75 Watt Round Explosion Proof LED Light | 10500 Lumens | Class 1 Div 2 | 5000K | 100-277V

Product Overview

This 75 watt round explosion proof LED fixture delivers 10,500 lumens at 140 lumens per watt with a 5000K color temperature. It operates on 100-277V input at 50-60Hz and replaces 400 watt metal halide systems. The 120-degree beam angle uses a tempered glass lens, and the fixture supports 1-10V dimming.

The powder coated aluminum housing weighs 13 pounds and carries an IP66 rating for protection against dust ingress and high-pressure water jets. The IK08 rating allows the fixture to withstand moderate mechanical impact. Built-in 10kV surge protection is standard. The fixture ships without a cord.

Rated lifespan is 150,000 hours at L70. The fixture is UL listed and carries CSA, ATEX, and IECEX certifications. We back this product with a 5-year warranty.

Where This Product Fits Best

This fixture is classified for Class 1 Division 2 Groups A, B, C, and D environments where flammable gases or vapors may be present under abnormal conditions. It is also rated for Class 2 Division 1 Groups E, F, and G where combustible dust is present during normal operation, and Class 2 Division 2 Groups F and G where dust is present only under abnormal conditions. Class 3 locations with ignitable fibers or flyings are also covered.

Zone classifications include Class 1 Zone 2 Group IIC, Zone 20, Zone 21, and Zone 22. The UL844 wet location rating per UL 1598 and UL 1598A allows installation where direct water exposure occurs. These classifications make the fixture appropriate for chemical processing areas, grain handling facilities, paint booths, fuel dispensing areas, and similar hazardous locations.

The IP66 rating supports installations exposed to dust-laden air and direct water spray. Facilities with washdown protocols or outdoor mounting in exposed conditions can use this fixture without secondary enclosures.

Performance and Functional Considerations

At 10,500 lumens from 75 watts, this fixture provides equivalent output to 400 watt metal halide while drawing significantly less power. The 140 lumens per watt efficacy reflects current LED performance standards for hazardous location fixtures. CRI is rated at 70 or higher.

The 5000K color temperature produces a daylight-balanced white light suitable for task visibility in industrial environments. The 120-degree beam angle from the tempered glass lens provides broad coverage appropriate for general area illumination rather than focused task lighting.

Power factor exceeds 0.90 and total harmonic distortion remains below 10 percent, supporting stable operation on facility electrical systems. The 100-277V input range accommodates standard commercial and industrial voltage configurations without external transformers.

Installation and Long-Term Use

Mounting options include surface, wall, trunnion, and 3/4-inch NPT pendant configurations. The fixture does not include a cord, so field wiring is required at installation. At 13 pounds, the fixture requires secure mounting hardware appropriate for the selected configuration and structural substrate.

The powder coated aluminum housing resists corrosion in wet and chemically active environments. The IK08 impact rating allows the fixture to tolerate bumps from equipment or debris without housing or lens damage. The tempered glass lens maintains integrity under thermal cycling and mechanical stress.

With 10kV surge protection built in, the fixture handles transient voltage events typical in industrial electrical systems. The 150,000-hour rated lifespan at L70 supports extended service intervals before lumen depreciation affects light levels. The gray housing color is standard.

How This Fixture Is Commonly Used

Facilities replacing 400 watt metal halide systems in hazardous locations use this fixture to maintain equivalent light output while reducing energy consumption. The 1-10V dimming capability allows output adjustment when connected to compatible controls, which some facilities use for daylight harvesting or reduced output during low-activity periods.

The multiple mounting options allow installation in ceiling-mount, wall-mount, or pendant configurations depending on the structural conditions and lighting geometry required. Pendant mounting with the 3/4-inch NPT connection is common in high-ceiling industrial bays where fixtures need to hang below obstructions or ductwork.

The combination of wet location rating and hazardous location classifications means this fixture serves dual-purpose in facilities where both moisture exposure and combustible atmosphere risks exist in the same space. Maintenance crews work with one fixture type across these overlapping conditions.

Safety, Certifications, and Warranty

This fixture is UL listed under UL844 for hazardous locations and UL 1598/UL 1598A for wet locations. It carries CSA certification for Canadian installations and ATEX and IECEX certifications for international hazardous location compliance.

The classified groups and zones cover a broad range of hazardous atmospheres including gases, vapors, combustible dusts, and ignitable fibers. Specific classifications are Class 1 Division 2 Groups A, B, C, D; Class 2 Division 1 Groups E, F, G; Class 2 Division 2 Groups F, G; Class 3; Class 1 Zone 2 Group IIC; Zone 20; Zone 21; and Zone 22.

We provide a 5-year warranty on this fixture.
