30 / 53 / 75 Watt Adjustable Round Explosion Proof LED Light | 4500 to 11250 Lumens | Class 1 Div 2 | 5000K | 100-277V

Product Overview

This is a wattage-adjustable round explosion proof LED fixture designed for hazardous location lighting. It covers 30, 53, and 75 watt settings, delivering up to 11,250 lumens at 5000K. The fixture is certified for Class I Division 2, Class II Division 2, and Class III environments, supporting use in areas with flammable gases, vapors, dusts, or fibers. Typical installations include chemical processing, paint booths, and other hazardous or explosive risk environments where legacy metal halide fixtures are being replaced.

The fixture supports both yoke and 3/4 inch NPT pendant mounting, allowing for flexible installation on ceilings, walls, or structural supports. The compact round form factor and 120° beam angle provide broad, even coverage in confined or open hazardous spaces.

Core Performance and Output

This fixture offers selectable output at 30, 53, or 75 watts, producing 4,500 to 11,250 lumens. Efficacy is 150 lumens per watt. The 120° beam angle provides wide area coverage, suitable for general illumination in hazardous zones. The fixture operates on 100-277V and maintains a power factor above 0.95 with THD below 20%.

At maximum output, the fixture is appropriate for mounting heights up to 18?22 feet in typical hazardous location layouts. Excessive output may cause glare or over-lighting at lower mounting heights. Uniformity may decrease if spacing exceeds standard hazardous area layout recommendations.

Adjustability and Control Options

The fixture includes field-selectable wattage adjustment, allowing the installer to set the output to 30W, 53W, or 75W as required by the application. This supports both new installations and retrofit scenarios where existing light levels must be matched or improved.

No onboard dimming or advanced control options are provided. The fixture is designed for on/off operation only. Beam angle is fixed at 120° with a tempered glass lens.

Longevity and Reliability

L70 rated life is 164,000 hours, supporting long-term operation in demanding hazardous environments. The fixture is constructed with a copper-free aluminum housing and tempered glass lens for resistance to corrosion and impact.

10kV surge protection is integrated. The fixture is rated for operation from -40°F to 140°F, supporting use in both cold and high ambient temperature hazardous locations.

Build Quality and Physical Characteristics

The fixture housing is copper-free aluminum with a gray finish. The lens is tempered glass. The fixture is IP66 and NEMA 4X rated for dust and water ingress, and IK08 rated for impact resistance. Weight is 11 lbs, and dimensions are 9.7 x 12 inches.

Mounting options include yoke or 3/4 inch NPT pendant. All hardware is designed for hazardous location compliance and long-term durability in corrosive or wet environments.

Where This Product Fits Best

This fixture is intended for hazardous locations where explosive gases, vapors, dusts, or fibers may be present. It is suitable for both new construction and retrofit of legacy hazardous location fixtures. Typical environments include:

• 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

The fixture is designed for use in classified areas requiring UL 844, Class I/II/III, and NEMA 4X/IP66 protection. It is suitable for both indoor and outdoor hazardous environments, including marine and corrosive locations.

Installation and Long-Term Use

Mounting is supported via yoke or 3/4 inch NPT pendant, allowing installation on ceilings, walls, or structural supports. The compact form factor simplifies placement in confined hazardous areas. All wiring and mounting must comply with hazardous location codes and standards.

Routine maintenance is minimized due to the long LED lifespan and robust construction. The fixture is designed for easy wattage adjustment in the field. No relamping or frequent servicing is required under normal operating conditions.

How This Fixture Is Commonly Used

Typical mounting heights range from 10 to 22 feet, depending on the selected wattage and required light levels. Fixtures are spaced to achieve uniform coverage in hazardous zones, with closer spacing at lower wattages or in areas requiring higher illumination.

In retrofit scenarios, fixture count and placement often match existing layouts. Higher output settings can reduce fixture count but may increase glare if not properly spaced. Layouts should be verified against hazardous area lighting requirements and safety codes.

Safety, Certifications, and Warranty

This fixture is certified to UL 844 Hazardous Locations, UL 1598, and UL 1598A Marine Outside Type. It is rated for Class I Division 2 Groups A, B, C, D; Class II Division 2 Groups F, G; and Class III. NEMA 4X and IP66 ratings apply. IK08 impact rating and 10kV surge protection are included.

Operating temperature is -40°F to 140°F. The fixture carries a 5-year warranty. All certifications and ratings are maintained for the life of the product when installed per manufacturer instructions.
