LED PAR38 Lamps

The PAR (parabolic aluminized reflector) lamp is a common type of reflector lamp that's often used in retail display lighting and other demanding applications where color quality and visual appearance are important considerations. Although the directionality of LEDs makes them well-suited for use in PAR lamps, the effectiveness and utility of conventional halogen PAR lamps present a challenge to SSL. Learn more about CALiPER investigations of LED PAR38 lamps.

LED Troffer Lighting

More than half of all the light sources in commercial applications are linear fluorescent lamps, which are used in a wide range of fixtures, including 2' x 4', 2' x 2', and 1' x 4' troffers. But a growing number of LED products are being offered as energy-efficient alternatives – including T8 LED replacement lamps, integral LED luminaires (2' x 4' and 2' x 2'), and kits to upgrade fluorescent troffers to an LED option. Learn more about CALiPER investigations of LED troffers, tubes, and retrofit kits.

Retail Replacement Lamps

LED replacement lamps are now directly available through many retail outlets. Annual CALiPER testing of A19, G25, candelabra, night light, MR16/PAR16, PAR20, and PAR30 replacement lamps – purchased directly from store shelves – offers insights on performance trends from year to year. Learn more about CALiPER investigations of retail replacement lamps.
