LED HID retrofit bulbs are engineered to provide a high-performance upgrade for outdated metal halide and high-pressure sodium fixtures. These powerful energy-saving replacements are available in both ballast-bypass and ballast-compatible formats, allowing you to modernize your existing housings without the cost of a full fixture replacement. Delivering up to 50,000 hours of reliable performance, these "corn cob" style lamps significantly lower maintenance costs while providing superior lumen output and color rendering.
Ideal for parking lots, warehouses, and street lighting, our selection of HID to LED retrofits is designed to withstand the rigors of industrial and outdoor environments. We offer a variety of lumen packages and base sizes, including E26 medium and EX39 mogul bases, to ensure a perfect fit for your specific application. Whether you are illuminating a high-bay facility or securing a commercial perimeter, these retrofits improve lighting quality and energy efficiency with ease.
Technical Selection: Modernizing Your HID Fixtures
Retrofitting HID fixtures requires more than just matching a base size. You must consider the physical dimensions of the housing and the electrical configuration of the fixture.
Ballast Bypass (Type B)
This is the preferred method for long-term reliability. By removing the old HID ballast and wiring the socket directly to line voltage, you eliminate the most common point of failure and maximize your energy savings.
Plug-and-Play (Type A)
Designed for rapid deployment, these bulbs work with your existing HID ballast. While installation is as simple as changing a bulb, the overall efficiency is slightly lower, and the bulb will stop working if the old ballast fails.
Key Considerations for a Successful Upgrade
Medium (E26) vs. Mogul (E39/EX39) Bases
Most high-wattage HID fixtures use the larger EX39 Mogul base to handle the heat and weight of the bulb. Standard wall packs or smaller floods may use the E26 Medium base. Always verify your socket size before ordering to ensure compatibility.
Active vs. Passive Cooling
Because LED HID retrofits generate significant internal heat, they require cooling. Our high-wattage lamps feature passive heat sinks or integrated silent fans to pull heat away from the LEDs. This is especially important in enclosed fixtures like shoeboxes or acorns where airflow is limited.
Omni-Directional Lighting
The "Corn Bulb" design provides 360-degree light distribution, ensuring your existing reflectors work exactly as intended. This provides a uniform wash of light across parking lots and warehouse floors, eliminating the dark spots common with aging HID lamps.
