250 Watt Explosion Proof LED Light | 35000 Lumens | Class 1 Div 2 | Class 2 Div 2 | 5000K | 100V-277V or 277-480V

Product Overview

This 250 watt explosion proof LED fixture delivers 35,000 lumens at 140 lumens per watt with a 5000K color temperature. It replaces 1000 watt metal halide systems in hazardous location applications where ignitable gases, vapors, or combustible dusts may be present.

The fixture is rated for Class I, Division 2, Groups A, B, C, D and Class II, Division 1 and Division 2 applications covering combustible dust environments. Class III rating is also included. Voltage options are 100V-277V or 277V-480V, both operating at 50-60Hz.

Construction uses copper free aluminum housing with a tempered glass lens. The fixture measures 16.6 x 11.8 x 8.3 inches and weighs 32 lbs. Standard beam angle is 120 degrees with optional 40, 60, or 90 degree optics available.

Where This Product Fits Best

This fixture is built for facilities operating under hazardous location classifications where standard LED high bays cannot be installed. Petrochemical plants, refineries, grain handling facilities, paint booths, and fuel storage areas are typical environments. The Class I Division 2 rating covers locations where flammable gases or vapors are not normally present but may occur during abnormal conditions.

Class II Division 1 and Division 2 ratings make this fixture suitable for environments with combustible dust such as grain elevators, flour mills, and coal handling facilities. The marine outside type rating and ABS certification support use in offshore and marine applications where corrosion resistance and environmental durability are required.

Operating temperature range spans -40 degrees F to 122 degrees F, allowing installation in cold storage adjacent areas, outdoor industrial sites, and high ambient temperature process areas. The IP66 rating permits direct exposure to water jets and heavy dust without ingress.

Performance and Functional Considerations

At 35,000 lumens, this fixture provides output equivalent to 1000 watt metal halide while drawing 250 watts. CRI is 70+, which is adequate for general industrial task visibility but may not suit applications requiring precise color differentiation.

The 1-10V dimming capability allows integration with building management systems or manual dimming controls where output adjustment is needed. Power factor exceeds 0.95 and THD is under 10%, supporting clean electrical performance on industrial power systems.

Rated lifespan is 50,000 hours at L70, meaning the fixture will maintain at least 70% of initial lumen output through that period. Surge protection is rated at 10kV, providing resilience against transient voltage events common in industrial electrical environments.

Installation and Long-Term Use

Mounting options include yoke mount for direct surface or structural attachment and 3/4 inch NPT pendant mount for drop installations. The 32 lb weight requires appropriate structural support and may require two-person handling during installation.

IP66 rating allows installation where the fixture will be exposed to high pressure water cleaning, rain, or heavy airborne particulates without compromising the enclosure. IK10 impact rating means the housing withstands significant physical impact from accidental contact with equipment or falling objects.

The copper free aluminum housing resists corrosion in environments where standard aluminum may degrade. The wet location suitability rating permits installation in areas with direct moisture exposure. Gray fixture color is standard.

How This Fixture Is Commonly Used

Facility operators typically install this fixture where existing metal halide explosion proof lighting is being replaced. The yoke mount works well for ceiling or beam attachment in processing areas, while the pendant mount suits applications where the fixture needs to hang below obstructions or at specific heights.

The 120 degree standard beam angle covers broad areas typical of warehouse aisles and open processing floors. Narrower beam options at 40, 60, or 90 degrees concentrate output for higher mounting heights or more focused task lighting in specific work zones.

Dimming via 1-10V allows facilities to reduce output during low-activity periods or balance light levels across zones. The voltage flexibility between 100V-277V and 277V-480V options accommodates different service voltages found across industrial facilities without requiring external transformers.
