40 / 60 / 80 Watt Adjustable Square Explosion Proof LED Light | 6400 to 12800 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. It supports 40, 60, or 80 watt operation, delivering up to 12,800 lumens. The fixture is certified for Class I, Division 2 environments and is suitable for both hazardous and marine locations. Typical installations include chemical processing areas, paint booths, and oil and gas facilities where explosive gases or vapors may be present.

Mounting options include yoke or 3/4 inch NPT pendant, supporting flexible installation on ceilings, walls, or structures. The fixture is commonly used as a direct replacement for 175W metal halide units in hazardous or corrosive environments, with mounting heights ranging from 10 to 25 feet depending on output setting and required light levels.

Core Performance and Output

This fixture offers selectable wattages of 40, 60, or 80 watts, producing 6,400 to 12,800 lumens at 160 lumens per watt. The 120° beam angle provides wide coverage suitable for open hazardous areas, process spaces, and marine environments. Color temperature can be set to 4000K, 5000K, or 6500K to match site requirements.

Electrical performance includes 100-277V input, 1-10V dimming, and a power factor above 0.95. Output is consistent across the full voltage range. At lower mounting heights, the 80W setting may produce excessive brightness or glare; at higher mounting heights, uniformity may decrease if spacing is too wide.

Adjustability and Control Options

Wattage and color temperature are field-adjustable, allowing tuning for specific site needs or changes in process requirements. The fixture supports 1-10V dimming for integration with lighting controls or energy management systems.

Adjustments are made via onboard switches, accessible during installation. No external control modules are required. Dimming performance is stable across the full output range.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70) and includes 10kV surge protection. Die-cast aluminum housing and tempered glass lens provide resistance to vibration, impact, and corrosive atmospheres. The fixture is IP66 and NEMA4X rated for dust and water ingress.

UL 844, UL 1598A, and ABS certifications support use in hazardous, wet, and marine environments. The fixture maintains performance in environments subject to vibration (3G) and temperature fluctuations typical of industrial and marine sites.

Build Quality and Physical Characteristics

The housing is die-cast aluminum with a gray finish, designed for durability in harsh environments. The fixture measures 9.84 x 6.3 x 8.25 inches and weighs 9.15 lbs. The tempered glass lens is IK08 impact rated.

Mounting options include yoke or 3/4 inch NPT pendant. No cord is supplied; field wiring is required. The fixture is designed for secure mounting in locations subject to vibration or movement.

Where This Product Fits Best

This fixture is designed for hazardous and explosion risk environments where Class I, Division 2 compliance is required. It is also suitable for marine and offshore locations exposed to salt, moisture, and vibration. Typical installations include process areas, chemical storage, and marine platforms.

• hazardous location lighting
• explosion proof lighting
• paint booth lighting
• chemical processing facility lighting
• oil and gas facility lighting
• refinery lighting
• marine environment lighting
• offshore rig lighting

The fixture is built for environments with explosive gases or vapors, high humidity, corrosive atmospheres, and areas requiring robust ingress protection. It is not intended for general-purpose industrial or commercial spaces outside hazardous or marine categories.

Installation and Long-Term Use

Mounting is supported via yoke or 3/4 inch NPT pendant, allowing ceiling, wall, or structure attachment. The fixture is compact and lightweight for its class, simplifying handling and installation in confined or elevated spaces. Field wiring is required; no cord is provided.

Routine maintenance is minimal due to the sealed housing and long LED life. The fixture is designed for environments where access may be limited and reliability is critical. Periodic inspection of seals and mounting hardware is recommended in high-vibration or marine settings.

How This Fixture Is Commonly Used

Typical mounting heights range from 10 to 25 feet, depending on output setting and required light levels. Fixtures are spaced to achieve uniform coverage in process areas, storage zones, or marine platforms. Layouts often follow grid or perimeter patterns to address hazardous zones and minimize shadowing.

Higher output settings reduce fixture count but may increase glare in confined spaces. Spacing and aiming should be adjusted based on site geometry and hazard classification boundaries.

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 ratings. Vibration resistance is rated to 3G.

Surge protection is 10kV. The fixture includes a 5-year warranty covering manufacturing defects and LED performance. All certifications are current and support use in hazardous, marine, and corrosive environments.
