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

Product Overview

We supply the 400 Watt Square Explosion Proof LED Light for hazardous location lighting where flammable gases, vapors, or dusts are present. This fixture is designed for use in Class I Division 2, Class II Division 1 and 2, and Class III environments, with full compliance to UL 844, ATEX, and IECEx standards. Typical installations include paint booths, chemical processing areas, and oil and gas facilities where safety and code 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.

Available with yoke or 3/4 inch NPT pendant mounting, this fixture is built for demanding environments requiring robust construction and reliable performance. The tempered glass lens and copper-free aluminum housing provide durability in both indoor and outdoor hazardous locations.

Core Performance and Output

This fixture delivers 56,000 lumens at 400 watts, achieving 140 lumens per watt. The 5000K color temperature supports high-visibility tasks in hazardous environments. Standard beam angle is 120°, with optional 40°, 60°, or 90° optics for targeted distribution. Power factor exceeds 0.95, and total harmonic distortion is below 10% for stable electrical performance.

Output is suitable for mounting heights from 20 to 40 feet, depending on the required light levels and beam angle selected. Excessive output may occur at low mounting heights, and uniformity can be reduced at extreme heights without proper layout. Dimming is available via 1-10V controls for further adjustment.

Adjustability and Control Options

The fixture supports 1-10V dimming for integration with lighting control systems or manual adjustment. Multiple beam angle options allow for tailored light distribution based on application needs. Yoke and pendant mounting options provide flexibility for ceiling, wall, or structure attachment.

Beam angle selection should be matched to the area size and mounting height to avoid over-lighting or glare. Controls and dimming performance are stable across the full voltage range (100-277V or 277-480V).

Longevity and Reliability

L70 rated life is 50,000 hours, supporting long-term operation in continuous-use environments. The fixture is designed for minimal maintenance, with no lamps or ballasts to replace. Surge protection is rated at 10kV to withstand electrical disturbances common in industrial settings.

Operating temperature range is -40°F to 122°F, allowing use in both cold storage and high-ambient industrial spaces. The fixture maintains performance in environments with dust, moisture, and vibration.

Build Quality and Physical Characteristics

The housing is copper-free aluminum with a gray finish, providing corrosion resistance in chemical and marine environments. The tempered glass lens is impact rated to IK10. The fixture is IP66 rated for dust and water ingress, and UL 1598A Marine Outside Type certified for outdoor and marine use.

Dimensions are 16.6 x 11.8 x 8.3 inches, with a weight of 36 lbs. All hardware and seals are designed for hazardous and wet locations. Mounting options include yoke or 3/4 inch NPT pendant for secure installation on ceilings, walls, or structures.

• paint booth lighting
• chemical processing facility lighting
• oil and gas facility lighting
• refinery lighting
• marine environment lighting
• wastewater treatment lighting

Environmental characteristics include resistance to dust, water, chemicals, and impact. The fixture is suitable for both indoor and outdoor hazardous areas, including marine and offshore locations.

Installation and Long-Term Use

Mounting is available via yoke or 3/4 inch NPT pendant, supporting ceiling, wall, or structure attachment. The fixture?s weight and size require secure mounting points and may need two-person handling for overhead installation. All wiring and connections must comply with hazardous location codes and be performed by qualified personnel.

Routine maintenance is limited to periodic inspection and cleaning of the lens and housing. No lamp or ballast changes are required. The fixture?s robust construction and ingress protection minimize downtime in demanding environments.

How This Fixture Is Commonly Used

Typical mounting heights range from 20 to 40 feet, depending on the application and required light levels. Spacing is determined by beam angle selection and target uniformity, with tighter spacing for narrow optics or higher mounting heights. Fixtures are often laid out in grid or linear patterns to achieve code-required illumination and minimize shadowing.

Higher output reduces the total fixture count but may increase glare if not paired with appropriate optics or controls. Dimming and beam angle selection should be coordinated during planning to balance energy use and visual comfort.

Safety, Certifications, and Warranty

This fixture is certified to UL 844 for hazardous locations, with Class I Division 2, Class II Division 1 and 2, and Class III ratings. Additional certifications include UL 1598, UL 1598A Marine Outside Type, ABS, ATEX, and IECEx. IP66 and IK10 ratings confirm resistance to dust, water, and impact.

Warranty is 5 years. All certifications are listed for reference and compliance documentation.
