Osram F72T12/CW T12 Fluorescent Lamp 55W Cool White

Product Description

The OSRAM F72T12/CW is a 55-watt T12 slimline instant-start fluorescent lamp designed for high-output linear lighting applications in commercial and industrial fixtures. Running at a color temperature of 4200 Kelvin and delivering a cool white phosphor output, this lamp produces 4500 lumens of initial intensity with a color rendering index (CRI) of 60. At 70 inches nominal length and 1.59 inches in diameter, it fits standard slimline single-pin tombstone sockets. Rated at 12,000 hours of lamp life, it meets ANSI C78.81 standards. Electrical and lighting contractors install these in warehouses, gymnasiums, and large open-ceiling commercial spaces.

This lamp is suited for slimline instant-start fluorescent fixtures commonly found in commercial and industrial settings, including retail warehouses, manufacturing facilities, gymnasiums, and large open-ceiling interiors. The instant-start circuit ignites the lamp without a preheat cycle, making it appropriate for fixtures wired with single-pin slimline ballasts. It is not intended for use with preheat or rapid-start ballasts. Electrical contractors and lighting maintenance crews typically specify this lamp for high-bay and strip-light fixture retrofits and replacements requiring a 70-inch T12 slimline format.
