The LED UFO Light carries three switches on one fixture: wattage, colour temperature and beam angle. Set 80W, 100W or 150W. Pick 3500K, 4000K or 5000K. Then choose a 60°, 80° or 100° beam to suit the ceiling.
Output runs 11,300 to 21,100 lumens at the 100° setting, with CRI above 80. Input is AC120-347V, so one part number covers most Canadian services.
Die-cast aluminum, IP65, cULus wet location, five-year warranty.
What is a UFO high bay light?
It's a round, disc shaped fixture built for ceilings above roughly 15 feet. The shape comes from the finned aluminum heat sink that cools the LEDs without a fan. This one replaces a 450W metal halide, so connected load drops by about two thirds, and you get instant restrike with none of the lumen slump an ageing HID lamp brings.
How many UFO high bay lights do I need?
Beam angle decides that as much as wattage does. A 100° beam spreads wide, so fewer fixtures cover an open floor at a low mounting height. A 60° beam drives the same lumens into a tighter cone, which is what you want over 25 foot racking or between narrow aisles, where wide light just washes the shelf sides. Since this fixture switches between all three on site, you can test a layout before you commit to a count.
Which beam angle should you choose?
Start at 80° for general warehouse and shop floors. Drop to 60° when mounting height climbs past about 25 feet, or when you're lighting between racks. Use 100° for lower open bays and garages where even fill matters more than punch. The beam selector and the CCT selector are switches on the fixture, marked 60° 80° 100° and 35K 40K 50K, so your electrician sets both at install and you stock one part number.
What it pairs with, and what it won't
One limit matters more than the rest. The manual states the fixture can't be connected to a dimming device when it's fitted with a motion sensor, so pick one or the other. Dimming is 0-10V across a 10 to 100 percent range, tested with Lutron NTSTV-DV, Leviton DS710-10Z or IP710, and Legrand RH4FBL3PW. The sensor twist locks into the base, no wiring, ordered separately. Mounting is hook, ceiling bracket or 1/2 inch NPT, and the bracket options tilt 50° either side. NSF coverage is splash zone and non food zone, so keep it clear of exposed product lines.
For wiring colours, the three dimming methods and the ceiling and NPT mounting steps, open the Manual (PDF), and ask us for the photometric files if your designer is running a layout.
