Product Overview

We supply a 250 Watt Explosion Proof LED Light designed for hazardous location lighting, paint booth lighting, and chemical processing environments. This fixture delivers 35,000 lumens at 5000K and is engineered for use in areas where flammable gases, vapors, or combustible dusts may be present. Typical installations include Class I Division 2 and Class II Division 1 or 2 locations, with mounting heights commonly ranging from 18 to 35 feet depending on the space and required light levels.

The fixture is built with a copper-free aluminum housing, tempered glass lens, and is available with yoke or 3/4 inch NPT pendant mounting. It is suitable for both new construction and retrofit projects where legacy 1000W metal halide fixtures are being replaced in hazardous environments.

Core Performance and Output

This 250W explosion proof LED fixture outputs 35,000 lumens, providing an efficacy of 140 lumens per watt. The standard beam angle is 120°, with optional 40°, 60°, or 90° optics for targeted distribution. Color temperature is 5000K with a CRI above 70. The fixture supports 1-10V dimming for output control and operates on either 100-277V or 277-480V input.

Uniformity and coverage are consistent at typical mounting heights for hazardous location applications. At lower mounting heights, output may be excessive for smaller spaces. At mounting heights above 35 feet, narrower optics are recommended to maintain target light levels and minimize spill.

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 room geometries or task requirements. Yoke and pendant mounting options provide flexibility for ceiling, wall, or structure attachment.

No onboard occupancy or daylight sensors are included. External control systems can be integrated as needed for energy management or scheduling in hazardous environments.

Longevity and Reliability

This fixture is rated for 50,000 hours (L70) and includes a 5-year warranty. The copper-free aluminum housing and tempered glass lens provide long-term resistance to corrosion, impact, and chemical exposure. The fixture is IP66 and IK10 rated for protection against dust, water, and mechanical impact.

10kV surge protection is standard. The fixture is designed for continuous operation in ambient temperatures from -40°F to 122°F. Maintenance intervals are minimized due to the sealed design and robust construction.

Build Quality and Physical Characteristics

The housing is constructed from copper-free aluminum with a gray finish. The lens is tempered glass for chemical and impact resistance. The fixture measures 16.6 x 11.8 x 8.3 inches and weighs 32 lbs. All hardware is designed for use in hazardous and corrosive environments.

Mounting options include yoke or 3/4 inch NPT pendant. The fixture is suitable for wet locations and marine outside type environments. All gaskets and seals are rated for hazardous location use and long-term durability.

Where This Product Fits Best

This explosion proof LED fixture is intended for use in hazardous locations where flammable gases, vapors, or combustible dusts are present. It is commonly installed in environments requiring Class I Division 2, Class II Division 1 or 2, or Class III protection. The fixture is also suitable for marine and offshore environments, as well as areas exposed to chemical or solvent vapors.

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

The fixture is designed for use in locations with high ambient temperatures, corrosive atmospheres, or where washdown and impact resistance are required. It is not intended for general-purpose industrial or warehouse lighting outside of hazardous or classified areas.

Installation and Long-Term Use

Yoke and pendant mounting options allow for attachment to ceilings, beams, or conduit systems. The fixture?s weight and dimensions require secure mounting to structural supports rated for hazardous locations. All wiring and connections must comply with hazardous location codes and standards.

Routine inspection of seals and gaskets is recommended in environments with high chemical exposure or frequent washdown. The fixture?s sealed design minimizes dust and moisture ingress, reducing maintenance requirements. Replacement of legacy HID fixtures with this LED unit typically reduces fixture count and maintenance intervals.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 35 feet, depending on the application and required light levels. Spacing is determined by beam angle selection and target uniformity, with narrower optics used for higher mounting or focused task areas. Fixtures are often installed in grid or linear patterns to ensure consistent coverage in hazardous zones.

Higher output allows for wider spacing and reduced fixture count, but may increase glare in confined spaces. Layouts should be coordinated with facility safety requirements and hazardous area zoning.

Safety, Certifications, and Warranty

This fixture is certified to UL 844 for hazardous locations, including 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. Additional certifications include UL 1598 for wet locations, UL 1598A for marine outside type, ABS, ATEX, and IECEx. The fixture is IP66 and IK10 rated.

Operating temperature range is -40°F to 122°F. Surge protection is rated at 10kV. The product includes a 5-year warranty covering manufacturing defects and performance.
