Identification & Application

Topaz LHB-18L-W-40K-U LED Linear High Bay, 120W, 4000K, 18000 Lumens, 120-277V

The Topaz LHB-18L-W-40K-U LED Linear High Bay is designed for commercial and industrial high-ceiling applications requiring efficient, uniform illumination. Typical installations include warehouses, manufacturing facilities, gymnasiums, retail environments, and other open indoor spaces.

This fixture delivers 18,000 lumens of 4000K neutral white light while operating at 120 watts. The optically enhanced wide-beam lens provides broad light distribution with reduced glare, supporting visual comfort in elevated mounting applications.

The housing is constructed from die-cast aluminum with a centrally located driver compartment for durability and thermal management. A white powder-coated finish and damp-location rating allow use in a wide range of 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 occupancy sensor and lighting control compatibility for energy-saving operation.

Suspension mounting hardware is included for installation, while optional surface mount brackets, pendant mount brackets, and wire guards are available separately. The fixture is suitable for typical mounting heights between 15 and 20 feet and replaces traditional HID and fluorescent high bay systems.
