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.

Why Use LED Retrofit Bulbs?
Retrofitting with LED bulbs is one of the fastest and most cost-effective ways to modernize lighting. Instead of replacing the entire fixture, you simply remove the old lamp and install a compatible LED replacement.
Common Retrofit Applications
LED retrofit bulbs are widely used in both indoor and outdoor fixtures where the housing is still in good condition.
Types of LED Retrofit Bulbs Available
This category includes LED replacements for many legacy lamp types, allowing you to retrofit almost any fixture.

We leverage our 33,000 sq ft warehouse and decades of hands-on experience to ensure every retrofit bulb we stock meets the highest standards for performance and durability.
