Osram FP54/865/HO/ECO T5 Ho Fluorescent Lamp 54W 6500K

Product Description

The OSRAM FP54/865/HO/ECO is a 54-watt T5 High Output fluorescent lamp built on the Pentron platform with rare earth phosphor technology. It delivers 4100 lumens at 77 degrees F and 4750 lumens at 95 degrees F, with a color temperature of 6500K and a color rendering index of 85. The miniature 2-pin base fits standard T5 HO lamp holders. Rated lamp life reaches 40,000 hours at 3-hour start cycles and 45,000 hours at 12-hour start cycles, making it a long-service option for commercial and industrial fixture applications. The lamp is constructed with lead-free glass and measures 0.67 inches in diameter by 45.8 inches in length with a 48-inch nominal length.

This lamp is designed for use in canopy fixtures, high bay luminaires, indirect lighting systems, security lighting, and signage applications. Its high output rating and daylight color temperature make it well suited for commercial interiors, parking structures, and large open spaces where high maintained illuminance is required. The T5 form factor supports compact luminaire designs while delivering greater light output than standard T5 lamps. It is typically installed by licensed electricians or qualified lighting maintenance technicians in commercial and industrial settings.

Installation Notes

Installation should be performed by a licensed electrician or qualified lighting technician. De-energize the fixture at the circuit breaker before removing the existing lamp or accessing lamp holders. Verify that the ballast is rated for T5 HO lamps at 54 watts before installing.
