Product Overview
The Lumerica DU-A-NHB-240 is a 240-watt LED high bay fixture from Lumerica's DU-A-NHB series, built for mid- to high-bay commercial and industrial applications. It ships ready to hang, with a cast aluminum housing rated IP65 for wet and harsh locations.
It puts out 33,600 lumens at 140 lumens per watt, with a 5000K daylight color temperature, 80 CRI, and a 90-degree beam angle. A universal 110-277 VAC driver handles 120V, 208V, 240V, or 277V supply without a separate transformer, and the fixture carries a 50,000-hour rated life.
The DU-A-NHB-240 also supports optional plug-and-play motion and daylight sensors and a Zigbee wireless mesh gateway for group control.
Recommended mounting height is 18 to 26 feet, which puts it in the sweet spot for warehouse aisles, manufacturing floors, and other high-ceiling spaces that need wide, even light without a warm-up delay. Installation should be handled by a qualified electrician in accordance with the installation manual and local electrical code. Confirm the supply voltage matches the fixture's rated input, connect the equipment-grounding conductor, and keep power off during installation and any servicing; the driver's 0-10V dimming leads should be capped off if a dimming control isn't in use. The DU-A-NHB-240 carries Lumerica's 5-year limited warranty. See the installation manual and spec sheet for full wiring and mounting details, and call Indiana Radiant if you need help sizing a fixture to your space.
