300 Watt LED High Temperature Light | 45000 Lumens | 5000K | 100-277V | Rated to 212F

Product Overview

This 300 watt LED high temperature fixture delivers 45,000 lumens at 5000K and operates across an ambient temperature range of -40°F to 212°F. The fixture replaces 1000 watt metal halide systems and is built with an aluminum alloy housing and oversized heat sink designed for sustained operation in extreme thermal environments.

The fixture accepts 100-277V input at 50/60 Hz, outputs 150 lumens per watt, and carries a CRI of 70+. A polycarbonate lens protects the optics. Standard beam angle is 90 degrees, with optional 25, 40, or 60 degree optics available. The fixture measures 22 x 19 x 4 inches and weighs 38 pounds.

Where This Product Fits Best

This fixture is intended for locations where ambient temperatures exceed the limits of standard LED high bays. Foundries, forges, glass manufacturing, heat treat facilities, industrial bakeries, and areas near boilers or kilns are typical applications. The 212°F upper rating allows installation in radiant heat zones that would damage conventional LED fixtures.

The -40°F lower rating also supports cold storage, freezer warehouses, and outdoor installations in extreme winter climates. IP66 ingress protection allows use in washdown areas and locations exposed to heavy dust or water spray.

Performance and Functional Considerations

At 45,000 lumens, this fixture provides output comparable to a 1000 watt metal halide lamp while drawing 300 watts. The 150 lumens per watt efficacy reflects performance at rated conditions. Power factor exceeds 0.95 and total harmonic distortion is under 15 percent.

The 90 degree standard beam angle provides broad coverage for open areas. The optional 25, 40, or 60 degree optics concentrate output for higher mounting heights or narrower target zones. Beam angle selection affects light distribution and uniformity at working plane height.

This fixture is non-dimmable. Applications requiring dimming control will need a different product.

Installation and Long-Term Use

Mounting options include eye-hook, pendant, and trunnion configurations. The 38-pound weight and 22 x 19 inch footprint require appropriate structural support. The aluminum alloy housing with integrated heat sink is designed to dissipate thermal load under continuous high-temperature operation.

The fixture includes 6kV surge protection. Rated lifespan is 100,000 hours at L70, meaning the fixture is expected to retain at least 70 percent of initial lumen output at that point. The gray finish is standard.

How This Fixture Is Commonly Used

Once installed, this fixture operates without user adjustment in most applications. Facilities with varying task zones may select different beam angle optics at the time of installation to match mounting height and coverage needs. The 90 degree standard optic works well for general area lighting, while narrower optics are used when fixtures are mounted higher or when concentrated light is needed on specific work areas.

In high-heat environments, the fixture continues operating where standard high bays would shut down or fail prematurely. Maintenance teams working in foundries, glass plants, or near industrial ovens rely on fixtures rated for these conditions to avoid repeated lamp or fixture replacement caused by thermal stress.

Safety, Certifications, and Warranty

This fixture is ETL listed. IP66 rated, the fixture is protected against powerful water jets and complete dust ingress. Surge protection is rated at 6kV.

We provide a 5-year warranty on this fixture.
