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?
Until recently locations with linear fluorescent light fixtures had to put a lot of effort into making the switch to LED lighting. Even though there are many options by countless manufacturers, most linear LED lighting requires real work to install into existing fluorescent fixtures. The fragile fluorescent tubes have to be removed, and then the ballasts must each be rewired for the LED tube light fixtures to work. Then the new LED tubes have to be installed. This is time consuming and a disruption to say the least. Workers strewn about on ladders and power outages are sure to strain any environment.
Birmingham Children’s Hospital recently opened its new state-of-the-art kidney wing, and the star of the show was the new Imagination Light Canvas, created with lighting equipment by Philips Electronics. The canvas was part of The King’s Fund’s “Enhancing the Healing Environment” program. This program was developed with the thinking that a better hospital environment would help patients to feel better throughout the healing process and even get better faster.
The 12th-century French-Gothic Cathedral has been relit with over 400 Philips LEDs.
The new lighting scheme was designed to allow different atmospheres to be created depending on whether a religious ceremony, tourist visit or concert is taking place in the Cathedral. Continue reading
Lights are no longer just for lighting.
With the development of LED lamp technology, the lowly light bulb is doing more than turning on and off. A lamp can be the centerpiece of an environment meant to improve health, moods and even food.
LEDs can create light in multiple colors, generate less heat and use a fraction of the energy of older types of bulbs. And LEDs can be controlled remotely from a PC or smartphone app, as programmable as a television. Continue reading
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?
For facility managers who have taken basic steps to reduce lighting system energy costs, the ability to wring savings out of lighting systems doesn’t end there.
Advances in technology continue to provide additional opportunities for savings. In fact, the average commercial facility could stand to do more than just basic upgrades to its outmoded lighting systems. Options run the gamut — including fixture replacement, daylighting, dimming, advanced control and ballast strategies.
“[A facility manager’s] best bet is to explore the different energy management strategies that are available,” says John J. Brelus, General Electric‘s global product general manager — fluorescent systems. Continue reading
Q. I’m replacing the lights in my home before putting it on the market. Is it better to install LED fixtures, if it’s true that incandescent bulbs are being phased out?
A. From a sales perspective, high-efficiency LED lighting is a nice perk, said Ron Lense, an associate real estate broker at Douglas Elliman in Manhattan. But it may not significantly affect your selling price.
“Everybody loves going green,” he said. “They just don’t necessarily want to pay a lot of extra money for it.”
LED lighting is becoming increasingly popular, he said, and if you install it now, “you’ll be ahead of the curve.” Just be cautious about the fixtures you choose, “because this is emerging technology that is quickly changing.” Continue reading
Technology Foundation STW and Philips has officially launched its “Advanced Sustainable Lighting Solutions” partnership to meet the growing demand for sustainable lighting with the approval of eight research projects.
By 2050, the world’s lighting consumption is expected to have increased threefold. Continue reading

Philips Lighting has revealed laboratory work on an LED-based replacement for fluorescent tubes in which a so called TLED (Tube lighting LED) tube delivered 200 lm/W, including the driver, at a 3000K warm-white CCT. The company said it will bring such a solid-state lighting (SSL) product to market in 18 months to two years.
Philips chose to announce the lab project because of the magnitude of the opportunity for energy savings. Jy Bhardwaj, senior vice president or research and development, said 50% of global commercial lighting uses fluorescent tubes. The best such fluorescent lights operate in the 100-lm/W range so efficiency in that application could double in two years.
In the US, fluorescent lights consume 200 terawatts annually according to Philips. The company said retrofit of all such lighting with 200-lm/W tubes would be the equivalent of 50 medium-sized power plants. Continue reading
