High-Performance Adjustable LED High Bay Solution
This adjustable UFO high bay fixture delivers exceptional versatility with selectable wattage options from 250W to 500W and dual color temperature settings. Engineered to handle demanding industrial conditions while providing superior light output up to 76,800 lumens, this fixture offers the flexibility to optimize performance for specific application requirements without maintaining multiple SKUs.
Legacy Replacement Comparison
When upgrading from metal halide systems rated at 1500W or 2000W, this LED fixture delivers equivalent illumination while consuming up to 75% less energy. Unlike traditional HID lighting that requires lengthy warm-up periods and frequent lamp changes, this solution provides instant-on capability and maintains consistent light output throughout its 150,000-hour lifespan. The 155 lumens per watt efficiency significantly outperforms metal halide alternatives that typically achieve only 70-90 lumens per watt.
Performance Benefits
Energy Efficiency
Built with advanced LED technology achieving 155 lumens per watt, this fixture maximizes energy savings while maintaining superior illumination levels. The high power factor of 0.95 ensures efficient power utilization, while the adjustable wattage feature allows operators to fine-tune energy consumption based on specific lighting requirements without compromising performance.
Light Quality
Offers reliable color rendering with 80+ CRI and selectable color temperatures of 4000K or 5000K to match facility needs. The polycarbonate lens system distributes light evenly across a 90-degree beam angle, eliminating hot spots and shadows common in traditional high bay installations. Additionally, the 0-10V dimming capability provides precise light level control for enhanced operational flexibility.
Longevity
Designed to deliver 150,000 hours of L70 performance, this fixture reduces maintenance costs and downtime significantly compared to metal halide systems that typically require lamp replacement every 10,000-15,000 hours. The aluminum alloy housing and robust thermal management system ensure consistent operation across the fixture's extended lifespan.
