300 Watt Square Explosion Proof LED Light | 42000 Lumens | Class 1 Div 2 | Class 2 Div 2 | 5000K | 100V-277V or 277V-480V

Product Overview

This 300 watt square explosion proof LED fixture delivers 42,000 lumens at 140 lumens per watt in a 5000K color temperature. It replaces 1000 watt metal halide systems in hazardous classified locations where ignitable gases, vapors, or combustible dusts are present.

The fixture is UL 844 listed for Class I Division 2 Groups A, B, C, D, Class II Division 1 Groups E, F, G, Class II Division 2 Groups F, G, and Class III environments. It carries ATEX and IECEx markings for international hazardous location compliance. Two voltage ranges are available: 100V-277V and 277V-480V.

Construction uses copper free aluminum housing with a tempered glass lens. The fixture measures 16.6 inches by 11.8 inches by 8.3 inches and weighs 32 pounds. A standard 120 degree beam angle ships with the unit, with optional 40, 60, or 90 degree optics available.

Where This Product Fits Best

This fixture is built for locations classified under NEC hazardous area requirements where flammable gases, vapors, or combustible dusts may be present. The Class I Division 2 rating covers areas where ignitable concentrations of gases or vapors are not normally present under standard operating conditions. Class II Division 1 and Division 2 ratings cover locations with combustible dust.

The UL 1598A Marine Outside Type listing makes this fixture appropriate for marine vessel decks and offshore platform areas exposed to salt spray and weather. The wet location rating under UL 1598 supports use in outdoor industrial settings and wash-down areas.

Operating temperature range spans -40 degrees F to 122 degrees F, supporting installation in cold storage facilities, outdoor process areas, and high ambient temperature zones within the rated limit.

Performance and Functional Considerations

At 42,000 lumens from 300 watts, this fixture provides the output needed to replace 1000 watt metal halide in high ceiling applications. The 5000K color temperature produces a bright white light suited to industrial task visibility. CRI is rated at 70 or higher.

The standard 120 degree beam angle provides broad coverage for general area lighting. The 40, 60, and 90 degree optional optics allow narrower distribution for aisle lighting, spot applications, or higher mounting heights where tighter beam control is needed.

Dimming is available via 1-10V protocol. Power factor exceeds 0.95 and total harmonic distortion is under 10 percent. The fixture operates on 50-60Hz input frequency. Rated lifespan is 50,000 hours at L70.

Installation and Long-Term Use

Mounting options include yoke mount and 3/4 inch NPT pendant. The yoke allows wall or ceiling attachment with adjustable aim. The pendant option supports conduit-fed installations typical in hazardous classified areas where rigid conduit runs are required.

The fixture weighs 32 pounds, which requires appropriate structural support and may need two-person handling during installation. The copper free aluminum housing resists corrosion in marine and chemical exposure environments.

IP66 rating means the fixture is sealed against dust ingress and protected against high-pressure water jets from any direction. IK10 rating means the housing withstands significant mechanical impact. Built-in 10kV surge protection guards against electrical transients common in industrial power systems.

How This Fixture Is Commonly Used

Facilities typically select this fixture for classified areas in refineries, chemical processing plants, grain handling facilities, paint spray booths, and offshore platforms. The dual voltage range options allow it to work with both standard commercial power systems and higher voltage industrial distribution.

When the standard 120 degree optic provides too much spread for a specific mounting height or aisle configuration, the optional narrower beam angles let you concentrate output where it is needed. The 1-10V dimming input ties into building automation or manual dimmer controls when output reduction is needed during certain operations or shifts.

The marine outside type listing is relied upon for offshore drilling platforms, shipyards, and coastal industrial facilities where salt air and direct weather exposure are constant. The wet location rating supports installations in outdoor tank farms, loading docks, and areas subject to wash-down cleaning.
