Description
Overview
The Primelite 11074 Round LED UFO High Bay is engineered for high-performance lighting in warehouses, manufacturing facilities, gymnasiums, and service bays. Its molded polymer housing offers a significantly lighter alternative to traditional die-cast high bays while maintaining superior thermal management, so the fixture stays cool and lasts longer under continuous operation. This 11074 configuration ships with a frosted polycarbonate drop lens for smooth, glare-controlled light distribution, paired with a 30,000 lumen output at 5000K for bright, neutral-white illumination ideal for task-intensive environments.
Key Features
The 11074 weighs just 15 lbs, making it considerably lighter than comparable die-cast high bays without sacrificing durability. An IP65 rating protects the fixture against dust and water jets, while the thermally conductive polymer housing manages heat efficiently to extend operational lifespan. The fixture is designed for quick, contractor-friendly installation via a mounting hook, with a central threaded post that secures the LED array and is sealed with a liquid-tight plug. A cord grip boss accommodates ¾” NPT/M20 fittings for flexible electrical hookup.
