120 Watt Explosion Proof 2x4 Low Profile Linear LED Light | 16800 Lumens | Class 1 Div 2 | Class 2 Div 2 | 5000K | 100-277V

Product Overview

This 120 watt explosion proof 2x4 low profile linear LED light delivers 16,800 lumens at 5000K color temperature, designed for hazardous location classifications including Class 1 Division 2 Groups A, B, C, D, Class 2 Division 1 Groups F, G, and Class 3 environments. The fixture replaces 400 watt metal halide systems while operating at 140 lumens per watt efficiency.

The unit measures 49 x 23 x 3.7 inches and weighs 88 pounds. It operates on 100-277V input at 50-60Hz with a power factor greater than 0.95 and THD below 10 percent. A polycarbonate lens provides a 120-degree beam angle across the fixture''s output area.

Construction includes IP66 and IK09 ratings with an operating temperature range of -22°F to 122°F. The fixture supports 1-10V dimming and carries UL 844 listing for hazardous locations along with NSF rating. LED Lighting Supply backs this fixture with a 5-year warranty.

Where This Product Fits Best

This fixture is built for spaces classified under UL 844 hazardous location requirements. Class 1 Division 2 coverage addresses areas where flammable gases or vapors from Groups A, B, C, and D may be present under abnormal conditions. Class 2 Division 1 Groups F and G coverage applies to locations with combustible dust present during normal operations. Class 3 rating covers areas with ignitable fibers or flyings.

The low profile 2x4 form factor fits ceiling grid layouts and confined overhead spaces where traditional explosion proof fixtures with deeper housings cannot be accommodated. At 3.7 inches in depth, this fixture clears obstructions in spaces with limited plenum clearance or structural constraints.

The IP66 rating means the fixture is protected against high-pressure water jets and complete dust ingress, suitable for washdown areas and dusty processing environments. The IK09 rating provides resistance to mechanical impact equivalent to a 5-kilogram mass dropped from 200mm, handling incidental contact from equipment or materials handling.

Performance and Functional Considerations

At 16,800 lumens from 120 watts, this fixture operates at 140 lumens per watt. The 5000K color temperature produces a cool white output suited to task-intensive industrial environments where visual clarity supports safety and accuracy. CRI is rated at 70 or higher.

The 120-degree beam angle from the polycarbonate lens spreads light broadly beneath the fixture, reducing the number of units needed to cover open floor areas. This distribution pattern works well in spaces with standard ceiling heights where wide, even coverage is more important than narrow spot intensity.

Operating temperature range spans -22°F to 122°F, covering refrigerated storage through high-ambient processing areas. Power factor above 0.95 and THD under 10 percent indicate clean electrical draw with minimal harmonic distortion, which matters in facilities with sensitive equipment or strict power quality requirements.

Installation and Long-Term Use

The fixture supports three mounting methods: chain or cable suspension, recessed ceiling installation, and surface mounting. At 88 pounds, this unit requires appropriate structural support and typically two people for safe handling during installation. Mounting hardware selection should account for the weight and any vibration present in the space.

The 100-277V input range covers standard commercial and industrial voltage systems without requiring external transformers. Dimming is available via 1-10V protocol for integration with building automation or manual dimming controls where variable output is needed.

Rated lifespan is 50,000 hours at L70, meaning the fixture will maintain at least 70 percent of initial light output at that point. This translates to extended service intervals in continuous-operation facilities. The polycarbonate lens resists breakage better than glass alternatives in high-traffic or high-risk areas.

How This Fixture Is Commonly Used

Facilities replacing 400 watt metal halide systems in hazardous locations use this fixture to reduce energy consumption while maintaining or improving light levels. The transition eliminates restrike delay issues associated with HID sources, providing immediate illumination after power cycling.

The 1-10V dimming capability allows facility operators to reduce output during low-activity periods or adjust light levels based on task requirements. This control integrates with existing building management systems that support the 1-10V protocol.

In washdown environments, the IP66 construction allows direct cleaning without covering or protecting the fixture. Maintenance personnel can include these units in standard sanitation routines without concern for water ingress.

Safety, Certifications, and Warranty

This fixture is UL 844 listed for hazardous locations covering Class 1 Division 2 Groups A, B, C, D, Class 2 Division 1 Groups F, G, and Class 3 environments. The fixture is NSF rated and rebate eligible.

IP66 rating confirms protection against dust ingress and high-pressure water jets. IK09 rating confirms resistance to moderate mechanical impact. These ratings apply across the stated operating temperature range of -22°F to 122°F.

LED Lighting Supply provides a 5-year warranty on this fixture.
