Application Reports focused on specific product types and design scenarios, offering comparative analysis that put LED performance in context relative to the overall lighting industry and benchmark technologies. Product category investigations included industrial luminaires, OLED luminaires, LED color-tunable products, LED MR16 lamps, PAR38 lamps, LED linear lamps and troffers, and retail replacement lamps. These reports educated the industry on potential issues and important areas for improvement.

Industrial Luminaires

Industrial luminaires are prevalent in both the commercial and the industrial sec­tors, providing economical ambient lighting in warehouses, manufacturing facilities, big-box retail stores, and other large, open indoor spaces. Although the incumbent industrial lighting technologies – high-intensity discharge and fluorescent – are low-cost and relatively efficacious, LED industrial luminaires offer a compelling alternative. Learn more about CALiPER investigations of industrial luminaires

OLED Luminaires

OLED luminaires are a solid-state lighting product that is new to the architectural lighting marketplace and OLED panels, drivers, and transformers are still in a steep curve of development. Goals for OLED lighting products include higher efficacy; longer life; better lumen maintenance over time; even better color quality and wider CCT options; higher efficiency drivers; and robustness under high temperature, high humidity, and rough handling from shipping and installation. Improvements in these areas will make OLED luminaires more accepted in the architectural marketplace, and adopted as a trusted lighting solution. Learn more about CALiPER investigations of OLED luminaires.

LED Color-Tunable Products

Color-tunable LED luminaires are an emerging product category that offer potential benefits beyond the inherent energy efficiency of LEDs. There is reason to believe that color-tunable luminaires will gain market share, but it is important to understand the possible tradeoffs, limitations, and issues surrounding these products so that the industry can work together to address challenges needing attention as the technology matures. Learn more about CALiPER investigations of LED color-tunable products.

LED MR16 Lamps

The MR16 is the most common MR (multifaceted reflector)-type lamp and is a key component of the focal lighting systems used in retail, hospitality, residential, and museum applications. MR16s are unique among directional lamps because they're most often operated at low voltage, and their design is constrained by the small form factor. Beyond the usual performance characteristics, the compatibility of electronic components must also be considered. Learn more about CALiPER investigations of LED MR16 lamps.

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 Linear Lamps and Troffer Lighting

More than half of all the light sources in commercial applications are linear fluorescent lamps, used in a wide range of fixtures, including 2' x 4', 2' x 2', and 1' x 4' troffers. A growing number of LED products are 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.
