Performance of Many LED Site Luminaires on the Market Inadequate for Large Area Outdoor, Roadway or Site Lighting Use

Prematurely Introduced Outdoor LED Lighting Not Performing as Marketed; Prove Detrimental to Users, Commerce and Environment

CITY OF INDUSTRY, CA--(Marketwire - October 16, 2008) - Kim Lighting, a leading manufacturer of outdoor architectural lighting, released a much-anticipated white paper on the lighting industry's overall failure to properly bring commercial outdoor LED lighting to market. Titled "Why Today's LED Site and Area Luminaires Are Not Measuring Up," the white paper explores the challenges associated with using LED technology for outdoor lighting to achieving results that are sustainable and do not sacrifice performance.

Findings in the white paper include:

--  As LED developers continue to research and design new manufacturing
    processes, phosphor compounds and color calibration techniques, LEDs will
    become the preferred technology for indoor and outdoor lighting.
--  White light LED technology is still in its earliest stages of
    development and it is counter-productive for the industry to introduce
    products that deliver LED lighting, however sacrifice performance.
--  The general performance of LED site luminaires on the market today are
    not properly designed or adequate for large area outdoor, roadway, or site
    lighting use.
--  Prematurely introduced LED site and area luminaires are not performing
    as marketed when tested under current IES standards.
--  The total efficiency of a luminaire is less relevant when lighting
    outdoor tasks due to the absence of inter-reflections between walls, floor,
    and ceiling.  The true efficiency of an outdoor luminaire should be
    expressed as its ability to deliver lumens in its intended direction, limit
    spill light, and ultimately create a comfortable, glare-free nighttime

The white paper evaluated one existing LED site luminaire from a known manufacturer by several accepted standards of outdoor site lighting, not simply efficiency. The evaluation found the luminaire to fall below the standard needed to properly light an outdoor site in its distribution, efficiency and spacing. Details of the evaluation are found in the white paper.

"LED technology has changed the industry, and promises even greater change in the not-too-distant future," said Bill Foley, vice president and general manager of Kim Lighting. "While its potential for use with large area site lighting or roadway applications is evident, no manufacturer has yet to achieve the efficiency and performance levels necessary to warrant its use in this way. Kim Lighting understands these challenges and will be first to develop innovative LED area light solutions that perform as promised."
