages can reduce complexity, making maintenance more manageable and less costly.
Reducing operating costs through the installation of energy efficient solutions can be measured using financial metrics like revenue per available room (RevPAR) or average daily room rate (ADR).
As noted by Energy Star, “On average, America’s 47,000 hotels spend $2,196 per available room each year on energy. This represents about 6 percent of all operating costs. Through a strategic approach to energy efficiency, a 10 percent reduction in energy consumption would have the same financial effect as increasing the average daily room rate (ADR) by $0.62 in limited-service hotels and by $1.35 in full-service hotels.”1
Hospitality T.C.O.: The Total Cost of (Lighting) Ownership
Understanding how various lighting choices impact the bottom line is essential. These elements will affect a property’s payback, cash outlays and return on investment. Taken together, it’s the total cost of ownership, or T.C.O.
Four factors drive the total cost of lighting ownership:
Normal 0 false false false EN-NZ X-NONE X-NONE MicrosoftInternetExplorer4
Street Light Costs
Converting HPS, MH, mercury vapor, or incandescent street lights to LEDs incurs a capital cost, but this can be recouped over the lifetime of the lights. LEDs have an estimated lifetime five times longer than conventional HPS or MH lamps, and energy savings of 35% or more. These efficiencies mean that payback periods for LED street lights can currently be as low as 4.4 years (Ann Arbor, no date). Because the entire street luminaire (see below), not just the lamp, is typically replaced when converting conventional street lights to LED street lights, jurisdictions may reduce installation time and avoid warranty issues. More expensive LED street lighting systems include dimmers or motion sensors, but can dramatically decrease costs by reducing energy consumption and maintenance costs even further.
Cost
Although LED's typically have a much higher purchase price, they are far more energy-efficient and longer lasting than their conventional counterparts which leads to lower total costs when factoring in electricity savings and reduced maintenance and disposal costs.
Exit Sign Costs
Currently, LED’s are far more cost efficient than incandescent and fluorescents. They are available in the a variety of styles (including stencil, matrix and edge-lit models) and price levels. In the short term, it may be cheaper to continue using incandescent bulbs in existing incandescent-lit exit signs. However, it is more cost-effective to replace existing incandescent and fluorescent-lit exit signs with new LED exit signs or to upgrade them using an LED retrofit kit.
Energy and Global Warming
Incandescent exit signs typically contain two 15- or 20-watt bulbs that draw 30-40 watts in total, whereas LED exit signs consume as little as less than one watt and no more than 10 watts. Since exit signs are lit all year around, 24 hours per day, each LED exit sign retrofit can save about 300kwh, preventing the release of half a ton of CO2 annually. Replacing incandescent-lit exit signs with new LED signs or retrofitting existing signs to use LED lamps is one of the easiest and most cost effective energy e3fficiency retrofits available to public and commercial facilities. Fluorescent lamps are another common bulb used in exit lighting, and although more efficient than its incandescent counterpart, they still use up to 10 times more energy than LED exit signs.
Hazardous Substances, Health and Safety
Incandescent signs, which contain lamps that typically have a rated life of 500 to 5000 hours, are likely to become partially or fully unlit more often than LED exit signs, creating safety hazards for building occupants during emergencies, and risking fines by fire marshals. Frequent bulb changing poses occupational risks for workers who must climb ladders to remove fragile glass bulbs that may contain lead solder in their bases. Lead is a known neurotoxin and causes learning and developmental disabilities. Fluorescent lamps used to light exit signs generally have a rated life of 5000 to 10000 hours, which is longer than most incandescent lamps but still far shorter than LED’s, which can last 25 years or more. Replacing fluorescent lamps can expose workers and occupants to mercury, a persistent and bio-accumulative toxic chemical known to cause damage to the brain, nervous system and heart of humans and animals. Mercury can be released during lamp manufacture, storage, transportation, installation, recycling or disposal.
End of Life Management
A typical incandescent exit sign bulb lasts just 500-5000 hours (about 1 – 6 months) and must be replaced about twice per year. In comparison, red and green LED exit sign lamps typically have a rated life of 50,000 to 200,000 hours (6 – 25 years, and some with a 25 year warranty). At the very minimum, 10 incandescent bulbs are disposed of for every one LED required to light the same exit sign.
Citizens in Raleigh, N.C. express feeling safer in municipal structures that have switched to LED lighting, according to a new survey conducted by Mindwave Research. With the results
of this survey, the "LED City" initiative in Raleigh has proven to have benefits beyond energy efficiency.
The survey asked 200 people about their perceptions of safety and other aspects of a municipal garage in Raleigh. Both men and women expressed feeling significantly safer after the installation of LED fixtures: the number of respondents who rated the garage as "very safe" increased by 76% after the LED fixtures were installed. "LED technology provides a clear benefit to municipal infrastructure, as well as to the citizens it serves," said Charles Meeker, mayor of Raleigh, "This survey shows that LEDs can do more than improve light quality. In addition to the proven environmental and energy efficiency benefits the city has already documented, the survey shows that LEDs' bright white light can help improve public feelings of safety in city spaces." The survey also measured respondents' ratings of lighting quality and cleanliness in the municipal garage. After the installation of LED lighting, 86% of respondents rated the lighting quality of the garage as "excellent" -- a 258% increase over pre-installation responses. Seventy-six percent of respondents rated the cleanliness of the parking facility as "excellent" after LED installation versus 58% before the LEDs were installed.
In the coming year, Raleigh plans to continue its "LED City" initiative by creating a "living laboratory" of LED light use throughout the city, including pedestrian and walkway lighting. The purpose of the initiative is to evaluate energy-efficient infrastructures. The announcement of the initiative was hailed by Kateri Callahan, president of the Washington, D.C.-based Alliance to Save Energy (ASE) as "a milestone toward large-scale adoption of clean, energy-efficient technologies." Callahan stated, "Raleigh's progressive commitment to becoming the first 'LED City' will no doubt serve as a model for other cities seeking to improve energy consumption and reduce negative impacts on the environment."
New generation LED lights offer significant safety advantages to parking lots, buildings, and other city infrastructure ... they're cleaner, greener, and last for over a decade, so they produce less landfill and contain none of the mercury found in fluorescent lighting.
BRICK IN THE WALL originate from the world of decoration where the founder Frank Verschuere has noticed the demand for seamless integrated light. One of the first luminaires they experimented was the "Normall", a plaster fitting with a minimalistic design. The possibility to paint the luminaires in the same color as the wall was an added value for his company of decoration. Due to the great success and acceptance of these fittings by quite some architects , Frank Verschuere decided in 2008 to join several Trade Shows as "Hospitality & Design Show"(Las Vegas 2008),"Nordic Building & Construction" (Stockholm 2008). A special range of plaster fittings with a Moorish architecture, were designed for the "index" Trade Show in December 2008 in Dubai.
In 2008, Brick in the wall started collaborating with the lighting design company CEE-ID to develop a complete new collection called "Spring 2009". The basic idea of this collection is to create unexpected and inspiring plaster fittings with light and shape as a true amalgam with the architecture. The first introduction took place at A@work in Kortrijk (Belgium). In May 2009, Brick in the wall moved to a new and larger facility in Waregem (Belgium) close to the E17 highway. Today, Brick in the wall is an international lighting company that offers a complete range of residential, commercial and even custom-made lighting products that can be seamlessly integrated in any office, hotel, or store. Innovative lighting designed to fit and enhance any environment, ranging from architecture all the way to residential lighting.

The large atrium at the Art Gallery has many functions: as an entrance to the gallery, a reception area, a meeting place, an entertainment area, a display opportunity and a showcase for the interior of the sculpture wall.
As such, it is important that the lighting in the area is clear, high in intensity, neutral in colour and able to operate for long periods with minimal maintenance.
The lighting initially installed in the atrium was 300 and 500 Watt halogen lamps, with a rated life of 4000 hours. The lights functioned well, but the relatively short life span of the lamps was problematic as a cherry picker is required to access the high ceiling areas. The lights also added approximately 45 kilowatts of heat to the area, the equivalent of 22 kilowatt bar radiant heaters.
The power demand of these lamps was also a consideration, with power requirements of:
| 6 lamps | X 500 Watts | =3000 Watts |
| 53 lamps | X 500 Watts | =26,500 Watts |
| 52 lamps | X 300 Watts | =15,600 Watts |
| Power requirement for previous atrium lighting | 45,100 Watts (45.1 kW) | |
| (There was some additional power required for the ballasts) | ||
Technology has moved on quickly since the first commissioning of the Art Gallery in 2002, so that in November 2008 light fittings were installed that improve many of the operating parameters of the previous lighting, including life span, heat production, maintenance, lumens emitted and power required.
The power demand of the new lamps is as follows:
| 6 lamps | X 150 Watts | =900 Watts |
| 53 lamps | X 84 Watts | =4 452 Watts |
| 52 lamps | X 8 Watts | =416 Watts |
| Power requirement for present atrium lighting | 5768 Watts (5.768 kW) | |
| (There is some additional power required for the ballasts) | ||
The upgrading of the lighting has reduced the energy requirement of the lighting by 39 kilowatts or approximately 140,000 kilowatts or $15,000 a year.
There are additional benefits to the change, including:
General info on Mode 3Mode 3 is a special mode and can only be activated by means of the advanced mode selection tool (IRT 8099/00). The sequence is to push the "mode" button and push button "3". Now point towards the luminaire where the ActiLume sensor is mounted into and press the green button on the selection tool. As a conformation that the selection has been done the lamps will flash once. |
 |
presence detectionWhen using Mode 3 the daylight linking and presence detection are switched on. The presence detection will keep the light on for as long as the sensor detects movement. After the last movement detection ActiLume will keep the lights on for another 15 minutes and will switch off the lights when these 15 minutes have passed. Since Mode 3 is a semi automatic mode, the lights will not be switched on automatically when entering the room. To switch on the lights a separate switch has to be connected to the ActiLume controller. The switch can be located near the entrance of the classroom. This switch is a so called "push to make" switch. The switch will give you a Touch and Dim functionality so it can also be used to dim up and down the lights. |
;) |
| Since the ActiLume sensor is mounted in one of the luminaires near the window and a classroom is rather big this immediately brings the problem of not covering the whole classroom concerning presence detection. To overcome this an extension sensor (LRM 8118/00) can be connected to the system. Since the controller also has to supply the needed operating current for the extension sensor the number of ballasts in combination with extension sensors is limited. The combinations are as follows:
|
 |
Daylight linkingApart from the presence detection there is also a daylight linking mechanism. This will keep the light level at the work area at a constant level. This light level is independent of the amount of light that is coming through the windows. ActiLume will adapt the amount of artificial light so the light level at the work area will stay constant. The default set-point of Philips ActiLume is set at 600 lux with a reflection of 30% and can easily be changed. |
;) |
Automatic offsetEverybody knows that when you have a daylight regulating system that the amount of light near the windows is too high or the light level at the corridor side of the cell office is too low. This issue is solved within the ActiLume controller and this is what makes this system so unique. Thanks to the two outputs (window and corridor side), the settings of the lighting control are pre-programmed according to the place of the luminaire. Therefore the Philips ActiLume system does not require any programming or commissioning. Within Mode 1 (cell office mode) an offset of 30% is pre-programmed between these two outputs so you will always have enough light at the corridor side of the office and still benefit of the daylight linking system. |

presence detectionWhen using Mode 3 the daylight linking and presence detection are switched on. The presence detection will keep the light on for as long as the sensor detects movement. After the last movement detection ActiLume will keep the lights on for another 15 minutes and will switch off the lights when these 15 minutes have passed. Since Mode 3 is a semi automatic mode, the lights will not be switched on automatically when entering the room. To switch on the lights a separate switch has to be connected to the ActiLume controller. The switch can be located near the entrance of the classroom. This switch is a so called "push to make" switch. The switch will give you a Touch and Dim functionality so it can also be used to dim up and down the lights. |

| Since the ActiLume sensor is mounted in one of the luminaires near the window and a classroom is rather big this immediately brings the problem of not covering the whole classroom concerning presence detection. To overcome this an extension sensor (LRM 8118/00) can be connected to the system. Since the controller also has to supply the needed operating current for the extension sensor the number of ballasts in combination with extension sensors is limited. The combinations are as follows:

Daylight linkingApart from the presence detection there is also a daylight linking mechanism. This will keep the light level at the work area at a constant level. This light level is independent of the amount of light that is coming through the windows. ActiLume will adapt the amount of artificial light so the light level at the work area will stay constant. The default set-point of Philips ActiLume is set at 600 lux with a reflection of 30% and can easily be changed. |
 |
Automatic offsetEverybody knows that when you have a daylight regulating system that the amount of light near the windows is too high or the light level at the corridor side of the cell office is too low. This issue is solved within the ActiLume controller and this is what makes this system so unique. Thanks to the two outputs (window and corridor side), the settings of the lighting control are pre-programmed according to the place of the luminaire. Therefore the Philips ActiLume system does not require any programming or commissioning. Within Mode 1 (cell office mode) an offset of 30% is pre-programmed between these two outputs so you will always have enough light at the corridor side of the office and still benefit of the daylight linking system. |

Wing and Sola make up the Icarus installation which we exhibited at the 2010 Milan furniture fair. It was based on the Greek myth of the boy who flew too close to the Sun. If flown well, a wing can soar effortlessly in balance. If we get too ambitious we lose that balance. Sola is the other part of the Icarus installation, the Sun which gets too hot if you fly too high! The cutout shapes look a little like the flares that form and curl on the surface and edge of the Sun.

There have been new developments to the Ulu design, to align it closer in scale to our other lights and to the 'breadfruit' tree ('Ulu' in Tahitian) which was the inspiration for its design. It now has smaller shapes and more of them, creating a tighter pattern. It is also available as a half Ulu, and painted one or two sides. If painted on one side, the coloured side alternates inside/outside because of the way the light is built. Staining on both sides is available on request.

After the recent launch at
Being built in 1907, this gracious Edwardian Baroque building was designed by notable Oamaru architect John Forrester. Recently being completely restored to its original glory, Mark Herring Lighting was approached to provide an architectural lighting solution for the building that would reflect its grandeur and heritage, without polluting the daytime image of the building and working within the constraints of the Historic Building requirements. The integration of classic architecture with modern lighting was achieved through the innovative use of Colour Kinetics dynamic colour LED’s, a solution that won a commendation at the recent Illuminating Engineering Society (IES) Lighting Awards. With the input of Modus designer, Chris Bryne, various plans were considered, but working with coloured light is architecturally demanding, so real trials were required to understand and validate the effects. After several evening trials, creating surmountable local interest and snapshot opportunities, the best solution found was to mount the lighting within the casement windows, with fittings mounted on the window sill, and additional fittings being added to backlight the crowning balustrade. The DMX lighting control system, powered by a Colour Kinetics iPlayer 3 allows a flexible and unlimited colour scheme and variation that can be customised to the client’s requirement. MHL’s sustainable solution lights the entire building for 1kw with virtually no maintenance, creating additional attention to the historic white stone building, which is now fast becoming a lighting icon and tourist attraction in the region.
The green story is having a big impact on the lighting industry, whereby the whole industry is becoming more environmentally conscious. The total costs of ownership is becoming a buzz word in all industries, and none more so than in lighting, where clients and suppliers alike, are becoming more concerned with the lifetime cost of ownership, which includes the power usage and maintenance during the products life expectancy, rather than simply the initial outlay cost. Energy efficiency, carbon footprints and sourcing products that are made from recycled or recyclable materials are key trends driving innovation in the lighting industry. As a company, Mark Herring Lighting continually strives to source more sustainable lighting options and minimise the pressure we place on the environment.
Even though the award winning LED lighting solution for the Oamaru Opera House is a fine example of what can be achieved with high quality LED’s, in both aesthetics and energy efficiency, people should still be cautious in purchasing LED’s. As industry acceptance has been gathering for LED lighting technology, the world has been flooded with these products. Some of these are of exceptional quality, but many develop inferior LED’s to push towards mass markets at a cheap price, and these have the potential to tarnish the market perception of LED technologies. The use of low grade LED’s can reduce, if not neutralise, the environmental benefits of using this technology, as their longevity, reliability, maintenance costs and production methods are all compromised.
Aesthetics is always important in lighting design, as environmental awareness and acceptance comes easier when it looks good. Europe tends to drive the New Zealand market more than the United States when it comes to trends and product designs. Mark Herring Lighting ensure that they are always at the leading edge of lighting design and environmental issues, constantly being in collusion with their European suppliers, attending the Frankfurt Light and Building Tradeshow for the last four years.
If you are in the vicinity, take an evening stroll and peruse the historic Oamaru Opera House, the lighting accentuating its previous glory and look upon what is fast becoming a tourist icon, not only in Oamaru, but for the whole of New Zealand.
