Two switches inside the driver housing set this UFO high bay to 180W, 210W or 240W, and to 3500K, 4000K or 5000K. One SKU covers nine configurations.
That's 27,000 to 35,000 lumens, CRI above 80, on a 90 degree beam. Input runs AC120-347V, so it lands on 347V industrial service without a step-down transformer.
IP65, IK08, wet-rated, cULus-listed. 6kV surge protection and a five-year warranty.
Can you run the motion sensor and 0-10V dimming together?
No. The manual rules it out in one line: the fixture can't be connected to a dimming device when it's fitted with a motion sensor. Pick one control strategy per fixture before you order.
Pick the sensor for standalone occupancy control. It twist-locks into the receptacle with no wiring, and a remote sets hold time, standby dim level and standby duration. Pick 0-10V when dimming comes from a panel or daylight controller. The Sosen driver dims 10% to 100% and is tested with Lutron NTSTV-DV, Leviton DS710-10Z and Legrand RH4FBL3PW.
One limit to catch early: the sensor is rated -20°C to +60°C, but the fixture runs to -40°C. In an unheated Canadian warehouse the sensor quits long before the luminaire does.
What ceiling height does the 240W setting suit?
Roughly 25 to 40 feet. The measured photometric file puts 19,254 candela straight down at 240W/3500K, so one fixture delivers about 31 foot-candles directly beneath it at 25 ft, 21 fc at 30 ft and 12 fc at 40 ft. Spacing sets the average, not the fixture. Past 40 ft you lose the sensor option, since that's its detection ceiling.
What does each wattage step actually draw?
Less than the nameplate. The photometric files log 165 to 172W on the 180W step, 193 to 203W on 210W and 223 to 241W on 240W, at a measured power factor of 0.997. At 347V that's about 0.70A per fixture at full output, so a 20A circuit loaded to 80% carries roughly 22. On 120V it's 2.01A each.
How does it mount?
Three ways, not one. The spec sheet lists hook mount only. The manual adds a ceiling bracket and a 1/2" NPT stem, both tilting 50 degrees left or right so you can aim down an aisle. A wire guard, an aluminium or PC reflector and a safety cable are sold separately.
For wiring colours, the sensor setup sequence and the dimming schematic, open the Manual (PDF), and pull the IES set if your designer needs measured candela at every wattage and colour temperature.
