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 offers 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 measures 16 inches in diameter and 13.5 inches in height, with a weight of 39 lbs.

Rated for 50,000 hours (L70), it is suitable for wet locations and marine outside type environments.

Where This Product Fits Best

This fixture is intended for use in hazardous locations where explosive gases, vapors, or 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 suitable for industrial environments such as chemical plants, refineries, grain processing, and other facilities with classified hazardous areas. The IP66 and IK10 ratings allow use in areas exposed to dust, water, and high impact.

The fixture is also UL 1598A Marine Outside Type and ABS listed, supporting use in marine and offshore applications. It can be installed in both indoor and outdoor hazardous locations.

Voltage compatibility with both 100-277V and 277-480V systems allows integration into a wide range of electrical infrastructures.

Performance and Functional Considerations

The fixture delivers 140 lumens per watt, providing high output for spaces requiring strong illumination. The 5000K color temperature supports visibility in industrial settings.

With a CRI of 70+, the fixture provides adequate color rendering for most hazardous location tasks. The 1-10V dimming capability allows for output adjustment when paired with compatible controls.

The tempered glass lens and copper-free aluminum housing provide durability in harsh environments. The fixture is rated for operation from -22°F to 122°F.

Surge protection is rated at 10kV, supporting reliability in areas with electrical disturbances. Power factor is greater than 0.95, and total harmonic distortion is less than 10%.

Installation and Long-Term Use

Mounting options include yoke or 3/4 inch NPT pendant, allowing flexibility for ceiling, wall, or pendant installations. The fixture?s weight and dimensions should be considered when planning mounting points and support structures.

The IP66 rating means the fixture can withstand high-pressure water jets and dust ingress. IK10 impact protection allows use in areas where physical impacts are possible.

The fixture is suitable for wet locations and marine outside type environments, supporting long-term use in exposed or corrosive settings. The copper-free aluminum housing resists corrosion over time.

With a rated lifespan of 50,000 hours (L70), maintenance intervals are extended compared to legacy lighting systems. The fixture is covered by a 5-year warranty from LED Lighting Supply.

How This Fixture Is Commonly Used

Once installed, this fixture provides consistent, high-output lighting in hazardous locations. The 120° beam angle delivers broad coverage, reducing shadowing in open areas.

The 1-10V dimming feature allows you to adjust light levels as needed for specific tasks or operational requirements, provided compatible dimming controls are in place.

The fixture?s robust construction and environmental ratings mean it can be relied on in areas exposed to dust, water, and impacts without frequent intervention. Day-to-day, the fixture operates with minimal attention beyond routine inspection.

In marine or outdoor hazardous areas, the fixture?s corrosion resistance and wet location suitability support reliable operation over time, even in challenging conditions.
