270W LED High Bay Retrofit Lamp, 5000K, 120–277V From Light Efficient Design

When a high-ceiling space calls for daylight-white light, Light Efficient Design's LED-8242M50D retrofit lamp delivers 38700 lumens at 5000K. It uses 270W to replace up to 1000W HID lamps in 120-277V High Bay fixtures.

An EX39 mogul base makes it a screw-in retrofit once an electrician has bypassed the ballast and checked the fixture. Active cooling helps control heat during operation. Wired 0–10V dimming reduces brightness to 20%, and 12V auxiliary power is available for compatible sensors, giving you options for controlling warehouse or production-area lighting.
