150 Watt Round Explosion Proof LED Light | 21000 Lumens | Class 1 Div 2 | 5000K | 100-277V | Optional 10 Year Warranty

Product Overview

This 150 watt round explosion proof LED fixture delivers 21,000 lumens at 5000K, producing 140 lumens per watt. It replaces 400 watt metal halide fixtures in hazardous location applications where ignitable gases, vapors, dusts, or fibers may be present.

The fixture carries UL844 listing for Class 1 Division 2 (Groups A, B, C, D), Class 2 Division 1 (Groups E, F, G), Class 2 Division 2 (Groups F, G), Class 3, Class 1 Zone 2 (Group IIC), Zone 20, Zone 21, and Zone 22. It also holds CSA, ATEX, and IECEX certifications.

Construction consists of powder coated aluminum housing with a tempered glass lens. The fixture measures 9.68 inches in height by 14.96 inches in diameter and weighs 20 pounds. Standard fixture color is gray.

Where This Product Fits Best

This fixture is classified for areas where flammable gases, vapors, and combustible dusts may exist under abnormal conditions or are handled in enclosed systems. Class 1 Division 2 covers locations with ignitable concentrations of gases or vapors that are not normally present during standard operations. Class 2 Division 1 and Division 2 ratings address environments with combustible dust.

The IP66 rating means this fixture can handle direct water jets from any direction and complete protection against dust ingress. It is UL listed for wet locations. The IK08 rating allows the fixture to withstand moderate mechanical impact without damage to the housing or lens.

Voltage input spans 100V to 277V at 50-60Hz, covering standard commercial and industrial electrical systems. The 10kV surge protection handles transient voltage events common in industrial electrical environments.

Performance and Functional Considerations

At 21,000 lumens from 150 watts, this fixture provides the light output needed to replace a 400 watt metal halide while reducing energy consumption. The 5000K color temperature produces a daylight-white appearance suited to industrial task visibility. CRI is rated at 70 or higher.

The 120-degree beam angle provides broad light distribution from the tempered glass lens. Rated lifespan reaches 150,000 hours at L70, meaning the fixture will maintain at least 70 percent of initial light output through that service period.

The driver supports 1-10V dimming for integration with building automation or manual dimming systems where output reduction is needed. Power factor exceeds 0.90 and total harmonic distortion stays below 10 percent.

Installation and Long-Term Use

Mounting options include pendant, surface, wall, and trunnion configurations. The fixture ships without a cord, so field wiring is required during installation. At 20 pounds, the fixture weight should be factored into mounting hardware selection and structural support.

The powder coated aluminum housing and tempered glass lens are built to hold up in harsh industrial environments. IP66 and IK08 ratings support long-term durability in facilities with washdown procedures, high humidity, airborne particulates, or physical contact risk from equipment or material handling.

How This Fixture Is Commonly Used

Facilities operating under hazardous location classifications use this fixture where existing metal halide systems are being replaced with LED. The 100-277V input allows the fixture to connect to whatever voltage is available at the mounting location without requiring a transformer or separate driver.

Once installed, the 1-10V dimming capability lets operators reduce light output when full brightness is not needed, such as during shift changes, low-activity periods, or daylight harvesting scenarios where controls are already in place. The fixture does not require regular adjustment after commissioning.

The 150,000-hour rated lifespan reduces the frequency of lamp replacement compared to metal halide, which matters in hazardous locations where maintenance access may require permits, hot work procedures, or equipment shutdowns.

Safety, Certifications, and Warranty

This fixture is UL844 listed for the hazardous location classifications noted above. It carries UL 1598 and UL 1598A listing for wet locations. Additional certifications include CSA, ATEX, and IECEX.

We provide a 5-year warranty as standard. An optional 10-year warranty is available at the time of purchase.
