Light Efficient Design LED-8091M40D-HV LED Shoe Box / Wall Pack Retrofit Lamp - EX39 - 320W - 4000K - 43,380 Lumens - 277V-480V

Light Efficient Design’s LED-8091M40D-HV is a 320-watt LED retrofit designed to replace high-output HID shoebox and wall-pack fixtures when used with an enclosed, glass-lens housing. The lamp operates across a wide input range of 277–480V and delivers approximately 43,380 lumens at a 4000K color temperature, making it suitable for area lighting applications that previously relied on 1000W HID sources. It features an integrated active cooling system and a thermal sensor to help sustain lumen performance and extend fixture life. The unit includes built-in support feet to guard against socket sag and provides 10kA surge protection for safety in demanding environments. When installed on an appropriate enclosed fixture, the lamp can be dimmed to 50% using the switch on the lamp, offering some flexibility for different lighting needs.

This model is specifically labeled as an EX39/Mogul base retrofit and is intended for use in fixtures that are enclosed and wired for high-lumen LED operation. The design supports long life, with a rated 50,000 hours of operation, and is listed to meet industry-standard performance expectations for retrofits that replace 1000W HID lamps. The compact dimensions (approximately 12.6 in length, 8.9 in width, 3.6 in height) help determine compatibility with existing housings, while the 4000K color temperature provides a neutral white illumination suitable for outdoor and large-area spaces. The fixture’s construction and cooling features are important because they influence sustained lumen output and reliability in hot or challenging electrical environments.
