How Many OTAT 84w LED High Bay Fixtures Do I Need?

Different projects require different light levels. However, Access Fixtures has already done the heavy lifting to make sure you select the perfect fixture for you. We’ve run many photometric reports for these fixtures and, using our in-house calculator, can tell you exactly how many fixtures you need to illuminate your area to the appropriate light levels. Of course, if you have a particularly unique space, we can also run a custom photometric analysis for you. Call our team at 800-468-9925 to discuss.

Beam Angle & Distribution

Lifetime: 50,000 Hours

OTAT LED High Bays are L70 rated for 50,000 hours. This rating means that after 50,000 hours of use, the units will emit 70% of the light they emitted when they were first installed. The units will continue operating beyond that time, but after 50,000 hours, you may be ready to consider replacements.


The drivers in these units are built with the standard option for 0-10v dimming. This makes your units compatible with just about any 0-10v dimming switch. Of course, if you don’t need dimming, simply have your electrician use the standard wiring, also included.

Housing & Mounting

OTAT LED high bays feature die-cast housings and acrylic, polycarbonate lenses. These commercial-grade high bay fixtures all come with 41″ chains and V-hooks for easy mounting. These units are suited for dry/damp locations and are intended for indoor applications.

Ratings, Listings, & Warranty

Buy with confidence. These fixtures are backed with UL and FCC listings and a 5-year warranty. Our customer service team based out of Worcester, MA, is on-call whenever you or your electrician need additional information.

Line Voltage Compatibility

OTAT high bay fixtures will auto-sense line voltages between 120v and 277v. Need a high-voltage (347-480v) option? Call Access Fixtures today for pricing and availability.
