Notes:
(1) Start time is time from initial power-on to full output with 25°C ambient temperature
(2) Avg Life for the LED and Induction Lamp is for lumen depreciation of 30%. Avg Life for conventional lighting is when 50% of a sample population has burned out; and as a side note, remaining units still emitting light will have lumen depreciation beyond 50%. |
