40 Watt Round Explosion Proof LED Light | 5600 Lumens | Class 1 Div 2 | Class 2 Div 2 | 5000K | 100V-277V

Product Overview

This 40 watt round explosion proof LED fixture delivers 5600 lumens at 140 lumens per watt in a 5000K color temperature. It replaces 175 to 250 watt metal halide fixtures in classified hazardous locations where ignitable gases, vapors, or combustible dusts may be present.

The fixture carries UL 844 listing for Class I Division 2 Groups A, B, C, D and Class II Division 1 Groups E, F, G as well as Class II Division 2 Groups F, G and Class III locations. It also holds ATEX and IECEx certifications for international hazardous area compliance.

Constructed with copper free aluminum housing, the fixture measures 7.09 x 9.09 inches and weighs 8 pounds. A tempered glass lens protects the LED array. The standard beam angle is 120 degrees with optional 40, 60, or 90 degree optics available.

Where This Product Fits Best

This fixture is built for hazardous classified environments where flammable gases, vapors, or combustible dust particles create explosion risk. Typical applications include petrochemical facilities, grain handling operations, paint spray booths, fuel storage areas, and chemical processing plants.

The UL 1598 wet location rating and UL 1598A marine outside type listing allow installation in exposed outdoor areas, offshore platforms, and marine vessels. The ABS certification supports use in shipboard applications.

With an operating temperature range of -40 degrees F to 140 degrees F, this fixture handles extreme cold storage environments and high ambient heat found in industrial process areas.

Performance and Functional Considerations

At 5600 lumens from 40 watts, this fixture achieves 140 lumens per watt efficiency. The 5000K color temperature provides neutral white light suitable for task visibility in industrial work areas. CRI is rated at 70 or higher.

The fixture accepts 100V-277V or 277V-480V input at 50-60Hz with a power factor greater than .95 and THD under 10 percent. These electrical characteristics support clean power draw on facility distribution systems.

Dimming is available through 1-10V control for facilities requiring adjustable output levels. Rated lifespan is 50,000 hours at L70, meaning the fixture maintains at least 70 percent of initial lumen output through that operating period.

Installation and Long-Term Use

Mounting options include yoke mount and 3/4 inch NPT pendant mount. The yoke provides direct surface or structure attachment while the pendant option allows drop mounting from conduit in ceiling applications.

IP66 rating means the fixture is sealed against dust ingress and protected against powerful water jets from any direction. IK10 impact rating allows the fixture to withstand significant mechanical impact without damage to the housing or lens.

Built-in 10kV surge protection guards against voltage transients common in industrial electrical environments. The copper free aluminum housing resists corrosion in chemical exposure and marine atmospheres. Fixture color is gray.

How This Fixture Is Commonly Used

Facility operators replacing aging metal halide high bays in classified areas use this fixture to maintain required light levels while reducing energy draw. The 175 to 250 watt metal halide replacement rating provides a direct reference point for one-to-one changeouts.

The 1-10V dimming input allows integration with facility lighting control systems where adjustable output is needed for different shift operations or daylight harvesting strategies. Beam angle selection at time of order lets you match distribution to mounting height and spacing requirements.

In environments with mixed classification zones, the dual Class I Division 2 and Class II Division 1 ratings allow this single fixture type to serve areas with different hazard classifications within the same facility.
