240 / 270 / 310 Watt Adjustable LED UFO High Bay | 34800 to 45000 Lumens | 4000K / 5000K Adjustable | 100-277V

Professional LED UFO High Bay for Commercial & Industrial Applications

This model is designed for applications where precise lighting control and exceptional durability are essential. With its wattage-adjustable design spanning 240 to 310 watts and lumen output ranging from 34,800 to 45,000, this UFO-style fixture delivers 145 lumens per watt efficiency while offering both 4000K and 5000K color temperature options. Built with die-cast aluminum housing and engineered to handle demanding conditions from -40°F to 113°F, this fixture provides reliable illumination backed by UL certification, DLC Premium status, and comprehensive surge protection.

Suitable Environments

• Manufacturing facilities requiring high-output overhead lighting with temperature flexibility
• Warehouses and distribution centers where consistent illumination across large areas is critical
• Retail spaces needing adjustable color temperature for merchandise display optimization
• Gymnasium and recreational facilities demanding durable, impact-resistant lighting solutions
• Agricultural buildings where extreme temperature tolerance and moisture resistance are required
• Automotive service bays requiring bright, adjustable lighting for detailed work

Metal Halide Replacement Benefits

• Replaces 400 to 1000 watt metal halide fixtures while consuming significantly less energy
• Eliminates warm-up periods and restrike delays common with traditional HID systems
• Reduces heat generation substantially compared to metal halide equivalents
• Provides instant full brightness without the gradual illumination ramp-up
• Delivers consistent color rendering throughout the entire 50,000-hour lifespan
• Eliminates frequent lamp replacements and ballast maintenance associated with HID technology

Performance & Safety

Engineered for high performance in demanding commercial environments, this fixture maximizes energy efficiency with its .90 power factor and minimal 20% total harmonic distortion. The 0-10V dimming capability allows operators to fine-tune lighting levels based on occupancy and task requirements, while the adjustable wattage feature provides installation flexibility without fixture replacement.

From a safety perspective, the IK10 impact rating and IP65 moisture protection ensure dependable operation in challenging conditions. Additionally, the 4kV surge protection safeguards against electrical disturbances, while the wide 100-277V input voltage accommodates various electrical systems without requiring additional transformers or specialized wiring.

For most installations, the 50,000-hour L70 lifespan significantly reduces maintenance interventions compared to traditional lighting systems. The motion sensor capability further optimizes energy use by automatically adjusting operation based on occupancy patterns, helping facilities reduce operational costs while maintaining adequate illumination levels.

Setup & Mounting

In practice, this fixture offers versatile installation options with standard eye-hook mounting, plus pendant and surface-mount alternatives to accommodate different ceiling configurations. The compact 14 x 11 inch profile and lightweight 11-pound construction simplify handling during installation, while the 5-foot power cord and 8-inch dimming lead provide adequate length for most electrical connections. The 110-degree beam angle with polycarbonate lens optics delivers uniform light distribution without requiring additional reflectors or diffusion accessories.
