300 Watt Square Explosion Proof LED Light | 42000 Lumens | Class 1 Div 2 | 5000K | 100V-277V or 277V-480V

Product Overview

The 300 Watt Square Explosion Proof LED Light is engineered for hazardous location lighting where flammable 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 paint booths, chemical processing areas, and locations where explosion proof certification is mandatory. The fixture delivers 42,000 lumens at 5000K, providing a high-output alternative to 1000W metal halide systems.

With a robust copper-free aluminum housing and tempered glass lens, this fixture is suitable for both indoor and outdoor hazardous environments. The yoke or 3/4 in NPT pendant mounting options support flexible installation on ceilings, walls, or structural supports. The fixture is rated for wet locations and marine outside type applications, supporting deployment in demanding industrial and marine settings.

Core Performance and Output

This fixture produces 42,000 lumens at 300 watts, achieving an efficacy of 140 lumens per watt. The standard 120° beam angle provides broad area coverage, with optional 40°, 60°, or 90° optics available for controlled distribution in targeted zones. The fixture supports both 100-277V and 277-480V input, with a power factor above 0.95 and THD below 10% for stable electrical performance.

Output is suitable for mounting heights from 18 to 35 feet, depending on the required light levels and beam angle selection. Excessive output may occur at low mounting heights, and uniformity can be reduced at extreme heights without proper layout. Dimming is supported 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. Beam angle can be specified at order with 40°, 60°, 90°, or 120° options to match the application?s coverage and uniformity requirements. The yoke mount allows for precise aiming and tilt adjustment during installation.

No onboard occupancy or daylight sensors are included. Control integration is limited to external dimming systems. Pendant mounting provides a fixed orientation, while yoke mounting supports directional aiming for wall or ceiling installations.

Longevity and Reliability

The fixture is rated for 50,000 hours (L70), supporting long-term operation in continuous-use environments. The copper-free aluminum housing and tempered glass lens provide resistance to corrosion, impact, and chemical exposure. The fixture is designed for operation in ambient temperatures from -40°F to 122°F.

Surge protection is rated at 10kV, supporting reliability in facilities with unstable power or frequent switching. The IP66 and IK10 ratings ensure protection against dust, water ingress, and mechanical impact.

Build Quality and Physical Characteristics

The housing is constructed from copper-free aluminum with a gray finish, minimizing corrosion in harsh or marine environments. The tempered glass lens provides impact resistance and chemical durability. The fixture measures 16.6 x 11.8 x 8.3 inches and weighs 32 lbs, supporting secure mounting on structural surfaces.

All hardware and gasketing are designed for hazardous and wet location use. The fixture is suitable for both indoor and outdoor deployment, including marine outside type environments. Mounting options include yoke and 3/4 in NPT pendant for compatibility with a range of installation conditions.

Where This Product Fits Best

This fixture is designed for hazardous locations where explosion proof certification is required. It is commonly installed in environments with flammable gases, vapors, or dusts, and where high-output, reliable lighting is needed for safety and code compliance.

• 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 suitable for both indoor and outdoor hazardous areas, including marine and offshore environments. It is rated for wet locations, high humidity, and corrosive atmospheres. Not intended for general-purpose industrial or warehouse lighting outside of classified hazardous areas.

Installation and Long-Term Use

The fixture supports yoke or 3/4 in NPT pendant mounting for ceiling, wall, or structure attachment. Secure mounting is required due to the fixture?s 32 lb weight and hazardous location requirements. All wiring and conduit entries must comply with hazardous location codes and standards.

Routine maintenance is minimized by the sealed, corrosion-resistant design. The tempered glass lens can be cleaned with standard non-abrasive methods. Long-term use is supported by the fixture?s 50,000-hour rated life and robust construction. Periodic inspection of seals and mounting hardware is recommended in high-vibration or marine environments.

How This Fixture Is Commonly Used

This fixture is typically installed at mounting heights between 18 and 35 feet, depending on the required light levels and beam angle selection. Spacing is determined by the beam angle and target uniformity, with tighter spacing for narrow optics or higher illumination requirements. Layouts often use grid or linear patterns to ensure code-compliant coverage in classified areas.

Higher output reduces the number of fixtures needed for large hazardous zones but may increase glare if installed at low heights or in confined spaces. Beam angle selection is critical for optimizing coverage and minimizing shadowing in complex environments.

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. Additional certifications include UL 1598 for wet locations, UL 1598A for marine outside type, ABS, ATEX, and IECEx. The fixture is IP66 and IK10 rated for ingress and impact protection.

Operating temperature is rated from -40°F to 122°F. Surge protection is 10kV. The fixture includes a 5-year warranty covering manufacturing defects and performance.
