Power management company Eaton announced that its Neo-Ray Index light-emitting diode (LED) luminaires are helping to improve the lighting performance while lowering energy usage in the Gumberg Library at Duquesne University in Pittsburgh. Recently completed on its first floor, this LED lighting upgrade will help the university reduce its annual energy consumption for the floor significantly.
The memorial chapel at Mossley Hill Church in Liverpool is benefiting from a new lighting scheme and control system designed by Cundall Light4. The scheme, which features the award-winning Concord Beacon Muse LED, offers energy-saving and aesthetic benefits which highlight the interior architecture of the historic building.
The Mossley Hill Church redevelopment has architectural elements that combine to make this chapel an exceptional space within one of Liverpool’s finest Victorian Churches. The brief was to design an energy-efficient scheme that could deliver a variety of lighting scenes to suit the wide varieties church services including prayer meetings, group discussions and readings.

Good lighting not only enables people to see, it affects how they feel. Energy efficient lighting can help enrich office life and reduce the energy demands on a building. Lighting is one of the most attractive ways to save energy as older, inefficient lighting technology can account for 40% of the office electricity bill.
Companies can benefit from efficient and effective office lighting. Today’s workplace is a complex and fluid environment, involving a wide range of visual tasks.
Lights run in recreational facilities for extended periods of time, resulting in high electricity bills. Even when patrons aren’t in the facility, lights may be left on for a janitorial crew. By installing energy efficient lights you can reduce energy costs and heat gain. Installing sensors controlled by occupancy and natural light levels can reduce your costs.
Because recreational facilities typically have high energy consumption, upgrading to energy efficient technologies can significantly reduce their energy and operating costs – both immediately and for years to come.
Everyone knows the places well. They are the comforting light that is barely visible along the long, dark and lonely highway. Quick shop, neighborhood grocery or convenience store, whatever the name, we all know what they mean. Whether it’s candy bars, cigarettes, or a tank of gas and a good cup of joe, the good old quickie mart is there to grant your every wish—24 hours a day, 7 days a week, holidays and hurricanes too.
DENVER – Denver International Airport (DIA) is retrofitting more than 5,400 lights located in the airport’s east and west parking garages with energy-efficient LED fixtures.
The majority of the lights are being replaced with 51-watt LEDs. Combined with other lighting systems in the project, DIA expects a net energy savings of about 45 percent, resulting in energy cost savings of about $327,000 per year. Continue reading
A fundamental paradigm shift in lighting technologies toward more efficient lamps and bulbs will significantly reduce global electricity demand for general illumination in the next few years, according to IHS.
The energy usage of the installed base of lighting technologies for general illumination will fall to a projected 2.75 trillion kilowatt-hours (kWh) by 2020, down 24% from 3.61 trillion kWh in 2013. Overall, the installed base for general lighting-which covers homes, businesses and street lamps but not architectural or theatrical lighting-will account for 10.3% of the net electricity generated in 2020, down from 16.4% in 2013.

Consumers in the United States have been witnessing the gradual disappearance of old general-purpose incandescent light bulbs from store shelves since 2012. This is happening because of the adoption of the Energy Independence and Security Act of 2007, which bans the manufacture and sale of certain bulbs. The 100-watt bulb was the first to go, phased out in 2012. It was followed by the 75-watt bulb this year. Now, as 2014 begins, 40- and 60-watt bulbs will begin to disappear as well. Retailers will be able to sell existing inventory, but no new bulbs with these wattages will be made.
The other day I found myself at a loss in the light bulb aisle of my hardware store. I might as well have been shopping for a carburetor. There were too many options with too many symbols and verbiage that I couldn’t decipher (LED, CFL, halogen, lumens, Kelvin, CRI), not to mention all of the various brands (GE, Philips, Cree, EcoSmart — each with its own packaging lingo). Since when do you need an electrical engineering degree to buy a light bulb?
Dubai Municipality, one of the main administrative departments of the Emirate of Dubai government, has signed a memorandum of understanding (MOU) with Philips to convert all of the municipality’s lighting to LED. The agreement embraces all 262 of the municipality’s buildings, including city government offices, schools, public buildings such as courts and sports venues, and transportation buildings. The transformation from conventional lighting to LED is expected to save the Municipality up to 50 percent, roughly 10.5 GWh per year, on its energy consumption. It will also mean a reduction of some 6,200 tons of CO2 emissions per year.
