400 Watt Round Explosion Proof LED Light | 56000 Lumens | Class 1 Div 2 | 5000K | 100V-277V or 277V-480V

Product Overview

This is a 400 watt round explosion proof LED light designed for hazardous and industrial environments. It delivers 56,000 lumens at 5000K color temperature and is built to replace 1000 watt metal halide fixtures.

The fixture is available in two voltage options: 100V-277V or 277V-480V. It features a tempered glass lens, copper free aluminum housing, and a gray finish. The standard beam angle is 120 degrees, with optional 40, 60, or 90 degree optics.

This light is rated for 50,000 hours (L70) and supports 1-10V dimming. It is designed for use in hazardous locations and carries multiple hazardous location certifications.

Mounting options include yoke or 3/4 inch NPT pendant. The fixture measures 18.9 by 15.5 inches and weighs 37.5 pounds.

Where This Product Fits Best

This explosion proof LED light is suitable for industrial sites where hazardous gases, vapors, or dusts are present. It is built for Class I Division 2, Class II Division 1 and 2, and Class III environments.

It is commonly used in oil and gas facilities, chemical plants, refineries, grain processing, and other locations requiring certified hazardous location lighting.

The IP66 rating allows installation in areas exposed to water, dust, or harsh weather. The fixture is also suitable for marine outside type environments as covered by UL 1598A.

With a 5000K daylight color temperature and high lumen output, it is intended for large spaces needing high visibility and uniform illumination.

Performance and Functional Considerations

This fixture outputs 56,000 lumens at 140 lumens per watt, providing high efficiency for demanding applications. It is designed to replace 1000 watt metal halide systems.

The 1-10V dimming capability allows for integration with compatible dimming controls. The fixture operates on either 100V-277V or 277V-480V, supporting a wide range of electrical systems.

Beam angle options (120, 90, 60, or 40 degrees) allow for adjustment of light distribution to suit different mounting heights and coverage needs. The tempered glass lens provides durability in hazardous environments.

The fixture maintains a power factor above 0.95 and total harmonic distortion below 10%. Surge protection is rated at 10kV.

Installation and Long-Term Use

Mounting options include yoke or 3/4 inch NPT pendant, supporting both ceiling and pendant installations. The fixture weighs 37.5 lbs and measures 18.9 by 15.5 inches, so ensure mounting structures can support the load.

The copper free aluminum housing resists corrosion in harsh and marine environments. The IP66 rating protects against dust and strong water jets, allowing use in wet or washdown areas.

The fixture operates in ambient temperatures from -40°F to 140°F. The 50,000 hour L70 lifespan supports long-term use with minimal maintenance.

All wiring and installation should follow hazardous location requirements as defined by the listed certifications.

How This Fixture Is Commonly Used

After installation, this explosion proof LED light provides consistent, high-output illumination in hazardous areas. The 5000K color temperature delivers a daylight-like appearance for improved visibility.

Beam angle selection allows you to tailor the light spread for your space. Wider angles are used for general area lighting, while narrower options focus light for higher mounting or task areas.

The fixture supports 1-10V dimming, so you can connect it to compatible dimming systems for adjustable output as needed. The robust housing and lens require minimal attention beyond routine inspection.

Once installed, the fixture is designed to operate reliably in environments with exposure to dust, water, and corrosive elements, reducing the need for frequent replacement or servicing.
