Product Overview
This 80 watt round explosion proof LED fixture delivers 11,200 lumens at 5000K with a 140 lumens per watt efficiency. The fixture includes an integrated junction box and replaces 250 watt metal halide systems in hazardous location applications.
The round aluminum alloy housing measures 9 inches by 11 inches in diameter and weighs 20.9 pounds. A tempered glass lens provides optical protection with a standard 120-degree beam angle. The fixture is available in two voltage configurations: 100-277V or 277-480V, both operating at 50-60Hz.
This fixture carries UL 844 listing for hazardous locations including Class I Division 1 Groups B, C, D and Class I Division 2 Groups A, B, C, D. It is also listed for Class II Division 1 Groups E, F, G, Class II Division 2 Groups F, G, and Class III environments. Additional listings include UL 1598 Suitable for Wet Locations, UL 1598A Marine Outside Type, and ABS certification.
Where This Product Fits Best
This fixture is built for facilities where ignitable gases, vapors, dusts, or fibers may be present during normal operations or abnormal conditions. The Class I Division 1 rating covers areas where hazardous concentrations exist continuously, intermittently, or periodically under normal operating conditions. Class II Division 1 covers locations with combustible dust in suspension or where dust accumulation may interfere with heat dissipation.
The Marine Outside Type listing makes this fixture appropriate for marine vessel applications and offshore installations exposed to saltwater environments. Wet location suitability allows installation in areas with direct water exposure from rain, wash-down procedures, or high-humidity conditions.
Typical environments include oil refineries, chemical processing plants, grain handling facilities, paint spray booths, fuel dispensing areas, mining operations, and marine platforms. The operating temperature range of -22°F to 122°F supports both cold storage and high-ambient industrial settings.
Performance and Functional Considerations
At 11,200 lumens from 80 watts, this fixture produces equivalent light output to a 250 watt metal halide while consuming significantly less power. The 5000K color temperature provides neutral white light suited to industrial task visibility and inspection work. CRI of 70+ supports general industrial applications where basic color distinction is adequate.
The 120-degree beam angle distributes light broadly from a single point, reducing the number of fixtures needed for general area coverage in open spaces. Power factor greater than 0.95 and THD below 10% indicate clean electrical characteristics that minimize interference with facility power systems and sensitive equipment.
Rated lifespan of 150,000 hours at L70 means the fixture is expected to maintain at least 70% of initial lumen output through that operational period. The 10kV surge protection rating provides resilience against electrical transients common in industrial power environments.
Installation and Long-Term Use
Two mounting options are available: yoke mount for ceiling or wall attachment, and 3/4-inch NPT pendant mount for suspended installations with rigid conduit. The integrated junction box simplifies wiring connections within the hazardous location enclosure system.
IP66 rating means the fixture is sealed against dust ingress and protected against high-pressure water jets from any direction. IK08 impact resistance protects the housing and lens against moderate mechanical impact in environments where contact with equipment, materials, or personnel may occur.
The aluminum alloy housing and tempered glass lens are engineered for sustained operation in chemically aggressive and physically demanding industrial environments. At 20.9 pounds, the fixture requires appropriate structural support consideration during installation planning. The gray finish provides a neutral appearance consistent with industrial equipment standards.
How This Fixture Is Commonly Used
Facilities typically deploy this fixture in process areas, tank farms, loading docks, and equipment rooms where hazardous atmospheres require certified lighting. The dual voltage availability allows installation across different facility electrical systems without requiring transformer modifications.
The yoke mount is commonly selected for ceiling attachment in lower-height applications or for angled wall mounting where directional coverage is needed. Pendant mounting with 3/4-inch NPT conduit is standard for higher ceiling installations where the fixture needs to hang below structural obstructions or ductwork.
Once installed, the fixture operates continuously without adjustment. The sealed construction eliminates maintenance access to internal components, which is intentional for hazardous location integrity. Lens cleaning and external inspection represent the primary ongoing maintenance activities.
Safety, Certifications, and Warranty
This fixture is UL 844 listed for hazardous locations. It is UL 1598 listed as Suitable for Wet Locations and UL 1598A listed as Marine Outside Type. ABS certification is included for marine applications.
