170 Watt LED High Bay Linear | 23120 Lumens | 4000K / 5000K Adjustable | 277-480V | 2 Foot

Product Overview

This adjustable UFO high bay delivers 44,900 to 79,100 lumens across three wattage settings: 300W, 400W, and 500W. Field-selectable output and color temperature allow a single fixture to serve multiple mounting heights and light level requirements without fixture substitution.

At 155 lumens per watt, this fixture replaces 1500W to 2000W metal halide systems. The 100-277V input range covers standard commercial and industrial electrical configurations. Color temperature switches between 4000K and 5000K at the fixture.

Construction includes an aluminum alloy housing with a polycarbonate lens. The fixture measures 17.7 inches in diameter and 10.6 inches in height, with a weight of 14.5 pounds. Standard finish is black.

Where This Product Fits Best

This high bay is built for spaces with high ceilings and demanding environmental conditions. The IP65 rating allows installation in areas exposed to dust, debris, and water spray from cleaning or condensation. IK08 impact resistance handles incidental contact from equipment or material handling operations.

The operating temperature range of -22°F to 122°F supports cold storage entries, unconditioned warehouses, and facilities with significant seasonal temperature swings. The 6kV surge protection addresses electrical noise common in buildings with heavy motor loads, compressors, or industrial switching equipment.

Typical deployment includes warehouse aisles, manufacturing floors, distribution staging areas, and other large open spaces where legacy metal halide systems are being replaced or upgraded.

Performance and Functional Considerations

Lumen output spans a wide range depending on the wattage selected. At 300W, the fixture produces 44,900 lumens. At 400W, output increases to 62,000 lumens. The 500W setting delivers 79,100 lumens. These values allow the same fixture to address different mounting heights or foot-candle targets.

The 90-degree beam angle provides broad coverage suitable for general area lighting. CRI is rated at 80+, which supports accurate color perception for task work, product inspection, and safety marking visibility.

Dimming is available via 0-10V protocol, allowing integration with building management systems or standalone dimmers. Power factor is 0.95 with THD at 20%, meeting typical utility and facility electrical quality standards.

Installation and Long-Term Use

Mounting uses an eye-hook configuration, compatible with standard pendant or chain suspension hardware. The 14.5-pound fixture weight is manageable for single-technician installation in most lift or scaffold scenarios.

Wattage and color temperature are adjusted at the fixture before or after installation. This allows output tuning based on actual site conditions observed during commissioning. The 100-277V universal voltage input eliminates transformer requirements for most North American commercial and industrial circuits.

Rated lifespan is 170,000 hours at L70, reducing lamp replacement cycles significantly compared to metal halide. The five-year warranty covers defects during the initial operational period.

How This Fixture Is Commonly Used

The adjustable wattage allows you to tune output based on what you observe during installation. If a space runs brighter than expected at 500W, dropping to 400W or 300W reduces energy consumption without replacing hardware. If an aisle runs darker at lower settings, increasing wattage addresses the shortfall immediately.

The color temperature switch gives you control over the light appearance. 5000K produces a cooler, more daylight-like tone often used in production and inspection areas. 4000K provides a slightly warmer tone that works well in general warehouse and storage environments.

Once installed, the 0-10V dimming connection lets you integrate the fixture into scheduled or occupancy-based control schemes if your facility uses a compatible system. This supports energy management without requiring fixture-level reprogramming.
