450 Watt LED High Temperature Light | 58500 Lumens | 5000K | 100V-277V or 277V-480V | Rated to 176F

Product Overview

This 50 watt LED high temperature fixture delivers 6,500 lumens at 5000K with a 130 lumens-per-watt efficacy. It serves as a direct replacement for 175 watt metal halide systems in environments where standard fixtures cannot operate reliably.

The defining characteristic of this fixture is its operating temperature range of -40°F to 176°F. This allows installation in foundries, bakeries, boiler rooms, industrial kitchens, and other spaces where ambient heat renders conventional LED high bays unsuitable.

Two voltage configurations are available: 100V-277V and 277V-480V. The fixture operates on 50/60 Hz systems with a power factor of .95 and total harmonic distortion under 20%.

Where This Product Fits Best

This fixture is built for industrial environments with sustained high ambient temperatures. Applications include heat treatment facilities, forge shops, glass manufacturing areas, commercial laundries, and process areas adjacent to furnaces or ovens. The 176°F upper limit accommodates conditions that would cause thermal shutdown or accelerated failure in standard LED fixtures.

The IP66 rating allows use in spaces with heavy washdown, airborne particulates, or direct water spray. The IK10 impact rating protects the fixture in environments with overhead crane activity, material handling equipment, or other mechanical hazards.

At 6,500 lumens, this fixture suits task-specific lighting over workstations, equipment, or process lines rather than broad area coverage across large warehouse bays.

Performance and Functional Considerations

The 110-degree beam angle is standard, with optional optics available in 30-degree, 90-degree, and 150-degree configurations. The 30-degree optic concentrates output for higher mounting heights or narrow task areas. The 150-degree optic spreads light for lower ceilings or wider coverage.

The polycarbonate lens resists impact and maintains transmission in harsh operating conditions. Color rendering index is 70+, suitable for industrial work where color accuracy is secondary to visibility and durability.

Rated lifespan is 100,000 hours at L70, meaning the fixture retains 70% of initial output at that point. This fixture does not support dimming.

Installation and Long-Term Use

Mounting options include eye-hook and trunnion configurations. The eye-hook allows pendant mounting from chains or cables. The trunnion mount provides direct attachment to structure with adjustable aim.

The fixture measures 12.1 x 14.4 x 9.6 inches and weighs 17.2 pounds. The die-cast aluminum housing dissipates heat effectively even under sustained high-temperature operation. Fixture color is gray.

Built-in 12kV surge protection guards against transient voltage spikes common in industrial electrical environments. This level of protection reduces the likelihood of driver failure from grid instability or equipment switching.

How This Fixture Is Commonly Used

Facility operators install this fixture in locations where heat accumulation has caused repeated failures with standard LED equipment. The 176°F operating limit means it continues running in conditions that would trigger thermal protection shutdowns in conventional fixtures.

The beam angle selection allows the fixture to be matched to the task. Narrow optics work well over specific machinery or inspection stations. Wider optics suit general illumination in processing areas with lower ceiling heights.

With both low-voltage and high-voltage input options, the fixture connects directly to existing electrical infrastructure without requiring step-down transformers or rewiring.

Safety, Certifications, and Warranty

This fixture is ETL listed. The IP66 rating means the fixture is sealed against dust ingress and protected against powerful water jets from any direction. The IK10 rating means the fixture withstands significant mechanical impact.

We provide a 5-year warranty on this fixture.
