120 / 150 / 200 Watt Adjustable Square Explosion Proof LED Light | 21000 to 35000 Lumens | Class 1 Div 2 | 4000K / 5000K / 6500K | 100-277V

Product Overview

This is an adjustable-output, square-form LED explosion proof fixture designed for hazardous location lighting, paint booth lighting, and chemical processing facility lighting. The fixture supports selectable wattages of 120, 150, or 200 watts, delivering up to 35,000 lumens. It is suitable for Class I, Division 2, Groups A, B, C, D environments and is built for use in areas where flammable gases or vapors may be present under abnormal conditions.

Typical installations include mounting heights from 15 to 30 feet in hazardous industrial spaces, paint booths, and chemical processing areas. The fixture is engineered for both new construction and retrofit projects where compliance with UL 844 and related hazardous location standards is required.

Core Performance and Output

This fixture provides three selectable output levels: 21,000, 26,250, or 35,000 lumens, with an efficacy of 175 lumens per watt. The 110° beam angle delivers wide, uniform coverage suitable for open hazardous areas and booth environments. Color temperature can be set to 4000K, 5000K, or 6500K to match process or inspection requirements.

Electrical performance includes 100-277V input, power factor above 0.95, and THD below 10%. 1-10V dimming is standard. Output at the highest setting may be excessive for confined or low-ceiling spaces; for mounting heights below 15 feet, glare and over-lighting should be considered. Uniformity may decrease at mounting heights above 30 feet without supplemental fixtures.

Adjustability and Control Options

Wattage and color temperature are both field-adjustable, allowing adaptation to changing process needs or site requirements. The fixture supports 1-10V dimming for integration with hazardous location-rated lighting controls. No onboard occupancy or daylight sensors are included; external controls must be rated for hazardous locations.

Adjustments are made via internal switches, accessible during installation. Once set, changes require de-energizing and opening the fixture, following hazardous location safety protocols.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70) at full output. Die-cast aluminum housing, tempered glass lens, and IP66 ingress protection support long-term operation in wet, dusty, or corrosive environments. IK08 impact rating and 10kV surge protection are standard.

Operating temperature range is -40°F to 122°F. Vibration resistance is rated to 3G. The fixture is designed for continuous duty in demanding industrial and marine environments where maintenance access may be limited.

Build Quality and Physical Characteristics

The housing is die-cast aluminum with a gray finish, designed for durability and corrosion resistance. The fixture measures 14.96 x 9.06 x 11.82 inches and weighs 33.29 lbs. The tempered glass lens is sealed to NEMA4X and IP66 standards for water and dust ingress.

Mounting options include yoke or 3/4 inch NPT pendant. No cord is supplied; field wiring is required. All hardware is designed for hazardous location compliance and marine outside type environments (UL 1598A, ABS).

Where This Product Fits Best

This fixture is intended for hazardous industrial and process environments where explosive gases or vapors may be 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
• wastewater treatment lighting

Environmental characteristics include resistance to water, dust, vibration, and corrosive atmospheres. The fixture is suitable for both indoor and outdoor hazardous locations, including marine and offshore applications.

Installation and Long-Term Use

Mounting is via yoke or 3/4 inch NPT pendant, supporting ceiling, wall, or pendant installations. The fixture?s weight and size require secure mounting to rated structure. All wiring and installation must comply with hazardous location codes and site safety protocols.

Routine maintenance is minimized by the sealed design and long LED life. Field adjustments to wattage or color temperature require de-energizing and opening the fixture. Periodic inspection of seals and mounting hardware is recommended in corrosive or high-vibration environments.

How This Fixture Is Commonly Used

Typical mounting heights range from 15 to 30 feet, depending on output setting and area size. Spacing is determined by required light levels and hazard classification, with wider spacing possible at higher wattages. Fixtures are often deployed in grid or linear layouts to ensure uniform coverage in process areas, booths, or open hazardous spaces.

Higher output settings reduce fixture count but may increase glare in confined areas. For paint booths and inspection zones, color temperature selection is often set to 5000K or 6500K for visual clarity.

Safety, Certifications, and Warranty

This fixture is certified to UL 844 (Hazardous Locations), Class I Division 2 Groups A, B, C, D, UL 1598 (Wet Locations), UL 1598A (Marine Outside Type), and ABS. It meets NEMA4X, IP66, and IK08 standards. Vibration resistance is rated to 3G. Surge protection is 10kV. Warranty is 5 years from date of installation.

All installation and maintenance must follow hazardous location safety procedures. Only qualified personnel should service or adjust the fixture.

Frequently Asked Questions
