Product Overview
This 40 watt explosion proof linear LED light delivers 5600 lumens at 140 lumens per watt in a 5000K color temperature. The fixture replaces 175 to 250 watt metal halide systems while drawing significantly less power. Output is distributed through a polycarbonate lens with a 120-degree beam angle.
The fixture is available in two voltage configurations: 100-277V or 277-480V, both operating at 50-60Hz. It supports 1-10V dimming for output adjustment where reduced light levels are required. CRI is rated at 70 or higher.
Construction uses copper free aluminum housing finished in gray. The fixture measures 47 inches by 4.7 inches by 9.5 inches and weighs 15 pounds. Rated lifespan is 50,000 hours at L70.
Where This Product Fits Best
This fixture is rated for hazardous location use under UL 844. It carries Class I Division 2 certification for Groups A, B, C, and D, and Class II Division 1 certification for Groups E, F, and G. Class II Division 2 Groups F and G and Class III ratings are also included. These classifications cover environments with flammable gases, combustible dust, and ignitable fibers.
The UL 1598A Marine Outside Type rating allows installation in marine and offshore environments exposed to salt air and corrosive conditions. ABS certification is also carried for marine vessel applications.
IP66 rating means the fixture is sealed against dust ingress and protected against high-pressure water jets. IK08 rating allows the fixture to withstand moderate mechanical impact. Operating temperature range spans -22 degrees Fahrenheit to 122 degrees Fahrenheit, supporting both cold storage and high-ambient industrial environments. UL 1598 wet location suitability allows direct exposure to rain and washdown conditions.
Performance and Functional Considerations
At 5600 lumens from 40 watts, this fixture achieves 140 lumens per watt. The 5000K color temperature produces a neutral white light commonly used in industrial work environments. The 120-degree beam angle provides broad coverage suited to linear mounting configurations in aisles, walkways, and process areas.
Power factor exceeds 0.95 and total harmonic distortion is below 10 percent, which supports stable operation on facility electrical systems. The dual voltage availability addresses both standard commercial voltage ranges and higher voltage industrial distribution systems.
The 1-10V dimming capability allows light output to be reduced when full brightness is not required. This requires compatible control infrastructure to be present on site.
Installation and Long-Term Use
Mounting options include bracket, surface, wall, and 3/4 inch NPT pendant configurations. The NPT pendant option allows connection to rigid conduit systems common in hazardous rated installations. At 15 pounds, the fixture requires secure mounting hardware appropriate for the selected method and structure.
The copper free aluminum housing resists corrosion in marine and chemical environments where standard aluminum may degrade. The polycarbonate lens provides impact resistance consistent with industrial use. IP66 sealing allows the fixture to be cleaned with pressurized water without compromising internal components.
Rated lifespan of 50,000 hours at L70 means the fixture will maintain at least 70 percent of initial light output through that service period under normal operating conditions within the specified temperature range.
How This Fixture Is Commonly Used
Facilities replacing metal halide fixtures in hazardous rated spaces use this fixture to reduce energy consumption while maintaining compliant illumination. The linear form factor works well for continuous row mounting along process lines, storage aisles, and equipment corridors where uniform light distribution is needed.
The 1-10V dimming input allows integration with building management systems or manual dimmers where adjustable output is useful. Operators in areas with variable task requirements or daylight contribution can reduce output during periods when full brightness is unnecessary.
In marine and offshore applications, the ABS certification and Marine Outside Type rating allow the fixture to serve in engine rooms, cargo areas, and exterior deck locations where both hazardous classification and marine durability are required.
