Product Testing

The LRC evaluates and tests lighting technologies, products, and systems to provide accurate, objective, third-party performance information. These evaluations - with support from government agencies, public benefit organizations and electric utilities - help the LRC to promote effective and energy-efficient lighting solutions, influence the market, and build industry consensus.

Concern over potential legal repercussions, expense, and technical burdens of product testing often prevent organizations from testing products and reporting brand-name information. As a result, such groups have funded LRC programs such as NLPIP (National Lighting Product Information Program) in an effort to disseminate objective, accurate, timely, manufacturer-specific information about energy-efficient lighting products.


Lighting Answers: LED Residential Under-cabinet Luminaires - This publication provides information about LED under-cabinet luminaires that were available in consumer-oriented retail stores in the spring of 2009. Four available linear under-cabinet luminaires intended for kitchen applications were tested to determine the amount of light each provides on countertop and backsplash areas, the uniformity and color of the light, and the efficacy of the luminaires. Traditional fluorescent and incandescent xenon models were tested for comparison. This report discusses the results of the performance testing, energy and financial savings, and other considerations such as warranties.

Lighting Answers: Availaibility of LED Lighting Products for Consumers - This publication provides information about the general illumination LED products that were available in consumer-oriented retail stores in the Albany, N.Y., area in the spring and fall of 2009. The types of products available for sale were power failure lights, task lights, replacement lamps (commonly referred to as light bulbs), night-lights, and under-cabinet luminaires.

Specifier Reports: Low-wattage Metal Halide Lighting Systems - A detailed report on the operation of metal halide lamps of 150 watts or less on magnetic and non-dimming electronic ballasts, including product testing.

Specifier Reports: Screwbase Compact Fluorescent Lamp Products - This issue of Specifier Reports contains performance data for compact fluorescent lamps (CFLs) rated at or above 13 watts. The report includes NLPIP test data and manufacturers' data on both self-ballasted CFLs and modular CFL products that are sold with ballast and lamp packaged as a single unit.
