Future Looks Bright for Consumer and Industrial Applications of LEDs

For many reasons, use of LEDs in both consumer and industrial applications looks bright. So believes Richard Evans, an engineer who has talked to environmental groups about consumer use of LEDs and has been specifying LEDs for a leading manufacturer of industrial automation equipment for over 10 years.

Consumer products to use more LEDs in the future
In the consumer sector, he is very optimistic about the growth of LED use, especially when it comes to LEDs replacing incandescent and fluorescent lighting and the use of LEDs in television sets. He predicts “the trend toward LED back lighting in TV sets will continue for several more years.” Continue reading

Shine On, You Crazy Lightbulbs

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?

Part One: Advances In Lighting Technology Give Facility Managers New Options For Savings

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

Lighting Like an Incandescent, Except It’s an LED

By Gregory Schmidt

In the debate over the merits of incandescent light bulbs versus compact fluorescent lamps, LED bulbs have become a viable alternativeSwitch Lighting is hoping to ride the wave of rising consumer interest with its own series of LED bulbs.

Switch assembled a team of engineers and physicists in its Silicon Valley headquarters in 2007, and produced a bulb last year with distinct design that has won several innovation awards.

The bulb incorporates technology that Switch calls a LQD cooling system, a patented design that bathes the LED with a coolant made of liquid silicone. The liquid diffuses the light over the surface of the bulb, producing light that is omnidirectional and illuminating a room similar to the way an incandescent does. The shape is similar, too, for those who prefer traditional A-series light bulbs. Continue reading

Is This The End of T12 Lamps and Ballasts?

What’s Happening?

  • Manufacturers are phasing out production of T12 lamps and ballasts.
  • Less availability of T12 lamps and ballasts.
  • Increased costs, up to triple the normal price, because of supply and demand of T12 lamps and ballasts.
  • To meet energy efficient federal regulations, manufacturers will focus on T8 and T5 lamp and ballast production.
  • There’s a limited opportunity to access incentive funds from utility companies for T12 lighting upgrades. Continue reading
