Acuity Brands Cphb 18lm Mvolt 50k Led High Bay 134W 18000lm

Product Description

The ACUITY BRANDS cphb 18lm mvolt 50k is a hardwired rectangular LED high bay fixture designed for industrial and commercial overhead lighting applications. Rated at 134 watts with an output of 18000 lumens and a 5000K color temperature, it delivers a cool daylight appearance suited to warehouses, manufacturing floors, and large commercial spaces. Efficacy exceeds 135 lumens per watt, placing it firmly in the high-performance tier for energy-efficient overhead lighting. The fixture runs on a wide voltage range of 120 to 277 volts, making it compatible with standard commercial distribution panels without a dedicated driver or transformer. An acrylic glare control lens reduces harsh hotspots while maintaining broad illumination coverage. Rated at 100000 hours average lamp life, it is built for long service intervals in demanding environments.

This fixture is suited for pendant, surface, or suspended mounting configurations in single-phase or multi-phase commercial and industrial electrical systems. Its compact rectangular profile — 14.44 inches long by 11.52 inches wide by 2.3 inches high — allows it to fit in tight ceiling conditions and simplifies installation where larger fixtures would be impractical. It is a practical choice for new construction retrofits or direct replacements in facilities requiring consistent, high-output overhead lighting with minimal maintenance overhead. Licensed electricians and electrical contractors are the typical installers for this class of hardwired luminaire.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize the circuit at the breaker panel and verify zero voltage with a meter before making any wiring connections. Confirm that the mounting structure — whether pendant, surface, or suspended — is rated to support the fixture weight and meets applicable load requirements. Do not bypass the acrylic lens or operate the fixture with the lens removed, as the lens is part of the glare control design.
