This document is intended to provide clear recommendations and requirements on procedures for seasoning of lamps to attain a state of sufficient stability for reproducible measurement of initial photometric, colorimetric, and/or electrical characteristics. Its methodology applies to normal and accelerated seasoning of incandescent filament lamps, cathode fluorescent lamps, and high intensity discharge (HID) lamps. Manufacturers’ recommendations for seasoning should be followed for lamp types other than those listed above. Lamps intended for use as reference standards require special seasoning.
