Lumen and Chromaticity Maintenance of LED PAR38 Lamps Operated in Steady-State Conditions
- Pacific Northwest National Lab. (PNNL), Richland, WA (United States)
The lumen depreciation and color shift of 38 different lamps (32 LED, 2 CFL, 1 ceramic metal halide [CMH], 3 halogen) were monitored in a specially developed automated long-term test apparatus (ALTA2) for nearly 14,000 hours. Five samples of each lamp model were tested, with measurements recorded on a weekly basis. The lamps were operated continuously at a target ambient temperature between 44°C and 45°C.
