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 150W round LED explosion proof light delivers 21,000 lumens at 5000K for hazardous location lighting, explosion proof lighting, and paint booth lighting. It is available in 100V-277V or 277V-480V configurations and supports 1-10V dimming.
The fixture is rated to replace a 400W metal halide fixture and uses a standard 120-degree beam angle. Optional 40-degree, 60-degree, and 90-degree beam angles are available for projects requiring a different distribution pattern.
Core Performance and Output
With 140 lumens per watt and a 70+ CRI, this fixture provides high-output illumination for classified industrial areas. A tempered glass lens protects the optical system.
The driver operates at 50-60Hz with a power factor greater than 0.95 and total harmonic distortion below 10%.
Adjustability and Control Options
This explosion proof fixture supports 1-10V dimming. Select the required input voltage configuration and beam angle when planning the installation.
Longevity and Reliability
The LED system is rated for 50,000 hours L70 life. The fixture operates in ambient temperatures from -40 degrees F to 140 degrees F and includes 10kV surge protection.
Build Quality and Physical Characteristics
The gray copper-free aluminum housing is rated IP66 and IK10. The round fixture measures 14.56 x 11.4 inches and weighs 18.1 lbs.
Mounting options include a yoke mount or 3/4 in NPT pendant mount.
