This document describes a new series of COB high bay LED lighting fixtures designed to replace 150W to 400W metal halide, HPS, or mercury vapor fixtures. The COB high bay fixtures provide 100% of light in a downward direction, resolving issues with metal halide lighting distributing light unevenly. They are recommended for installations 12 to 25 feet high and provide consistent, uniform light quality over a wide area. Key features include a 7-year LED warranty, IP67 waterproof rating, and lumen outputs up to 30,000 lumens.

has designed a new series of COB High Bay LED Lighting Fix-
tures for replacing 150W to 400W Metal Halide, HPS or Mercury Vapor fixtures. These
COB High Bay fixtures are easily installed in place of umbrella fixtures throughout ware-
houses, gymnasiums, grocery stores and airports.
In many industrial locations across the country, companies have been left to accept
non-uniform lighting distribution inside their warehouse space. The reason for this dark-
ness is Metal Halide lighting produces a 360 degree output, meaning a majority of light
generated is lost sideways into the air and does not produce significant downward illumi-
nation. This creates wasted energy, low light visibility and dangerous working condi-
tions. The higher the light fixture is placed, the worse Metal Halide bulbs perform.
Our COB High Bay family was designed to resolve this directional lighting problem
by using high power Chip On Board (COB) LED technology combined with our copper
inlay heat spreading and various degree lens, we can provide 100% of the light generated
in a downward direction and provide excellence in uniformity of light.
COB High Bay is recommended for applications 12 feet to 25 feet in height and provides
consistent uniformity combined with light quality across a wide area.
