150 Watt Round Explosion Proof LED Light | 21000 Lumens | Class 1 Div 2 | Class 2 Div 2 | 5000K | 100V-277V or 277V-480V

Product Overview

This 150 watt round explosion proof LED light delivers 21,000 lumens at 140 lumens per watt, operating at 5000K color temperature with a CRI of 70+. The fixture replaces 400 watt metal halide systems and is rated for 50,000 hours at L70.

Two voltage configurations are available: 100V-277V and 277V-480V. The fixture operates at 50-60Hz with a power factor greater than .95 and THD below 10%. Dimming is supported via 1-10V protocol.

The housing is copper free aluminum with a tempered glass lens. The fixture measures 14.56 x 11.4 inches and weighs 18.1 lbs. Finish color is gray.

Where This Product Fits Best

This fixture is classified for hazardous locations under UL 844. It is rated for Class I, Division 2, Groups A, B, C, D. It is also rated for Class II, Division 1, Groups E, F, G and Class II, Division 2, Groups F, G. Class III environments are included in the classification scope.

ATEX marking covers Zone 2 gas environments (II 3 G Ex ec IIC T6...T3 Gc) and Zone 21 dust environments (II 2 D Ex tb IIIC T85C...T103C Db). IECEx marking covers Ex ec IIC T6...T3 Gc for gas and Ex tb IIIC T85C...T100C Db for dust.

The fixture carries UL 1598 Suitable for Wet Locations and UL 1598A Marine Outside Type certifications. ABS certification is also listed. Operating temperature range is -40F to 140F.

Performance and Functional Considerations

At 21,000 lumens from 150 watts, this fixture produces output comparable to a 400 watt metal halide while drawing significantly less power. The 5000K color temperature provides neutral white light commonly used in industrial environments where visual clarity is prioritized.

Standard beam angle is 120 degrees. Optional beam angles of 40, 60, or 90 degrees are available for applications requiring more concentrated light distribution. Beam angle selection affects how light spreads across the work area and should be matched to mounting height and task requirements.

The 1-10V dimming protocol allows output adjustment when connected to compatible controls. Power factor above .95 and THD below 10% indicate clean electrical characteristics that minimize harmonic interference on facility power systems.

Installation and Long-Term Use

Mounting is supported via yoke or 3/4 inch NPT pendant. The yoke mount allows angle adjustment for wall or ceiling installations. The NPT pendant option accommodates rigid conduit drops common in hazardous location wiring practices.

At 18.1 lbs, the fixture requires appropriate structural support and hardware. The copper free aluminum housing resists corrosion in marine and chemical exposure environments. IP66 rating means the fixture is protected against powerful water jets and complete dust ingress. IK10 rating means the fixture withstands high-energy mechanical impacts.

Surge protection is rated at 10kV, which helps the fixture tolerate electrical transients common in industrial power environments. The 50,000 hour L70 lifespan supports extended service intervals before lumen depreciation reaches 30%.

How This Fixture Is Commonly Used

Once installed, facilities use this fixture in areas where flammable gases, vapors, or combustible dusts may be present. Refineries, chemical processing plants, grain handling facilities, and paint booths are typical environments. The hazardous location ratings define where the fixture can legally and safely operate.

The beam angle you select determines how the light spreads at your mounting height. A 120-degree beam covers wide areas from lower heights. Narrower options concentrate output for higher mounting or focused task lighting. This is chosen before installation based on your layout.

With 1-10V dimming, you can reduce output when full brightness is not needed. This requires a compatible dimming controller wired to the fixture. If no dimmer is connected, the fixture operates at full output.
