Osram F13T5/CW 13W T5 Preheat Fluorescent Lamp Cool White

Product Description

The OSRAM F13T5/CW is a 13-watt preheat fluorescent lamp in a T5 tubular shape, designed for fixture types that use a preheat starting circuit with a miniature bi-pin base. It produces 830 lumens of initial output at 25 degrees C with a color temperature of 4000 K and a color rendering index (CRI) of 60, delivering a cool white appearance suited to task and general-purpose lighting applications. The lamp measures 0.63 inches in diameter and 20.909 inches in length, with a nominal length of 21 inches. Constructed from glass and built lead-free, it carries a rated lamp life of 7500 hours. Installation is performed by licensed electricians or qualified maintenance technicians.

This lamp is used in residential and light commercial fluorescent fixtures designed for preheat-circuit T5 lamps, including undercabinet lighting, display case lighting, and older fluorescent strip fixtures that require the miniature bi-pin base format. The cool white phosphor output makes it well suited to workbench, utility, and retail display environments where neutral to slightly cool illumination is preferred. It is sold individually and is also available in a 25-unit case pack.
