It produces 825 lumens at 77 degrees F with a cool white phosphor that delivers a 4200K color temperature and a Color Rendering Index of 60. The medium bi-pin base provides a secure connection to compatible preheat starters and ballasts. This lamp is a standard replacement for commercial, institutional, and light industrial lighting applications and is typically serviced by electricians or qualified lighting maintenance personnel.\u003c\/p\u003e\u003cp\u003eThis lamp fits preheat-type fluorescent fixtures commonly found in older commercial and institutional installations, including offices, schools, storage areas, and utility spaces. The T8 tube shape and medium bi-pin base are standard configurations in preheat-ballast systems. With a rated lamp life of 7500 hours at a 3-hour start cycle, it is suited for locations where lights remain on for extended periods per switching event. The cool white color output works well in task and ambient lighting environments where neutral to slightly cool illumination is preferred.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e15-watt T8 preheat fluorescent lamp with 825 initial lumens at 77 degrees F\u003c\/li\u003e\n\u003cli\u003e4200K cool white phosphor for neutral, slightly cool color output\u003c\/li\u003e\n\u003cli\u003eColor Rendering Index of 60, appropriate for general commercial and utility lighting\u003c\/li\u003e\n\u003cli\u003eRated 7500 hours lamp life based on 3-hour start cycles\u003c\/li\u003e\n\u003cli\u003eMedium bi-pin base for compatibility with standard preheat lamp holders\u003c\/li\u003e\n\u003cli\u003e18-inch nominal length; tube diameter 1.093 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for preheat fluorescent fixtures using T8 medium bi-pin lamps at 18-inch nominal length.

De-energize the fixture and allow the lamp and any associated components to cool before handling. Preheat fixtures require a compatible starter; inspect and replace the starter if the lamp flickers or fails to strike reliably.
