Product Overview
This is a 250 watt explosion proof LED light designed for hazardous locations. It delivers 35,000 lumens at 5000K color temperature and is suitable for use in environments requiring Class I Division 2 protection.
The fixture is built with a copper free aluminum housing and a tempered glass lens. It is available with either a yoke mount or a 3/4 inch NPT pendant mount.
Voltage compatibility covers both 100V-277V and 277V-480V ranges. The fixture supports 1-10V dimming and offers multiple beam angle options, including 120°, 40°, 60°, and 90°.
It is rated for a 50,000 hour L70 lifespan and operates in temperatures from -40°F to 122°F.
Where This Product Fits Best
This explosion proof LED light is intended for hazardous locations where flammable gases, vapors, or dusts may be present. It is suitable for areas classified as Class I Division 2, Class II Division 1 and 2, and Class III.
Common applications include chemical plants, refineries, paint shops, grain processing, and marine environments. The fixture is also suitable for wet locations and marine outside type installations.
Its output and beam angle options allow for use in both general area lighting and more focused task lighting within hazardous zones.
Performance and Functional Considerations
This fixture replaces 1000 watt metal halide systems with a 250 watt LED solution, providing 140 lumens per watt. The 5000K color temperature delivers daylight white illumination with a CRI above 70.
Beam angle options allow for flexibility in coverage, with standard 120° and optional 40°, 60°, or 90° optics. The tempered glass lens supports durability in demanding environments.
Power factor is greater than 0.95 and total harmonic distortion is less than 10%. Surge protection is rated at 10kV.
The fixture is IP66 rated for protection against dust and strong water jets, and IK10 rated for impact resistance.
Installation and Long-Term Use
The fixture can be mounted using either a yoke or a 3/4 inch NPT pendant, supporting installation flexibility in hazardous locations. The housing is constructed from copper free aluminum for corrosion resistance.
Dimensions are 16.6 x 11.8 x 8.3 inches, and the fixture weighs 32 lbs. The design supports operation in ambient temperatures from -40°F to 122°F.
1-10V dimming is supported for integration with compatible dimming controls. The fixture is designed for long-term use with a 50,000 hour L70 rated lifespan.
How This Fixture Is Commonly Used
Once installed, this explosion proof LED light provides consistent illumination in hazardous areas where reliability and safety are critical. The fixture can be adjusted for coverage using the available beam angle options to suit the specific lighting requirements of the space.
