LED Retrofit Bulbs - LED Replacement Lamps for Existing Fixtures

LED retrofit bulbs are designed to upgrade existing light fixtures to energy-efficient LED technology without replacing the fixture itself. Whether you’re retrofitting a wall pack, post top, high bay, recessed can, or decorative fixture, LED retrofit bulbs allow you to reduce energy use, maintenance costs, and downtime while keeping the original housing in place. This category includes LED replacements for HID, halogen, incandescent, and CFL lamps commonly found in commercial, industrial, and residential lighting systems.
