100 Watt Square LED Explosion Proof Light | 14000 Lumens | Class 1 Div 2 | Class 2 Div 2 | 5000K | 100V-277V or 277-480V

Product Overview

This 100 watt square LED explosion proof fixture delivers 14,000 lumens at 5000K, producing 140 lumens per watt. It replaces 250 watt metal halide fixtures in hazardous location applications where ignitable gases, vapors, or combustible dusts may be 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 also carries ATEX and IECEx markings for international hazardous location compliance.

Two voltage configurations are available: 100V-277V and 277V-480V. The fixture operates at 50-60Hz with a power factor greater than 0.95 and THD below 10 percent. Dimming is supported via 1-10V control.

Where This Product Fits Best

This fixture is built for hazardous classified areas where explosive atmospheres from gases, vapors, or combustible dusts require equipment rated to prevent ignition. The Class I Division 2 rating covers locations where flammable gases or vapors are handled but not normally present in ignitable concentrations during standard operations. The Class II Division 1 and Division 2 ratings extend coverage to areas with combustible dust.

The UL 1598A Marine Outside Type listing makes this fixture suitable for marine vessels and offshore platforms. The wet location rating per UL 1598 allows installation in areas exposed to rain, spray, or washdown conditions.

Operating temperature range spans -40 degrees F to 122 degrees F, supporting both cold storage environments and high-ambient industrial spaces. The IP66 rating means the fixture is sealed against dust ingress and protected from powerful water jets. IK10 impact resistance allows the fixture to withstand heavy physical contact without damage to the housing or lens.

Performance and Functional Considerations

At 14,000 lumens from 100 watts, this fixture provides output comparable to a 250 watt metal halide while consuming significantly less power. The 5000K color temperature produces a neutral white light suitable for task visibility in industrial environments. CRI is rated at 70 or higher.

The standard beam angle is 120 degrees, which provides broad coverage from a single fixture. Optional beam angles of 40, 60, or 90 degrees are available for applications requiring more concentrated distribution or higher mounting positions.

A tempered glass lens protects the LED array and maintains optical clarity in demanding conditions. Rated lifespan is 50,000 hours at L70, meaning the fixture will retain at least 70 percent of initial output at that point.

Installation and Long-Term Use

Mounting options include a yoke mount for direct surface or structure attachment, and a 3/4 inch NPT pendant mount for suspended installations using rigid conduit. The fixture measures 12.5 by 9.5 by 6.5 inches and weighs 26 pounds, so structural support and mounting hardware must be selected accordingly.

The housing is constructed from copper-free aluminum, which resists corrosion in chemical and marine environments. The gray finish is standard. Surge protection is rated at 10kV, providing a buffer against electrical transients common in industrial power systems.

The 1-10V dimming input allows integration with compatible control systems for output adjustment. This fixture carries a 5-year warranty.

How This Fixture Is Commonly Used

In most installations, this fixture operates as a direct replacement for aging metal halide high bays in classified areas. Facilities typically install the yoke mount configuration when attaching to structural steel or equipment supports, and switch to pendant mounting when running conduit from ceiling junction boxes in process areas.

Beam angle selection is usually determined by the type of work happening below the fixture. The 120-degree standard distribution works well for general area lighting across open floor space. Narrower optics are chosen when fixtures are mounted higher or when concentrated light is needed on specific equipment or aisles.

The dual voltage availability lets this fixture work on both standard 120V-277V systems and higher voltage 277V-480V industrial distribution, which is common in heavy manufacturing and petrochemical facilities. Dimming capability is used where output reduction supports energy management or where light levels need to change based on shift activity.

Safety, Certifications, and Warranty

This fixture is ETL listed and carries UL 844 certification for hazardous locations. It is UL 1598 listed for wet locations and UL 1598A certified as Marine Outside Type. ABS certification is also included.

ATEX and IECEx markings are present for installations requiring European or international hazardous area compliance. The ATEX marking is II 2 G Ex eb mb IIC T5 to T6 Gb and II 2 D Ex tb IIIC T80 degrees C to T100 degrees C Db. The IECEx marking is Ex eb mb IIC T5 to T6 Gb and Ex tb IIIC T80 degrees C to T100 degrees C Db.

This fixture is rebate eligible. LED Lighting Supply provides a 5-year warranty.
