    Product Overview

    This 400 Watt Round Explosion Proof LED Light delivers 56,000 lumens at 5000K. It is designed for hazardous locations and classified for use in Class I Division 2, Class II Division 1 and 2, and Class III environments. The fixture is built with a copper-free aluminum housing and a tempered glass lens.

    Voltage compatibility covers both 100V-277V and 277V-480V ranges. The fixture supports 1-10V dimming and offers a standard 120° beam angle, with optional 40°, 60°, or 90° optics. The color rendering index is 70+.

    It is rated for wet locations under UL 1598 and marine outside type under UL 1598A. The fixture is IP66 rated and includes 10kV surge protection. Operating temperature range is -40°F to 140°F.

    Dimensions are 18.9 by 15.5 inches, and the fixture weighs 37.5 lbs. Mounting options include yoke or 3/4 inch NPT pendant.

    Where This Product Fits Best

    This fixture is suitable for hazardous locations where explosive gases, vapors, or dusts may be present. It is classified for use in environments requiring Class I Division 2, Class II Division 1 and 2, and Class III protection.

    It is appropriate for facilities such as chemical plants, refineries, grain processing, and other industrial sites with hazardous atmospheres. The IP66 rating allows use in areas exposed to water, dust, or heavy washdown.

    The marine outside type rating supports installation in outdoor or coastal environments where corrosion resistance is required. The fixture is also suitable for wet locations as defined by UL 1598.

    With a 400 watt input and 56,000 lumen output, this fixture is intended to replace 1000 watt metal halide systems in large, high-ceiling spaces.

    Performance and Functional Considerations

    The fixture delivers 140 lumens per watt and maintains a power factor above 0.95 with total harmonic distortion below 10%. The 1-10V dimming capability allows for integration with compatible dimming controls.

    Beam angle options (120°, 90°, 60°, 40°) allow adjustment of light distribution to match the application. The tempered glass lens provides impact resistance and optical clarity.

    The copper-free aluminum housing resists corrosion in harsh environments. The fixture is designed for a minimum L70 lifespan of 50,000 hours.

    10kV surge protection is built in to handle electrical disturbances common in industrial settings. The fixture operates reliably in ambient temperatures from -40°F to 140°F.

    Installation and Long-Term Use

    Mounting options include yoke or 3/4 inch NPT pendant, supporting both ceiling and pendant installations. The fixture weighs 37.5 lbs and measures 18.9 by 15.5 inches, so appropriate mounting structure and hardware should be used.

    The IP66 rating allows for installation in areas subject to dust, water spray, or washdown. The fixture is suitable for both indoor and outdoor hazardous locations, including marine and wet environments.

    Routine maintenance is minimized by the sealed design and long LED lifespan. The tempered glass lens and corrosion-resistant housing support long-term durability in demanding conditions.

    All wiring and installation should follow hazardous location requirements and local electrical codes. The fixture supports both 100V-277V and 277V-480V input ranges, so voltage compatibility should be confirmed before installation.

    How This Fixture Is Commonly Used

    After installation, this fixture provides consistent, high-output illumination in hazardous areas. The available beam angle options allow you to tailor the light spread to your space, whether you need wide coverage or more focused lighting.

    The 1-10V dimming feature can be used with compatible controls to adjust light levels as needed for different tasks or shifts. The fixture?s sealed construction means you can rely on it in environments with dust, moisture, or corrosive elements.

    Once mounted, the fixture requires minimal attention beyond periodic inspection. The robust housing and lens stand up to impacts and harsh cleaning routines common in industrial settings.

    In day-to-day operation, you can expect stable performance across the full rated temperature range, with no need for frequent lamp changes or lens replacements.
