New DOE Caliper Snapshot Report on LED Troffers and Troffer Retrofit Kits

Troffers are a staple of the lighting industry, providing economical ambient lighting in offices, schools, and commercial spaces. They come in a variety of form factors, typically 2×4, 2×2, and 1×4, and have traditionally utilized a variety of optical systems, such as lensed or louvered, to meet different needs or to simply provide a different appearance. This CALiPER Snapshot report includes data for both troffer luminaires and troffer retrofit kits. Notably, troffer retrofit kits may or may not reuse the existing luminaire’s optical system (e.g., lens), which will affect the performance of the complete system. A product using the existing luminaire’s optical system will have a lower efficacy than when it is tested by itself. This introduces a confounding factor when making comparisons using aggregate data in the LED Lighting Facts database. https://energy.gov/sites/prod/files/2016/12/f34/snapshot2016_troffers.pdf
