Lighting Emitting Diodes (SSL)

Light Emitting Diodes first appeared in the late 1960s. They were only red and green, some blues. Efficiency was fair but the aim was indication not illumination. Fast forward 30 years and LEDS enter the white light arena. Fast forward another 10 years and LEDS are challenging several traditional lighting applications. Work continues, efficiency improves, cost comes down and the challenges to standard lighting practice become real. LEDS are now mandated for Exit Signs and Traffic Signals. Spots and Floods, MR-16s in white light are readily available. Light levels are rising, efficiency and cost/footcandle are getting competitive when one factors in a lifetime of 50,000 hours. Below are listed typical specifications for several variations. This will someday be the standard lighting tool but there are millions of sockets and many demanding applications which are not quite in reach. As the technology evolves, the barriers will disappear.

LED sources include Philips, TCP, Toshiba.

Many States offer incentives or rebates for using LED lamps. Energy Star maintains a list of those lamps which qualigfy for the Energy Star Designation. To access go to www.energystar.gov.

As of January 6, 2012 more than 30 companies listed various products which have met the Energy Star qualifications. Table below just high;ights a few of the products. All can be obtained through The Industrial Ecology Co LLC.
