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

Product Overview

This 300 Watt Round Explosion Proof LED Light is designed for hazardous location lighting in environments where flammable gases, vapors, or dusts are present. The fixture delivers 42,000 lumens at 5000K, providing high-output illumination for large, high-ceiling spaces. Typical installations include oil and gas facilities, chemical processing plants, and marine environments where Class I, II, or III hazardous ratings are required.

The fixture is engineered to replace 1000W metal halide units, supporting mounting heights commonly found in industrial process areas and refineries. It is suitable for both new construction and retrofit projects where compliance with UL 844, ATEX, IECEx, and marine ratings is mandatory.

Core Performance and Output

This fixture provides 42,000 lumens at 300 watts, achieving an efficacy of 140 lumens per watt. The standard 120° beam angle supports wide-area coverage, while optional 40°, 60°, and 90° optics allow for targeted distribution in tall or congested spaces. The 5000K color temperature delivers clear, high-contrast visibility for operational safety and process monitoring.

Electrical performance includes a power factor above 0.95 and total harmonic distortion below 10%. The fixture supports both 100-277V and 277-480V input, accommodating a range of industrial power systems. Excessive output may require increased mounting height or careful aiming to control glare in confined areas.

Adjustability and Control Options

The fixture supports 1-10V dimming for integration with lighting control systems or manual adjustment to match operational requirements. Multiple beam angle options are available to optimize light distribution for specific process areas or equipment layouts.

Mounting options include a yoke bracket for surface or truss installation and a 3/4 inch NPT pendant for suspended mounting. Both methods allow for precise aiming and alignment in complex hazardous environments.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70), supporting long-term operation in demanding industrial settings. The copper-free aluminum housing and tempered glass lens provide resistance to corrosion, impact, and chemical exposure.

Integrated 10kV surge protection guards against electrical disturbances common in heavy industrial facilities. The fixture maintains performance in ambient temperatures from -40°F to 140°F, suitable for both indoor and outdoor hazardous locations.

Build Quality and Physical Characteristics

The housing is constructed from copper-free aluminum with a gray finish, minimizing corrosion in marine and chemical environments. The fixture is IP66 rated for dust and water ingress, and UL 1598A Marine certified for outdoor and coastal use.

Dimensions are 18.9 x 15.5 inches, with a weight of 37.5 lbs. The tempered glass lens and robust gasketing ensure durability in washdown, offshore, and refinery applications. All hardware is designed for secure installation in vibration-prone or exposed locations.

Where This Product Fits Best

This fixture is intended for hazardous locations where explosion proof, chemical resistant, and marine-rated lighting is required. It is commonly installed in large process areas, refineries, and offshore platforms with high ceilings and demanding environmental conditions.

• hazardous location lighting
• explosion proof lighting
• paint booth lighting
• chemical processing facility lighting
• oil and gas facility lighting
• refinery lighting
• marine environment lighting
• offshore rig lighting

The fixture is suitable for wet, corrosive, and marine environments, and supports installation in both indoor and outdoor hazardous areas. It is not intended for use in general-purpose industrial or commercial spaces without hazardous classification.

Installation and Long-Term Use

Mounting options include yoke and 3/4 inch NPT pendant, supporting installation on ceilings, walls, or structural members. The fixture?s weight and size require secure attachment to rated supports, especially in high-vibration or offshore environments.

Routine maintenance is minimized by the sealed, IP66-rated enclosure and long-life LED array. Access for inspection or cleaning is straightforward, but all work must follow hazardous location safety protocols. The fixture is compatible with standard hazardous area wiring methods and conduit systems.

How This Fixture Is Commonly Used

Typical mounting heights range from 20 to 40 feet, depending on the area size and required light levels. Spacing is determined by beam angle selection and the need for uniform coverage in process areas or equipment zones.

Fixtures are often deployed in grid or linear patterns to support safe egress, equipment operation, and inspection tasks. Higher output allows for wider spacing, but may require shielding or aiming adjustments to control glare in confined or reflective environments.

Safety, Certifications, and Warranty

This fixture is certified to UL 844 for hazardous locations, including Class I Division 2, Class II Division 1 and 2, and Class III. Additional certifications include UL 1598 for wet locations, UL 1598A Marine, ABS, ATEX, and IECEx.

The product includes a 5-year warranty. All certifications and ratings are maintained when installed according to manufacturer instructions and hazardous location codes.
