80 Watt Square Explosion Proof LED Light | 11200 Lumens | Class 1 Div 1 | Class 2 Div 1 | 5000K | 100V-277V or 277V-480V

Product Overview

This 80 watt square explosion proof LED fixture delivers 11,200 lumens at 140 lumens per watt, serving as a direct replacement for 250 watt metal halide systems in hazardous classified areas. The fixture operates across two voltage ranges: 100V-277V or 277V-480V, with a 5000K color temperature and 70+ CRI output.

Construction uses copper free aluminum housing with a tempered glass lens. The fixture measures 11.6 x 11.6 x 9.57 inches and weighs 27 pounds. A gray finish is standard across all configurations.

Mounting options include yoke mount or 3/4 inch NPT pendant. The standard beam angle is 120 degrees, with optional 40, 60, or 90 degree optics available for applications requiring narrower distribution patterns.

Where This Product Fits Best

This fixture is certified for use in Class I Division 1 and Division 2 locations where flammable gases, vapors, or liquids may be present. Specific group ratings include Groups C and D for Division 1, and Groups A, B, C, and D for Division 2. These ratings cover environments with atmospheres containing acetylene, hydrogen, ethylene, propane, and similar substances.

Class II Division 1 certification covers Groups E, F, and G, addressing locations with combustible metal dusts, carbon-based dusts, and grain or fiber particulates. Class II Division 2 covers Groups F and G. Class III certification extends coverage to areas where easily ignitable fibers or flyings are handled or stored.

The UL 1598 wet location rating and UL 1598A marine outside type certification allow installation in exposed outdoor industrial areas and marine deck or offshore platform applications. ABS certification supports use in shipboard and maritime environments.

Performance and Functional Considerations

At 80 watts input and 11,200 lumens output, this fixture achieves 140 lumens per watt efficacy. The 50,000 hour L70 lifespan represents the point at which output is projected to remain at or above 70 percent of initial lumens under rated operating conditions.

The operating temperature range spans -22 degrees F to 122 degrees F, which accommodates cold storage entry zones, outdoor platforms, and process areas with elevated ambient heat. Power factor exceeds 0.95 and total harmonic distortion remains below 10 percent, supporting stable operation on facility electrical systems.

The fixture includes 0-10V dimming capability for integration with building automation or manual dimming controls. Surge protection is rated at 10kV.

Installation and Long-Term Use

Two mounting methods are supported: yoke mount for ceiling or structural attachment, and 3/4 inch NPT pendant for conduit-hung installations typical in hazardous classified areas. The 27 pound weight requires appropriate structural support and rigging during installation.

IP66 rating allows the fixture to withstand high-pressure water jets and complete dust ingress protection, which is relevant for washdown areas and dusty industrial environments. IK10 impact rating protects against direct physical contact equivalent to heavy tool drops or incidental equipment strikes.

The tempered glass lens maintains optical clarity under harsh conditions and resists thermal shock better than standard glass or polycarbonate alternatives. Copper free aluminum housing eliminates corrosion risks in environments where copper incompatibility is a concern.

How This Fixture Is Commonly Used

Facilities use this fixture in paint spray booths, fuel transfer stations, grain handling operations, chemical processing areas, and similar spaces where hazardous atmosphere classifications mandate explosion proof equipment. The dual voltage availability allows the same fixture model to serve both standard 120V-277V distribution systems and higher voltage 277V-480V infrastructure common in heavy industrial plants.

The 120 degree standard beam angle provides broad coverage for general area lighting. When narrower distribution is needed for aisle lighting, task areas, or higher mounting heights, the 40, 60, or 90 degree optional optics concentrate output into tighter patterns. Beam angle selection is typically determined during project specification based on mounting height and required light levels at the work plane.

The 0-10V dimming input allows facilities to reduce output during unoccupied periods or integrate with plant-wide lighting control systems. Dimming also provides flexibility for areas where full output may exceed requirements during certain shifts or operations.

Safety, Certifications, and Warranty

This fixture is UL 844 listed for hazardous locations and ETL listed. UL 1598 wet location suitability and UL 1598A marine outside type certification are included. ABS certification supports maritime applications.

The fixture is rebate eligible. We provide a 5 year warranty on this product.
