Osram FBO31/830 U-bend Fluorescent Lamp 31W T8 3000K

Product Description

The OSRAM FBO31/830 is a 31-watt T8 U-bend fluorescent lamp designed for instant-start and rapid-start electronic ballast systems. It produces 2,725 initial lumens at a 3000K color temperature, delivering warm white light with a color rendering index (CRI) of 82. The frosted finish diffuses light evenly across a full 360-degree beam spread. Rated for 20,000 hours of average life, this lamp is suited for commercial drop-ceiling troffers and residential utility fixtures where U-bend geometry is required. Licensed electricians and lighting contractors are the primary installers. The lamp is RoHS compliant and ships individually, with a standard carton quantity of 15 units.

This lamp fits standard U-bend fluorescent fixtures found in commercial office spaces, retail environments, schools, and residential utility areas. It operates on electronic ballasts configured for instant-start or rapid-start operation meeting ANSI specifications. Average rated life of 20,000 hours is based on 3-hour burn cycles per start on instant-start ballasts; operating on longer cycles extends rated life. Initial lumen output is measured after 100 hours of operation. The G13 medium bi-pin base is the standard interface for T8 U-bend fixtures, making this lamp a direct fit in the majority of U-bend troffer housings.
