150 Watt Square Explosion Proof LED Light | 21000 Lumens | Class 1 Div 1 | 5000K | 100V-277V or 277V-480V

Product Overview

The 150 Watt Square Explosion Proof LED Light is designed for hazardous location lighting where flammable gases, vapors, or combustible dusts are present. This fixture delivers 21,000 lumens at 5000K and is suitable for Class I, Division 1 and Division 2, as well as Class II and III environments. Typical installations include chemical processing facilities, paint booths, and oil and gas sites where compliance with UL 844 and related hazardous location standards is required. Yoke mounting and a compact form factor allow for flexible placement in confined or complex layouts.

This model is a direct replacement for 400W metal halide fixtures in hazardous areas, providing improved efficiency and reduced maintenance. The fixture is built for use in both indoor and outdoor hazardous environments, including marine and wet locations, with a tempered glass lens and copper-free aluminum housing for durability.

Core Performance and Output

This fixture outputs 21,000 lumens at 150 watts, achieving 140 lumens per watt. The standard beam angle is 120°, with optional 40°, 60°, or 90° optics for targeted distribution. The fixture supports both 100-277V and 277-480V input, with a power factor above 0.95 and THD below 10%. Color temperature is 5000K with a CRI above 70.

Uniformity and coverage are consistent at typical mounting heights for hazardous location lighting. Excessive output may occur if installed at low mounting heights in small enclosures. At higher mounting heights, narrower optics may be required to maintain target light levels and minimize spill.

Adjustability and Control Options

The fixture includes 1-10V dimming capability for integration with lighting controls or manual adjustment. Yoke mounting allows for precise aiming and orientation, supporting both wall and ceiling installations. Beam angle options provide flexibility for different coverage requirements.

No integrated motion or occupancy sensors are included. Dimming performance is stable across the full voltage range. Control wiring access is provided through the fixture?s sealed housing.

Longevity and Reliability

L70 rated life is 50,000 hours. The fixture is designed for continuous operation in hazardous and corrosive environments, with a -22°F to 122°F operating temperature range. 10kV surge protection is standard.

Maintenance requirements are minimal due to the sealed, non-serviceable LED array and driver. The tempered glass lens and copper-free aluminum housing resist impact and chemical exposure. The fixture is covered by a 5-year warranty.

Build Quality and Physical Characteristics

The housing is constructed from copper-free aluminum with a gray finish. The fixture is IP66 rated for dust and water ingress and IK10 rated for impact resistance. Dimensions are 15.7 x 11.2 x 9.96 inches, and weight is 26.9 lbs.

The tempered glass lens is resistant to solvents and cleaning agents. All hardware is corrosion-resistant. The fixture is suitable for marine and outdoor hazardous locations per UL 1598A and ABS certifications.

Where This Product Fits Best

It is suitable for environments with flammable gases, vapors, or dusts, including both indoor and outdoor settings. The design supports use in marine, chemical, and industrial facilities where compliance with Class I, II, and III standards is necessary.

• 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 suitable for wet, corrosive, and marine environments. It is not intended for general-purpose industrial or commercial spaces outside of hazardous location requirements.

Installation and Long-Term Use

Yoke mounting supports attachment to walls, ceilings, or structural members. The fixture?s weight and size require secure mounting points and consideration of vibration or movement in the installation area. All wiring connections are made within the sealed housing using hazardous location-rated cable entries.

Routine inspection is recommended to verify lens integrity and housing seals, especially in environments with chemical exposure or high humidity. The fixture is designed for minimal maintenance, with no field-serviceable components. Replacement is required at end of life.

How This Fixture Is Commonly Used

Typical mounting heights range from 10 to 25 feet, depending on the area classification and required light levels. Spacing is determined by beam angle selection and target uniformity, with wider optics used for open areas and narrower optics for aisle or task lighting.

Fixtures are often deployed in grid or linear patterns to ensure code-compliant coverage in hazardous zones. Higher output allows for reduced fixture count but may require careful aiming to avoid glare or over-lighting in confined spaces.

Safety, Certifications, and Warranty

This fixture is certified to UL 844 for hazardous locations, including Class I, Division 1 and 2, Groups A-D; Class II, Division 1 and 2, Groups E-G; and Class III. Additional certifications include UL 1598 for wet locations, UL 1598A for marine outside type, and ABS. The fixture is IP66 and IK10 rated.

Standard warranty is 5 years. All components are designed for compliance with hazardous location safety standards. Surge protection is rated at 10kV.
