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.
  • No fixture replacement required
  • Lower installation cost and labor time
  • Significant energy savings compared to HID and halogen
  • Reduced heat output and longer lifespan
  • Ideal for budget-conscious upgrades and phased retrofits

Common Retrofit Applications

LED retrofit bulbs are widely used in both indoor and outdoor fixtures where the housing is still in good condition.
  • Wall packs and outdoor area lights
  • Post top and decorative pole fixtures
  • High bays and low bays
  • Recessed cans and downlights
  • Landscape and architectural fixtures
  • Enclosed and semi-enclosed luminaires
