100 / 120 / 150 Watt Adjustable LED UFO High Bay | 15000 to 22500 Lumens | 4000K / 5000K Adjustable | 100-277V

High-Performance Adjustable LED High Bay

Built for environments where flexibility and performance matter most, this adjustable LED UFO high bay delivers exceptional lighting control with field-selectable wattage and color temperature options. Engineered to handle demanding conditions in warehouses, manufacturing facilities, and distribution centers, this fixture provides up to 22,500 lumens of consistent illumination while maintaining an impressive 150 lumens per watt efficiency.

What makes this fixture valuable for buyers is its triple adjustability - wattage can be set to 100, 120, or 150 watts, color temperature adjusts between 4000K and 5000K, and the integrated motion sensor capability provides additional energy savings. With its die-cast aluminum housing and IP65 rating, this high bay withstands harsh industrial environments while delivering reliable performance over its 50,000-hour lifespan.

Comparison to Legacy Lighting

When upgrading from metal halide systems, this LED high bay offers substantial improvements in energy efficiency, light quality, and maintenance requirements. By comparison, traditional 250W and 400W metal halide fixtures consume significantly more energy while producing less consistent light output and requiring frequent lamp replacements.

• Replaces 250W or 400W metal halide fixtures with up to 70% energy reduction
• Eliminates warm-up time and restrike delays common with HID lighting
• Provides consistent color rendering with 80+ CRI versus declining output of aging metal halide
• Reduces maintenance costs through 50,000-hour rated life versus 15,000-hour metal halide lamps

Installation & Mounting

For most installations, this fixture offers versatile mounting options to accommodate different ceiling configurations and height requirements. The standard eye-hook mounting provides easy pendant installation, while the optional surface mount capability allows for direct ceiling attachment in lower-profile applications.

Benefits of This Fixture

Energy Savings & ROI

From a cost standpoint, the adjustable wattage feature allows facility managers to optimize energy consumption based on specific area requirements. The 150 lumens per watt efficiency, combined with 0-10V dimming capability and motion sensor compatibility, maximizes energy savings while maintaining adequate illumination levels for safety and productivity.

Light Quality

Designed to deliver superior visual performance, the selectable 4000K or 5000K color temperature options provide optimal light quality for different applications. The 80+ CRI ensures accurate color rendering, while the polycarbonate lens system distributes light evenly across the 120-degree beam pattern without harsh shadows or glare.

Maintenance Reduction

In practice, the 50,000-hour rated life significantly reduces maintenance interventions compared to traditional lighting systems. The robust die-cast aluminum construction and sealed design minimize component degradation, while the fanless thermal management system eliminates moving parts that could require service.

Safety

From a safety perspective, the instant-on LED technology eliminates the safety risks associated with metal halide warm-up periods. Additionally, the low operating temperature and surge protection features reduce fire hazards, while the motion sensor capability ensures adequate lighting when personnel enter work areas.
