250 Watt Explosion Proof Round LED Light | 35000 Lumens | Class 1 Div 2 | 5000K | 100V-277V or 277-480V

Product Overview

This 250 Watt Explosion Proof Round LED Light is designed for hazardous location lighting, explosion proof lighting, and paint booth lighting. It delivers 35,000 lumens at 5000K and is suitable for use in environments where flammable gases, vapors, or dusts may be present. The fixture is built for mounting heights typically found in large industrial spaces and is a direct replacement for 1000W metal halide units.

It is certified for Class I Division 2, Class II Division 1 and 2, and Class III environments. The fixture supports both yoke and 3/4 inch NPT pendant mounting, providing flexibility for installation in chemical processing facilities, oil and gas sites, and marine environments.

Core Performance and Output

This fixture outputs 35,000 lumens at 250 watts, achieving 140 lumens per watt. The standard beam angle is 120°, with optional 40°, 60°, and 90° optics for targeted distribution. Color temperature is 5000K with a CRI above 70. Power factor is greater than 0.95 and THD is below 10%.

It is suitable for mounting heights from 18 to 40 feet, depending on the required light levels and beam angle selection. Excessive output may occur at low mounting heights, and uniformity can be affected at the upper end of the mounting range if narrow optics are not selected.

Adjustability and Control Options

The fixture supports 1-10V dimming for integration with lighting controls or manual adjustment. Multiple beam angle options allow for adaptation to different space geometries and task requirements. Yoke and pendant mounting options provide flexibility for ceiling, wall, or structure attachment.

No integrated motion or occupancy sensors are included. Dimming and control wiring must be planned during installation if advanced control is required.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70) and includes 10kV surge protection. The copper-free aluminum housing and tempered glass lens are designed for long-term durability in harsh and corrosive environments.

Operating temperature range is -40°F to 140°F. The fixture is IP66 rated for dust and water ingress, and is 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. The fixture measures 18.9 x 15.5 inches and weighs 37.5 lbs. All external hardware is designed for corrosion resistance in marine and chemical environments.

The tempered glass lens provides impact resistance and chemical durability. The fixture is ABS certified and UL 1598A listed for marine outside type use.

Where This Product Fits Best

This fixture is intended for hazardous and classified environments where explosive gases, vapors, or dusts are present. It is commonly installed in large industrial spaces, chemical processing areas, and marine or offshore facilities requiring explosion proof lighting.

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

Environmental characteristics include resistance to dust, water, corrosive chemicals, and marine conditions. The fixture is suitable for both indoor and outdoor hazardous locations, including areas with high humidity or salt exposure.

Installation and Long-Term Use

The fixture supports yoke and 3/4 inch NPT pendant mounting. Both mounting options are compatible with standard hazardous location conduit and junction box systems. The fixture weight and size require secure attachment to structural supports rated for hazardous environments.

Routine maintenance is minimized due to the sealed design and long LED lifespan. Access for cleaning or inspection should be planned based on the installation height and surrounding equipment. All wiring and installation must comply with hazardous location electrical codes.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 40 feet, depending on the required light levels and beam angle selection. Fixtures are often spaced to provide uniform coverage in large open areas or targeted illumination in process zones and paint booths.

Layout patterns vary by application, with closer spacing in areas requiring higher uniformity or task lighting. Higher output can reduce fixture count but may increase glare if not paired with appropriate optics or mounting height.

Safety, Certifications, and Warranty

This fixture is certified to UL 844, UL 1598, UL 1598A, and ABS standards. It is rated 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. IP66 ingress protection is provided.

Operating temperature is -40°F to 140°F. The fixture includes a 5-year warranty. All certifications are listed for reference and compliance.
