Product Description
90W LED High Bay Retrofit Lamp, 12900 Lumens, 5000K From Light Efficient Design
Convert HID High Bay fixtures to LED with the LED-8136M50D retrofit lamp from Light Efficient Design. 12900 lumens of daylight-white 5000K light on 90W replaces HID lamps up to 250W, making it a practical choice when you want to retain an existing warehouse or workshop fixture.
This is the 120–277V model with an EX39 mogul base. Its fanless design operates quietly, while wired 0–10V dimming allows output to be reduced to 20%. Use it in open fixtures only, with enough clearance for the lamp. A qualified electrician must bypass the existing ballast before installation.
