400 Watt Round Explosion Proof LED Light | 56000 Lumens | Class 1 Div 2 | 5000K | 100V-277V or 277V-480V

Product Overview

We supply the 400 Watt Round Explosion Proof LED Light for hazardous location lighting where explosive gases, vapors, or dusts are present. This fixture is designed for use in environments requiring Class I Division 2, Class II Division 1 and 2, and Class III protection. Typical installations include chemical processing facilities, paint booths, and oil and gas sites where safety and compliance are critical. The fixture is a direct replacement for 1000W metal halide units and is suitable for mounting heights commonly found in large industrial spaces.

The fixture operates at 100V-277V or 277V-480V and delivers 56,000 lumens at 5000K. It is built with a copper-free aluminum housing, tempered glass lens, and is rated for wet locations and marine environments. Mounting options include yoke or 3/4 inch NPT pendant, supporting flexible installation in hazardous and corrosive settings.

Core Performance and Output

This explosion proof LED fixture outputs 56,000 lumens at 400 watts, providing 140 lumens per watt efficiency. It is designed for high bay mounting heights, typically 25 to 40 feet, and delivers uniform illumination in large hazardous areas. The standard 120° beam angle supports wide coverage, with optional 40°, 60°, or 90° optics for targeted distribution where spill light control is required.

Electrical performance includes a power factor above 0.95 and total harmonic distortion below 10%. The fixture supports 1-10V dimming for output adjustment. Excessive output may occur at mounting heights below 20 feet, and uniformity may decrease at heights above 40 feet without proper layout planning.

Adjustability and Control Options

The fixture supports 1-10V dimming for integration with compatible lighting controls. This allows for output reduction during periods of low occupancy or when full illumination is not required. Beam angle options (40°, 60°, 90°, 120°) are available to match the optical distribution to the application, supporting both wide-area and focused lighting needs.

Mounting adjustability is provided by the yoke bracket, which allows for precise aiming, or by pendant mounting for fixed vertical installations. No onboard occupancy or daylight sensors are included; external controls must be specified if required.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70) and includes a 5-year warranty. The copper-free aluminum housing and tempered glass lens provide long-term resistance to corrosion, impact, and chemical exposure. The IP66 rating ensures protection against dust and high-pressure water jets, supporting reliable operation in washdown and marine environments.

Integrated 10kV surge protection guards against voltage spikes common in industrial power systems. The fixture is designed for continuous operation in ambient temperatures from -40°F to 140°F, with no reduction in rated life within this range.

Build Quality and Physical Characteristics

The fixture measures 18.9 by 15.5 inches and weighs 37.5 lbs. The housing is constructed from copper-free aluminum with a gray finish, and the lens is tempered glass for impact and chemical resistance. All hardware is corrosion-resistant, supporting use in marine and chemical environments.

Mounting options include a heavy-duty yoke bracket for surface or truss installation, or a 3/4 inch NPT pendant for suspended mounting. The fixture is sealed to IP66 and certified for marine outside type locations (UL 1598A). All wiring and connections are designed for hazardous location compliance.

Where This Product Fits Best

This fixture is intended for hazardous and explosion risk environments where compliance with Class I, II, and III standards is required. It is suitable for large industrial spaces with high ceilings, including areas exposed to flammable gases, vapors, dusts, or fibers. The fixture is also appropriate for marine and offshore installations where corrosion and moisture are present.

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

The fixture is designed for environments requiring UL 844, ATEX, IECEx, and IP66 certifications. It is suitable for both indoor and outdoor hazardous locations, including areas with high humidity, corrosive atmospheres, or exposure to salt spray.

Installation and Long-Term Use

Installation options include yoke mounting to flat surfaces or trusses, and pendant mounting using a 3/4 inch NPT conduit. The fixture?s weight and size require secure mounting points and proper support, especially in high-vibration or marine environments. All wiring must comply with hazardous location requirements and local codes.

Routine maintenance is minimized due to the sealed design and long LED life. The tempered glass lens can be cleaned with standard non-abrasive methods. Periodic inspection of mounting hardware and electrical connections is recommended in corrosive or high-vibration settings.

How This Fixture Is Commonly Used

This fixture is typically installed at heights between 25 and 40 feet in hazardous classified areas. Spacing and layout depend on the selected beam angle and required light levels, with higher output allowing for wider spacing but potentially increasing glare if not properly aimed. In paint booths and chemical processing areas, narrower optics are often used to control spill light and improve uniformity.

Tradeoff: Using higher output fixtures can reduce the total fixture count, but may require careful aiming and shielding to manage glare and avoid over-lighting sensitive areas.

Safety, Certifications, and Warranty

This fixture is certified to UL 844 for hazardous locations, including Class I Division 2 Groups A, B, C, D; Class II Division 1 Groups E, F, G; Class II Division 2 Groups F, G; and Class III. It is also certified to UL 1598 for wet locations, UL 1598A for marine outside type, and ABS. ATEX and IECEx markings are present for international compliance. The fixture is IP66 rated and includes 10kV surge protection.

A 5-year warranty covers manufacturing defects and LED performance. All certifications are listed on the product label and documentation for compliance verification.
