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

Product Overview

This 250 Watt round explosion proof LED fixture delivers 35,000 lumens at 5000K. It is designed for hazardous locations requiring Class I Division 1 and Class II Division 1 protection.

The fixture operates on either 100-277V or 277-480V input and provides a 120° beam angle through a tempered glass lens. It is built with a copper-free aluminum housing and finished in gray.

It replaces 400 Watt metal halide systems and supports 1-10V dimming. The fixture is rated for 50,000 hours (L70) and includes 10kV surge protection.

Mounting options include yoke or 3/4 inch NPT pendant. The fixture measures 16 inches in diameter, 13.5 inches in height, and weighs 39 lbs.

Where This Product Fits Best

This fixture is suitable for hazardous environments where flammable gases, vapors, or combustible dusts are present. It meets UL 844 requirements for Class I Division 1 Groups C and D, and Class II Division 1 Groups E, F, and G.

It is also rated for marine outside type (UL 1598A) and wet locations (UL 1598), supporting use in areas exposed to moisture or outdoor conditions.

The IP66 rating allows use in locations subject to high-pressure water or dust ingress. The fixture is also ABS certified for marine and offshore applications.

Operating temperature range is -22°F to 122°F, supporting use in cold storage, process areas, or outdoor hazardous zones.

Performance and Functional Considerations

The fixture provides 140 lumens per watt and a CRI of 70+, supporting general area lighting in hazardous locations. Output is consistent across the voltage range of 100-277V or 277-480V at 50-60Hz.

1-10V dimming is supported for applications requiring adjustable light levels. Power factor is greater than 0.95 and total harmonic distortion is less than 10%.

The tempered glass lens and IK10 rating allow the fixture to withstand high impact and physical abuse. The 10kV surge protection supports reliability in electrically noisy environments.

Beam angle is 120°, providing wide area coverage. The fixture is designed for long-term use with a 50,000 hour (L70) rated lifespan.

Installation and Long-Term Use

Mounting options include yoke or 3/4 inch NPT pendant, supporting ceiling, wall, or pendant installations. The fixture weighs 39 lbs and measures 16 inches in diameter by 13.5 inches in height.

The copper-free aluminum housing resists corrosion in harsh or marine environments. The IP66 rating allows for hose-down and dust-prone areas.

Maintenance requirements are reduced due to the long LED lifespan and robust construction. The fixture is suitable for both new installations and retrofit projects replacing 400W metal halide units.

All wiring and installation should follow hazardous location requirements as defined by local and national codes.

How This Fixture Is Commonly Used

Once installed, this fixture provides consistent, wide-area illumination in hazardous locations. The 1-10V dimming allows you to adjust light levels as needed for process changes or shift work.

The fixture?s impact resistance and sealed construction mean it can be relied on in areas with heavy equipment movement, airborne dust, or exposure to water spray. You can clean the fixture with standard hose-down procedures without risk of water ingress.

Day-to-day, the fixture operates with minimal attention. The tempered glass lens and aluminum housing hold up to routine impacts and vibration. The fixture?s output and color temperature remain stable over time, supporting visual clarity in work areas.

Routine inspection is straightforward due to the accessible mounting and robust build. The fixture?s design supports long intervals between maintenance cycles.
