Product Description

For a higher-voltage warehouse or manufacturing installation, Light Efficient Design's LED-8242M50D-HV delivers 38700 lumens of daylight-white 5000K light on only 270W. This 277–480V lamp is designed to replace up to 1000W HID lighting while keeping a High Bay fixture in service.
