For many buildings, switching to more efficient lighting is one of the “low hanging fruit” for improving energy efficiency. Facility managers are increasingly turning to LED lighting technology to meet their energy efficiency goals.
LED bulbs top the lighting charts in energy efficiency and longevity, and frequently represent a payback of three years or less. However, LEDs may not be the best choice for every application. When considering whether to implement LEDs in your facility, you’ll need to take many factors into account. Continue reading
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.
Wherever you go these days, you see businesses switching their lighting systems from old-fashioned incandescent or harsh fluorescent to bright and shiny new LEDs. The local supermarket, the office where you work, the train station, restaurant or department store—all of these businesses are seeing the benefits of this rapidly developing technology. The light produced by LED bulbs is brighter and warmer and more focused than ever before, and business owners love the savings to their energy bills. But what about consumers?
GE Lighting has announced that the city of Oakland, California is in the process of retrofitting 30,000 street lights with GE Evolve LED Roadway Scalable Cobrahead fixtures. The city is converting high-pressure sodium (HPS) lights that range from 70–400W along the breadth of the city’s roadways with the GE product family that offers models that can deliver a variety of lumen packages, as the scalable name implies.
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.
LED-based lighting will enable higher illuminance levels on iconic artwork in famed Rome cathedral while preserving the historically-significant work and utilizing 60% less energy.
Osram’s lighting business has announced that it will be retrofitting the lighting in the Rome, Italy Sistine Chapel, using LED-based fixtures to highlight the Michelangelo frescoes. The project, involving custom-designed fixtures optimized for beam control and with a color spectrum that will highlight the pigmentation in the frescoes, will be completed next year, although a pilot project entitled LED4Art has already proven the concept.

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?
CLEVELAND, Ohio — Residents and motorists in several Cleveland neighborhoods will see their streets in a different light next month — when the warm glow of traditional street lights is replaced by the white illumination of energy-efficient LED’s.
For two years beginning May 1, city-owned Cleveland Public Power will test four varieties of LED street lights on both sides of the city and downtown to gauge efficiency, coverage and how well they hold up to harsh Cleveland weather.
Mayor Frank Jackson first unveiled the plan in 2011, a year after the administration launched an unsuccessful effort to find a company willing to sell the city LED lights in exchange for creating jobs. Continue reading
100 watt incandescent light bulbs are no longer being manufactured. From now until 2014, standard A-line 100 to 40 watt incandescent light bulbs must use 30% less energy but produce the same amount of light that incandescent bulbs use today. Continue reading
