LED Retrofit Bulbs
(Showing 24 of 449)Explore our selection of LED retrofit bulbs at Light Bulb Surplus. We offer a wide range of LED replacement bulbs designed to upgrade existing fixtures with improved efficiency and long-lasting performance.
LED retrofit bulbs are designed to upgrade existing light fixtures to energy-efficient LED technology without replacing the fixture. These replacement lamps allow you to retrofit wall packs, post tops, high bays, recessed cans, and decorative fixtures by simply swapping the old lamp for an LED equivalent. Ideal for commercial, residential, and maintenance projects, LED retrofit bulbs reduce energy costs, extend service life, and minimize installation time while keeping existing housings in place.
LED Replacement Bulbs for Retrofitting Existing Light 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.
Key Advantages
- 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.
Typical Use Cases
- 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
Types of LED Retrofit Bulbs Available

Important Retrofit Considerations
Before retrofitting to LED, it’s important to confirm compatibility with the existing fixture and electrical setup.
What to Check Before Installing
- Base type (E26, E39, GU24, G24, etc.)
- Voltage requirements
- Ballast compatibility or ballast bypass requirements
- Enclosed fixture rating
- Physical size and clearance inside the fixture
Our product listings clearly specify these details to help ensure a smooth retrofit.
Ideal for Commercial & Maintenance Projects
LED retrofit bulbs are commonly used by:
- Facility managers
- Property management companies
- Electrical contractors
- Municipal and HOA maintenance teams
- Retail and warehouse operators
They provide a practical path to LED upgrades while minimizing disruption and upfront cost.
