Linear LED Highbay


Howard Lighting HLED series Linear LED Highbay, 120-277V driver, 0-10V dimmable, 4000K or 5000K. Available in 8,000-24,000 lumen versions.

SKU: HL-HLED Category:


Howard Lighting has upgraded their highbay series to include this linear LED highbay with lumen output ranging from 8,400 to 24,600 lumens.  This is a very versatile fixture that can be suitable for everything from mid ceiling height gyms to large high school gyms.  The linear layout helps reduce visual glare by not concentrating all of the light output into a small point. Since the fixture is larger than traditional highbay fixtures, the light output is spread out over a larger surface area.  The fixture features a full body construction in a white finish with a wiring access plate on the back for quick and easy installation.  There are also holes on either end for V-clip or aircraft cable mounting kits as well as a center pattern for a pendant mount option. The LED light engine is available in 4000K or 5000K color temperature with a CRI of 85 and has a 79% lumen maintenance at 60,000 hours.  The LED driver comes standard with 0-10V dimming and operates between 120-277V.  The HLED series linear LED highbay is UL and cUL listed for damp locations, RoHS compliant and IESNA LM-79 and LM-80 compliant.

Typical Lighting Plan

The layouts below demonstrate the expected average light levels in a 100′ x 100′ space when the linear LED highbay fixtures are mounted at 25′ above the finished floor and are spaced at either 20′ x 20′ or 25′ x 25′. This can be used to judge what the light levels will be in your facility with each of the linear LED highbay models listed.  We would be happy to provide a customized lighting plan for your space.
