250 Watt Round Explosion Proof LED Light | 35000 Lumens | Class 1 Div 1 | Class 2 Div 1 | 5000K | 100-277V or 277-480V

Product Overview

This 250 watt round explosion proof LED fixture delivers 35,000 lumens at 140 lumens per watt with a 5000K color temperature. It replaces 400 watt metal halide fixtures in hazardous locations classified under UL 844. The fixture is available in two voltage configurations: 100-277V or 277-480V, both operating at 50-60Hz.

The housing is constructed from copper-free aluminum with a tempered glass lens and carries a gray finish. Dimensions measure 16 inches in diameter by 13.5 inches in height, with a weight of 39 pounds. The fixture includes 1-10V dimming capability and a standard 120-degree beam angle.

Mounting options include yoke mount or 3/4 inch NPT pendant mount. The fixture is rated for a 50,000 hour lifespan at L70 and carries a 5-year warranty.

Where This Product Fits Best

This fixture is classified for Class I, Division 1, Groups C and D, as well as Class I, Division 2, Groups A, B, C, and D. It also covers Class II, Division 1, Groups E, F, and G, Class II, Division 2, Groups F and G, and Class III locations. These classifications address environments with ignitable fibers, combustible dust, and flammable gases or vapors present under normal or abnormal conditions.

The UL 1598 wet location rating and UL 1598A marine outside type listing support installation in outdoor industrial environments and marine applications. ABS certification is also included. The operating temperature range spans -22 degrees F to 122 degrees F.

ATEX and IECEx markings are provided for facilities requiring compliance with international hazardous location standards. ATEX marking includes II 2 G D, Ex db IIB T6 through T3 Gb, and Ex tb IIIC T80 degrees C through T195 degrees C Db. IECEx marking mirrors the ATEX designations.

Performance and Functional Considerations

At 35,000 lumens and 140 lumens per watt, this fixture provides high output with efficient energy use relative to the 400 watt metal halide systems it replaces. The 5000K color temperature produces a cool white light suitable for task visibility in industrial environments. CRI is rated at 70 or higher.

The 1-10V dimming interface allows integration with compatible control systems where output reduction is needed. Power factor exceeds 0.95 and total harmonic distortion remains below 10 percent, supporting stable operation on facility electrical systems.

Surge protection is rated at 10kV. The 120-degree beam angle provides broad coverage from the tempered glass optic.

Installation and Long-Term Use

The fixture mounts via yoke or 3/4 inch NPT pendant, supporting ceiling-hung or structure-mounted configurations in hazardous areas. At 39 pounds, structural support must accommodate the weight plus any vibration or environmental loading present at the installation site.

IP66 rating means the fixture is protected against powerful water jets and complete dust ingress. IK10 rating means the housing withstands significant physical impact. These ratings support installations in wash-down areas, dusty processing environments, and locations subject to incidental contact.

The copper-free aluminum housing resists corrosion in environments where copper can degrade or create hazardous conditions. The 50,000 hour rated lifespan at L70 reduces lamp change frequency compared to metal halide systems.

How This Fixture Is Commonly Used

Facilities use this fixture in refineries, chemical processing plants, grain handling operations, paint booths, and other spaces where flammable gases, vapors, or combustible dust may be present. The Class I and Class II division ratings determine where the fixture can be legally installed based on the hazardous material classification of the space.

The 1-10V dimming input allows operators to reduce output when full brightness is unnecessary, typically controlled through a building automation system or manual dimmer. The two voltage options address both standard commercial service and higher voltage industrial distribution without requiring external transformers.

The yoke mount works well for ceiling or beam attachment where aiming adjustment is needed. The NPT pendant option suits conduit runs from junction boxes in ceiling or structure penetrations. Both methods maintain the fixture''s sealed integrity required for hazardous location compliance.

Safety, Certifications, and Warranty

This fixture is UL 844 listed for hazardous locations and UL 1598 listed for wet locations. It is UL 1598A listed as marine outside type and carries ABS certification. The fixture is ETL listed and rebate eligible.

ATEX and IECEx certifications are included for applications requiring compliance with those international hazardous area standards. The temperature class ratings under ATEX and IECEx range from T6 through T3 for gas environments and T80 degrees C through T195 degrees C for dust environments.

We provide a 5-year warranty on this fixture.
