155 / 180 / 210 Wattage Adjustable High Bay Linear | 22880 to 31000 Lumens | 4000K / 5000K Adjustable | 100-277V or 277-480V | 1 Foot 2 Inches

Product Overview

This 150 watt LED UFO high bay delivers 24,000 lumens at 5000K with a CRI of 80+. The fixture replaces 400 watt metal halide systems and operates at 160 lumens per watt. It is available in two voltage configurations: 100-277V or 277-480V.

The fixture measures 15.75 x 7.9 inches, weighs 14.4 pounds, and includes a 4-foot cord. A 120-degree beam angle with polycarbonate lens optics provides broad light distribution from a single mounting point. The housing is die-cast aluminum with a black finish.

Where This Product Fits Best

This high bay is sized for facilities currently running 400 watt metal halide fixtures. The 24,000 lumen output at 5000K suits warehouse aisles, manufacturing floors, and distribution staging areas where consistent daylight-tone illumination supports visual tasks.

The IP65 rating allows installation in spaces exposed to dust accumulation and occasional washdown. The IK08 rating provides resistance to moderate mechanical impact, which matters in active loading docks or production environments where equipment movement creates risk of incidental contact.

Operating temperature range spans -22°F to 122°F, making this fixture appropriate for cold storage entries, unconditioned warehouse space, and facilities with seasonal temperature swings.

Performance and Functional Considerations

At 160 lumens per watt, this fixture produces its rated output with relatively low heat load compared to legacy metal halide systems. The 50,000-hour L70 lifespan establishes expected useful life before output drops below 70% of initial lumens.

The 1-10V dimming interface allows integration with external dimming controls where reduced output is needed during off-peak hours or to match daylight contribution. Power factor is rated at .93 with THD at 20% maximum, which supports stable operation on commercial electrical systems.

Frequency compatibility covers both 50 Hz and 60 Hz service, accommodating standard North American electrical systems and international installations where applicable.

Installation and Long-Term Use

The fixture mounts via an eye-hook, which allows direct suspension from chains, cables, or pendant hardware. The 4-foot cord provides working length for connection to junction boxes positioned above the mounting point.

At 14.4 pounds, this unit requires secure overhead attachment. Existing metal halide hook mounts may support direct reuse depending on structural condition and load rating. Die-cast aluminum housing dissipates heat effectively and resists corrosion in environments with moisture exposure.

The IP65 rating means the fixture can be hosed off during facility cleaning without water ingress. The IK08 impact rating protects against contact equivalent to incidental bumps from ladders or equipment, though direct high-force strikes should be avoided.

How This Fixture Is Commonly Used

Facilities replacing aging metal halide high bays often use this fixture to reduce maintenance frequency while maintaining equivalent or improved light levels. The 120-degree beam angle spreads light broadly, which works well in open floor layouts without tall racking that would block distribution.

The 1-10V dimming capability allows operators to reduce output when full brightness is unnecessary. This is typically connected to a wall-mounted dimmer or building automation system. The 5000K color temperature provides a cool white appearance that supports color differentiation in picking, packing, and inspection tasks.

Safety, Certifications, and Warranty

This fixture is ETL listed and rebate eligible. The IP65 and IK08 ratings establish environmental and impact protection limits for installation planning.

We provide a 5-year warranty on this product.
