UFO High Bay Light oH Series

E-commerce fulfillment centers process 2,000–5,000 picks per hour per worker, making precise aisle illumination critical for speed and accuracy. At 150 lm/W, the oH Series UFO High Bay delivers 9,000–36,000 lumens across 60–240W options — replacing 250–1,000W metal halide fixtures with 55–65% energy savings. IES RP-7-21 recommends 30–50 fc at floor level with ≤3:1 uniformity ratio for active picking zones, and the integrated 0-10V dimming enables occupancy-controlled strategies that save an additional 30–50% in low-traffic aisles. DLC 5.1 certified for utility rebate eligibility across all major U.S. programs, with typical payback under 18 months even without incentives. Request a free LightSpec AI photometric layout to optimize fixture count and spacing for your specific rack configuration and ceiling height.

Manufacturing quality inspection at production-line speed demands 50–100 fc of flicker-free, high-CRI illumination with minimal shadowing across workstations. The oH Series delivers CRI >80 across all wattages with <3% flicker at frequencies invisible to both workers and high-speed cameras — critical for machine vision systems running at 120+ fps. At 150 lm/W, a 240W fixture produces 36,000 lumens while consuming 60% less power than the 400W HID it replaces, and the 100–480V universal input eliminates voltage compatibility issues in facilities with mixed electrical infrastructure. OSHA 1910.303 compliance is simplified with IP65-rated housings that resist metal dust, coolant mist, and wash-down protocols. Use the free LightSpec AI tool to model vertical illuminance at inspection stations and ensure IES RP-7 task-plane requirements are met before ordering.

Cold storage and food processing facilities operate at temperatures from -20°F to 40°F with constant humidity, wash-down cycles, and strict sanitation requirements — conditions that destroy conventional fixtures within 2–3 years. The oH Series IP65-rated, fully gasketed housing with corrosion-resistant die-cast aluminum survives these environments for 100,000+ hours without condensation ingress or seal degradation. At 150 lm/W, a 100W unit delivers 15,000 lumens — sufficient for 15–25 fc in cold storage aisles per IES RP-7 guidelines — while consuming 75% less energy than the 400W HPS fixtures still common in aging refrigerated warehouses. NSF/ANSI 2 compatible housings with smooth, non-porous surfaces support USDA and FDA sanitation protocols. DLC certification qualifies for utility rebates that typically cover 30–50% of fixture cost.

Big-box retailers like Costco, Home Depot, and Sam's Club operate with 20–35 ft exposed ceilings where lighting directly impacts merchandise appearance, customer dwell time, and shrinkage rates. IES RP-2 recommends 50–75 fc in general retail with ≤3:1 uniformity and CRI ≥80 for accurate color rendering of products. The oH Series UGR<19 optics eliminate the harsh glare that causes customer discomfort and headaches during extended shopping visits — a capability most competing UFO high bays cannot match. At 150 lm/W, the 200W model delivers 30,000 lumens while consuming $26/year in electricity (at $0.15/kWh, 12hr/day operation) compared to $65/year for the 400W metal halide it replaces. DLC certification enables utility rebates of $50–$150 per fixture across most U.S. utility territories.

Gymnasiums, fitness centers, and community recreation facilities require 30–75 fc of glare-controlled illumination where occupants are frequently looking upward — making UGR the single most important specification after light level. The oH Series achieves UGR <19, meeting IES RP-6 Class III recreational lighting standards without supplemental louvers or aftermarket glare shields that reduce output and increase cost. At 150 lm/W, the 200W model delivers 30,000 lumens — enough to light a standard high school gymnasium (84×50 ft) to 50 fc with just 12 fixtures, compared to 20+ conventional 250W UFO high bays. The 100,000-hour rated life eliminates maintenance disruptions in facilities where ceiling access requires scissor lifts and event scheduling coordination. 0-10V dimming enables scene control for different activities: full output for basketball, 50% for yoga, 30% for events. DLC certified for utility rebates. Model your gymnasium layout free with LightSpec AI to verify uniformity and glare angles from all court positions.
