310 Watt LED UFO High Bay | 45000 Lumens | 5000K | 277-480V

High-Output Industrial Lighting Solution

For facilities that require powerful, efficient illumination across large areas, this 310-watt LED UFO high bay delivers exceptional performance with 45,000 lumens of bright 5000K daylight. Built for environments where consistent visibility is critical, the fixture achieves 145 lumens per watt efficiency while operating reliably across demanding temperature ranges from -40°F to 113°F. What makes this fixture valuable for buyers is its die-cast aluminum construction and IP65/IK10 ratings that ensure dependable operation in harsh industrial conditions.

Replacing Older Lighting Systems

When upgrading from metal halide systems, this LED high bay provides a direct replacement for 1000 to 1500-watt metal halide fixtures while consuming significantly less power. Unlike traditional lighting options, this fixture eliminates warm-up delays and provides instant full brightness with superior color rendering at 80+ CRI.

• Reduces energy consumption by up to 70% compared to equivalent metal halide output
• Eliminates lamp replacement costs with 50,000-hour L70 lifespan
• Provides consistent light output without the gradual degradation of HID systems
• Offers 0-10V dimming capability not available with most legacy fixtures

Mounting, Setup & Controls

From an installation standpoint, the fixture supports multiple mounting configurations including standard eye-hook suspension, pendant mounting, or direct surface mounting to accommodate various ceiling heights and structural requirements. The 5-foot power cord and 8-inch dimming cord provide adequate reach for most installations, while the 277-480V input voltage works with standard commercial electrical systems operating at 50/60 Hz with excellent power factor performance at .90.

Operational Benefits

Energy Efficiency

With its 145 lumens per watt efficiency and low 20% maximum THD, this fixture optimizes energy use while maintaining clean power draw characteristics. The high power factor of .90 reduces demand charges and improves overall electrical system efficiency in commercial installations.

Reliability & Durability

Built with die-cast aluminum housing and engineered for high performance in challenging environments, the fixture's IP65 and IK10 ratings ensure protection against dust, moisture, and mechanical impact. Additionally, the wide operating temperature range and 4kV surge protection strengthen safety through robust electrical and environmental protection.

Maintenance Reduction

The 50,000-hour L70 lifespan significantly reduces downtime thanks to extended replacement intervals compared to traditional lighting. Equally important, the solid-state LED technology eliminates the frequent lamp changes and ballast replacements associated with metal halide systems, while the compact 13.8 x 10.9-inch profile and lightweight 13-pound construction simplify any necessary maintenance procedures.
