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

Product Overview

We supply a 250 Watt Round 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 Class I Division 1 and Division 2, Class II, and Class III hazardous areas. Typical installations include oil and gas facilities, refineries, and solvent storage areas where explosive gases, vapors, or dusts are present.

The fixture is built for mounting heights common to high bay hazardous environments, replacing 400W metal halide units. It supports both yoke and 3/4 in NPT pendant mounting, providing flexibility for ceiling, wall, or pendant installations in classified spaces.

Core Performance and Output

This fixture outputs 35,000 lumens at 140 lumens per watt, providing high efficiency for large hazardous spaces. The 120° beam angle delivers wide, even coverage suitable for open layouts and process areas. Color temperature is 5000K with a CRI above 70, supporting visual clarity in industrial settings.

Electrical performance includes 1-10V dimming, power factor above 0.95, and THD below 10%. The fixture operates on 100-277V or 277-480V input, supporting both standard and high-voltage systems. Excessive output may require increased mounting height or wider spacing to control glare in smaller rooms.

Adjustability and Control Options

The fixture supports 1-10V dimming for integration with lighting controls or manual dimming systems. This allows for energy management and adaptation to process requirements or occupancy schedules. No onboard motion or daylight sensors are included; external controls must be specified if needed.

Mounting is adjustable via yoke bracket or pendant stem, allowing for precise aiming and orientation in process areas, booths, or hazardous work zones. The wide beam angle is fixed; no field-changeable optics are available.

Longevity and Reliability

L70 rated life is 50,000 hours, supporting long-term operation in continuous-use environments. The fixture is constructed with copper-free aluminum housing and a tempered glass lens for resistance to corrosion and impact.

Surge protection is rated at 10kV. The fixture is designed for ambient temperatures from -22°F to 122°F. No fan or moving parts are present, reducing maintenance requirements in hazardous and dusty locations.

Build Quality and Physical Characteristics

The fixture measures 16 inches in diameter by 13.5 inches high and weighs 39 lbs. Housing is gray, copper-free aluminum with an IK10 impact rating and IP66 ingress protection. The tempered glass lens is sealed for dust and water resistance.

UL 844, UL 1598, UL 1598A, ATEX, IECEx, and ABS certifications are met. The fixture is suitable for wet locations and marine outside type environments. All hardware is designed for use in classified and corrosive atmospheres.

Where This Product Fits Best

This explosion proof LED high bay is intended for hazardous locations where flammable gases, vapors, or dusts are present. It is commonly installed in:

• hazardous location lighting
• explosion proof lighting
• paint booth lighting
• chemical processing facility lighting
• oil and gas facility lighting
• refinery lighting
• marine environment lighting
• solvent storage area lighting

Environmental characteristics include high resistance to water, dust, impact, and corrosive agents. The fixture is suitable for both indoor and outdoor classified areas, including marine and offshore platforms.

Installation and Long-Term Use

Mounting options include yoke bracket for surface or wall installation and 3/4 in NPT pendant for suspended mounting. The fixture?s weight and size require secure attachment to rated structure. All wiring must comply with hazardous location codes and conduit requirements.

Routine maintenance is limited to periodic inspection and cleaning of the lens and housing. No lamp or ballast replacements are required. The fixture is designed for minimal service in classified environments, reducing exposure to hazardous atmospheres during maintenance.

How This Fixture Is Commonly Used

Typical mounting heights range from 18 to 35 feet, depending on the size of the area and required light levels. Spacing is determined by output, beam angle, and classification requirements, with wider spacing possible in open process areas and tighter spacing in booths or storage zones.

Fixtures are often deployed in grid or linear patterns to ensure uniform coverage and compliance with hazardous area lighting standards. Higher output allows for reduced fixture count but may increase glare if installed at low heights or in confined spaces.

Safety, Certifications, and Warranty

This fixture is certified to UL 844, UL 1598, UL 1598A, ATEX, IECEx, and ABS standards. It is rated for Class I Division 1 and 2, Class II Division 1 and 2, and Class III hazardous locations. IP66 and IK10 ratings are met for ingress and impact protection.

Operating temperature range is -22°F to 122°F. The fixture includes a 5-year warranty covering manufacturing defects and performance. All components are specified for use in hazardous, marine, and corrosive environments.
