High Bay LED Retrofit Lamps
BEST SELLERS
High bay LED retrofit bulbs offer one of the simplest ways to upgrade existing metal halide, HPS, or other HID (High-Intensity Discharge) high bay fixtures to energy saving LED lighting. These powerful LED bulbs are designed with bases (like Mogul E39) that screw directly into the existing fixture's socket, significantly reducing energy consumption and improving light quality.
Key Features & Benefits:
- Easy Installation: Simple screw-in replacement for existing HID bulbs.
- Energy Savings: Dramatically reduces energy use compared to the HID bulbs they replace.
- Improved Light Quality: Offers better color temperature options and higher CRI (Color Rendering Index) than many HID sources.
- Instant On: Eliminates the warm-up time associated with metal halide and HPS bulbs.
- Long Lifespan: Lasts much longer than HID bulbs, reducing replacement frequency.
Common Applications: Upgrading existing HID high bay fixtures in warehouses, factories, gyms, and other facilities where replacing the entire fixture is not desired or feasible.
Considerations: Ballast Bypass Required: Most LED retrofit bulbs require the existing HID ballast to be bypassed (disconnected and removed) during installation – this requires electrical work. Verify fixture compatibility (size, ventilation). Ensure the existing fixture optics work well with the directional nature of LED light.
