150 Watt Round High Temperature Explosion Proof LED Light | 15000 Lumens | Class 1 Div 2 | Class 2 Div 2 | 5000K | 120V | Rated to 176F

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 aluminum alloy housing incorporates a large heat sink designed to manage thermal load in environments where standard LED fixtures would fail or derate.

At 150 lumens per watt, this fixture replaces 1000 watt metal halide systems. The polycarbonate lens is available with a standard 90° beam angle or optional 25°, 40°, or 60° distributions. Voltage input spans 100V-277V at 50/60 Hz with a power factor above 0.95 and THD below 15%.

The fixture measures 22 x 19 x 4 inches and weighs 38 pounds. It is ETL listed and carries an IP66 rating with 6kV surge protection. Mounting options include eye-hook, pendant, and trunnion configurations. The fixture ships in gray.

Where This Product Fits Best

This fixture is built for environments where ambient temperatures reach levels that exceed the operating limits of conventional LED high bays. Applications include foundries, steel mills, glass manufacturing, heat treatment facilities, boiler rooms, and industrial ovens where radiant or ambient heat creates sustained high-temperature exposure at fixture level.

The -40°F to 212°F operating range also makes this fixture suitable for cold storage and freezer environments where extreme low temperatures are a concern. Standard LED drivers and housings can struggle in these conditions, leading to premature failure or inconsistent light output.

The IP66 rating supports installation in washdown areas and spaces with high humidity, steam, or airborne particulates. The 6kV surge protection addresses electrical environments with unstable power or inductive load switching.

Performance and Functional Considerations

The 45,000 lumen output at 300 watts provides a direct replacement path for 1000 watt metal halide fixtures. The 5000K color temperature produces a neutral daylight appearance suited to task-intensive and inspection-critical work areas. CRI is rated at 70+.

The standard 90° beam angle covers broad areas from moderate mounting heights. Optional 25°, 40°, and 60° optics are available for applications requiring more concentrated distribution, such as aisle lighting or targeted task illumination in high-bay environments.

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

Installation and Long-Term Use

Mounting is supported via eye-hook, pendant, or trunnion configurations. The trunnion option allows angle adjustment for directional aiming. At 38 pounds, structural support and fastener selection should account for fixture weight and any vibration present in the environment.

The 100V-277V input range accommodates most commercial and industrial electrical systems without the need for external transformers. Power factor above 0.95 and THD below 15% support stable operation on shared circuits and reduce harmonic interference with other equipment.

The aluminum alloy housing and large heat sink are designed to dissipate heat effectively even under sustained high-temperature exposure. The IP66 rating allows direct exposure to high-pressure water jets and dust ingress, supporting routine washdown cleaning without requiring fixture removal or protective covering.

How This Fixture Is Commonly Used

Facilities operating near the upper end of the temperature range typically position this fixture in locations where radiant heat from furnaces, kilns, or process equipment would damage standard LED high bays. The large heat sink allows the fixture to remain in continuous operation without thermal throttling or early driver failure.

In cold storage applications, the fixture is used where temperatures remain below the minimum threshold of conventional LED drivers. The -40°F lower limit allows installation in blast freezers and cold rooms without startup delays or reduced output.

The beam angle options allow installers to match light distribution to space geometry. The 90° standard distribution suits open areas, while the narrower optional optics concentrate output for aisle or rack-lighting configurations. Optic selection is determined at time of order based on layout requirements.

Safety, Certifications, and Warranty

This fixture is ETL listed. The IP66 rating allows installation in environments with direct water exposure and airborne dust. Surge protection is rated at 6kV.

We provide a 5-year warranty on this fixture.
