【 摘 要 】

This CALiPER report examines lumen depreciation and color shift of 17 different A lamps in steady-state conditions (15 LED, 1 CFL, 1 halogen). The goal of this investigation was to examine the long-term performance of complete LED lamps relative to benchmark halogen and CFL lamps???in this case, A lamps emitting approximately 800 lumens operated continuously at a relatively high ambient temperature of 45?��C.
