Identification & Application

Topaz LHB-48L-W-50K-U LED Linear High Bay, 320W, 5000K, 48000 Lumens, 120-277V

The Topaz LHB-48L-W-50K-U LED Linear High Bay is designed for commercial and industrial facilities requiring high-output illumination in large open environments. Typical applications include warehouses, manufacturing plants, distribution centers, gymnasiums, and large retail spaces with elevated mounting heights.

Operating at 320 watts, this fixture delivers 48,000 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-bay 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 performance in demanding commercial and industrial environments.

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 40 and 50 feet and serves as a replacement for traditional fluorescent and HID high bay systems.
