Osram FO28/835/XV/SS/ECO T8 Fluorescent Lamp 28W 3500K

Product Description

The OSRAM FO28/835/XV/SS/ECO is a 28-watt T8 fluorescent lamp built to the Octron XV 800 extended-performance specification. It uses a rare-earth phosphor coating to deliver 2600 initial lumens and 2445 mean lumens at 25 degrees C, with a color temperature of 3500K and a Color Rendering Index of 83. The lamp supports both instant-start and programmed rapid-start ballast configurations. Rated life reaches up to 42000 hours on a programmed rapid-start ballast at a 12-hour burn cycle. It is manufactured to ANSI C78.81 standards and carries RoHS and TCLP compliance. Licensed electricians and lighting contractors install this lamp in commercial and light-industrial environments.

This lamp is suited for recessed troffer fixtures, cove lighting, direct/indirect luminaires, and valance applications in commercial, institutional, and light-industrial settings. Its 3500K neutral-white color temperature and 83 CRI make it appropriate for offices, retail spaces, schools, and healthcare facilities where accurate color rendering and consistent light output are required. The lamp is sold individually and is available in cases of 30. When paired with OSRAM QUICKTRONIC electronic ballasts, it qualifies for the QUICK 60-plus system warranty.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize the fixture completely before relamping or servicing the ballast. Verify that the ballast type — instant-start or programmed rapid-start — matches the intended burn-cycle application, as lamp life ratings vary by ballast configuration. TCLP-compliant lamps require proper lamp disposal per applicable local and federal regulations; do not dispose of with standard solid waste.
