Identification & Application

Topaz LHB-63L-W-50K-U LED Linear High Bay, 420W, 5000K, 63000 Lumens, 120-277V

The Topaz LHB-63L-W-50K-U LED Linear High Bay is engineered for commercial and industrial facilities requiring maximum light output in very large spaces with high mounting elevations. Typical applications include warehouses, manufacturing facilities, distribution centers, gymnasiums, aircraft hangars, and expansive industrial environments.

Operating at 420 watts, this fixture delivers 63,000 lumens of 5000K daylight-white illumination. The optically enhanced wide-beam lens and diffused optical system provide broad, uniform light distribution while minimizing glare and improving visual comfort in high-ceiling applications.

The luminaire features a die-cast aluminum housing with a center-mounted driver compartment engineered for durability and thermal management. The white powder-coated finish and damp-location construction support dependable long-term performance in demanding commercial and industrial settings.

A universal voltage driver accepts 120-277V input power and includes standard 0-10V dimming capability. The integrated low-voltage sensor receptacle supports compatibility with occupancy sensors and lighting controls for advanced energy management.

Suspension mounting hardware including V-hook and chain is included. Optional surface mount brackets, pendant mount brackets, and wire guards are available separately. The fixture is intended for mounting heights between 50 and 60 feet and serves as a replacement for traditional 1000W HID high bay systems.
