270W LED High Bay Retrofit Lamp, 4000K, 120–277V From Light Efficient Design

The Light Efficient Design LED-8242M40D retrofit lamp brings 38400 lumens of 4000K light to an HID High Bay fixture. This 270W retrofit replaces up to 1000W HID lighting, offering a way to upgrade a high-ceiling warehouse or manufacturing space while retaining a suitable existing housing.

Working with 120–277V inputs and with an EX39 mogul base, this LED lamp features active cooling to manage operating heat. Wired 0–10V dimming lets you lower output to 20%. A 12V auxiliary output supports compatible sensors. Have a qualified electrician bypass the ballast before installation.
