NLPIP, the National Lighting Product Information Program, helps lighting professionals, contractors, designers, building managers, homeowners, and other consumers find and effectively use efficient, quality products that meet their lighting needs. With the support of government agencies, public benefit organizations, and electric utilities, NLPIP disseminates objective, accurate, timely, manufacturer-specific information about energy-efficient lighting products.

Established by the Lighting Research Center in 1990, NLPIP team members are LRC researchers—leading experts in efficient lighting, human factors and technology transfer. The NLPIP product testing laboratory is one of only three non-manufacturer, NVLAP-accredited labs in the US.

NLPIP's research and product testing has spanned several products such as compact fluorescent lamps (CFLs), T5 fluorescent systems, metal halide lamps, dimming ballasts, and occupancy sensors, as well as timely subjects such as light pollution, parking lot illumination, and alternative light sources for exit signs.

Lighting systems are becoming more complicated and harder to specify, install, and commission properly. To help facility managers, lighting specifiers, and building owners, NLPIP is now publishing Lighting Diagnostics reports that document actual cases in which NLPIP researchers have helped to diagnose and solve lighting problems in commercial buildings.
