100 Watt Square Explosion Proof LED Light | 14000 Lumens | Class 1 Div 1 | 5000K | 100V-277V or 277V-480V
This 100-watt LED hazardous location fixture is a strong choice for demanding industrial environments due to its UL 844 and UL 1598 compliance, IP66 and IK10 ratings, and robust copper-free aluminum construction with a tempered glass lens. Its 14,000-lumen output and selectable beam angles allow tailored lighting for both general and task areas, while 1-10V dimming supports operational flexibility. The fixture is well-suited for chemical plants, refineries, marine facilities, and grain processing sites where hazardous atmospheres, dust, water, or corrosive exposure are present, and where reliable, low-maintenance illumination is critical.

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 100 watt square explosion proof LED light delivers 14,000 lumens at 5000K for hazardous location lighting, explosion proof lighting, paint booth lighting, and chemical processing facility lighting. The fixture uses a copper free aluminum housing, tempered glass lens, and yoke mounting arrangement.
Its output replaces a 200 watt metal halide fixture. The square form factor supports directional aiming where the installation requires light to be aimed across equipment, work surfaces, or defined hazardous areas.
Core Performance and Output
The fixture produces 14,000 lumens at 140 lumens per watt. Standard distribution is 120 degrees, with 40 degree, 60 degree, and 90 degree optical options available for more controlled light direction.
It operates on 100V-277V or 277V-480V input voltage at 50-60Hz. Power factor is greater than 0.95 and total harmonic distortion is less than 10%.
The 120 degree distribution suits broader coverage patterns. Narrower optics require a layout that accounts for aimed coverage and reduced side-to-side spread.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming controls must be matched to the selected voltage configuration and the installed control system.
The yoke mount allows the fixture to be aimed after mounting. Final aiming should account for the selected beam angle, equipment location, and required light distribution.
Longevity and Reliability
Rated life is 50,000 L70 hours. The fixture includes 10kV surge protection for electrical transient resistance.
Operating temperature range is -22F to 122F. Long-term performance depends on maintaining the housing, lens, wiring connections, and mounting hardware.
Build Quality and Physical Characteristics
The housing is copper free aluminum with a gray finish. A tempered glass lens protects the optical assembly.
The fixture is IP66 rated and IK10 rated. Dimensions are 15.7 x 11.2 x 9.96 inches, and fixture weight is 26.9 pounds.
Yoke mounting requires a mounting surface and hardware capable of supporting the fixture weight and maintaining the intended aiming position.
Where This Product Fits Best
This fixture fits hazardous and classified environments where the listed Class I, Class II, and Class III ratings align with site conditions. Its 14,000 lumen output and selectable optics support installations requiring either broad or controlled distribution.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- explosion proof lighting
- oil and gas facility lighting
- refinery lighting
IP66, IK10, wet location suitability, and the listed hazardous location classifications support use where the installation conditions match the fixture ratings.
Installation and Long-Term Use
Install the fixture using the yoke mount and a structure that supports the 26.9 pound fixture weight. Confirm the selected input voltage, branch wiring, dimming arrangement, and optical configuration before energizing the fixture.
Maintain access to the fixture for lens inspection, hardware checks, and electrical service. Yoke aiming should be secured after final field adjustment.
How This Fixture Is Commonly Used
Mounting height is determined by the hazardous location layout, required light levels, selected optic, and the position of equipment or work areas. Broad 120 degree distribution is typically arranged for wider coverage, while 40 degree, 60 degree, and 90 degree optics are aimed for more concentrated coverage.
Fixture spacing and layout patterns vary with mounting height, target illumination, and beam angle. Higher output can reduce fixture count, but uncontrolled aiming or overly broad distribution can place light outside the intended area.
