80 Watt Square Explosion Proof LED Light | 11200 Lumens | Class 1 Div 2 | 5000K | 100V-277V or 277V-480V
This 80W square explosion-proof LED is a practical choice for hazardous locations needing 11,200 lumens, 5000K light, and 140 lm/W efficiency. Its UL hazardous-location classifications, ATEX and IECEx markings support use in qualifying industrial areas, while IP66, IK10 construction, 10kV surge protection, and wet and marine ratings suit demanding environments. Yoke or 3/4 in NPT pendant mounting and selectable optics make it well suited to paint booths, industrial facilities, and marine applications.

Product Lighting Layout Estimator
Use this estimator to calculate approximate fixture count, spacing, and average foot-candles for a simple rectangular space using the selected LED fixture. Enter your room dimensions, mounting height, target foot-candles, light loss factor, and room/layout condition to generate a preliminary lighting layout. When IES photometry is available, workplane height and room reflectance controls are shown.
Project Inputs
Estimated Results
Estimated average foot-candles are preliminary and should be verified with a lighting plan for project-critical applications.
Room / Layout Condition: This field is used only when usable IES photometry is not available. In fallback mode, it acts as a simplified room utilization factor for reflectance, fixture distribution, racking, obstructions, and how much fixture light reaches the work area. Open / light-colored spaces use 0.90, typical warehouses or shops use 0.75, racked or obstructed spaces use 0.60, and dark or complex spaces use 0.45. When IES photometry is active, this field is hidden and the estimator uses the selected workplane height, LLF, and simplified reflectance adjustment instead.
Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data, selected workplane height, light loss factor, and simplified reflectance adjustment to estimate fixture count, average foot-candles, and visual light distribution. The reflectance adjustment is a conservative approximation and is not a full zonal-cavity, radiosity, or professional photometric room calculation. When IES photometry is not available, the estimator uses a simulated beam model based on lumens, mounting height, room/layout condition, light loss factor, and beam angle.
Preliminary Estimate Only: This estimator is intended for simple square or rectangular spaces and should be used as a planning aid, not a final photometric lighting plan. Actual light levels may vary based on fixture optics, selected IES file, mounting conditions, workplane height, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements. Project-critical applications should be verified with a formal lighting plan.
This estimate is a starting point. Warehouses, industrial facilities, hazardous locations, sports areas, schools, healthcare spaces, public areas, and code-sensitive projects may require a reviewed lighting layout before purchase or installation.
Product Overview
This 80 watt square LED explosion proof light delivers 11,200 lumens at 5000K for hazardous location lighting. It is available in 100V-277V or 277V-480V configurations and supports 1-10V dimming.
The fixture can replace a 250 watt metal halide light where its hazardous-location classifications, mounting configuration, and optical distribution meet project requirements.
Core Performance and Output
The fixture produces 140 lumens per watt with a standard 120 degree beam angle. Optional 40 degree, 60 degree, and 90 degree beam angles provide narrower distribution choices where a broad 120 degree pattern is not appropriate.
A tempered glass lens protects the optical assembly. The 5000K color temperature and 70+ CRI configuration provide a cool white output for industrial hazardous-location areas.
Build Quality and Physical Characteristics
The gray copper-free aluminum housing measures 12.5 x 9.5 x 6.5 inches and weighs 26 pounds. It is rated IP66 and IK10, with 10kV surge protection.
The operating temperature range is -22 degrees F to 122 degrees F. Rated life is 50,000 L70 hours.
