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 150 watt square explosion proof LED light delivers 21,000 lumens in a compact flood-style housing for hazardous location lighting. It operates at 5000K and is available in 100V-277V or 277V-480V configurations.
The fixture is built for classified areas requiring Class I, II, or III coverage. Its 150 watt output replaces a 400 watt metal halide fixture where the existing layout and light levels support the change.
Core Performance and Output
The fixture produces 21,000 lumens at 140 lumens per watt. Standard distribution is 120 degrees, with optional 40, 60, and 90 degree beam angles available for more controlled aiming.
Electrical performance includes 50-60Hz operation, power factor above 0.95, and THD below 10 percent. The 120 degree optic can create excessive spill when installed close to the target area, while narrower optics require more deliberate aiming to maintain uniform coverage.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming controls must match the selected voltage configuration and the installed control system.
The yoke mount allows directional adjustment after installation. Beam angle selection and yoke aiming work together to control light placement on equipment, work surfaces, and enclosed process areas.
Longevity and Reliability
Rated life is 50,000 L70 hours. The fixture includes 10kV surge protection for electrical disturbance protection.
Operating temperature range is -22 degrees F to 122 degrees F. Long-term performance depends on maintaining the fixture, lens, mounting hardware, wiring connections, and surrounding classified-area conditions.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. A tempered glass lens protects the optical system.
The fixture is rated IP66 and IK10. It measures 15.7 by 11.2 by 9.96 inches and weighs 26.9 pounds, so the yoke mounting surface and supporting structure must carry the fixture weight.
Where This Product Fits Best
This fixture fits classified and hazardous environments requiring a sealed, impact-resistant LED light with directional yoke mounting. The output level supports locations where a 400 watt metal halide replacement is appropriate.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
- solvent storage area lighting
IP66 protection, IK10 impact resistance, wet-location suitability, and the listed hazardous-location classifications support use where moisture, dust, impact exposure, or classified material conditions are present.
Installation and Long-Term Use
The yoke mount requires a stable mounting surface and sufficient clearance for aiming and servicing. Confirm the selected voltage, branch wiring, control wiring, fixture weight, and mounting hardware before installation.
The tempered glass lens should remain clean and free of damage to maintain light distribution. Inspect mounting points, conduit entries, electrical connections, and the fixture exterior during routine maintenance.
How This Fixture Is Commonly Used
In hazardous location lighting and paint booth lighting, the fixture is typically aimed from its yoke mount toward the required task or process area. Mounting height is determined by the selected optic, target light levels, and available mounting structure.
Layouts for chemical processing facility lighting, refinery lighting, and oil and gas facility lighting commonly use fixture aiming to direct output around equipment and process areas. Higher output can reduce fixture count, but beam angle and aiming still control uniformity and glare.
