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 LED high temperature light delivers 19,500 lumens at 5000K for demanding indoor industrial areas with elevated ambient temperatures. It is rated for operation from -40 F to 176 F and is available in 100V-277V or 277V-480V input configurations.
The fixture uses a die-cast aluminum housing, polycarbonate lens, and either eye-hook or trunnion mounting. It is non-dimming and provides a 110 degree standard beam angle.
Core Performance and Output
With 130 lumens per watt, this fixture is identified as a replacement for 400W metal halide lighting. The 5000K color temperature and 70+ CRI configuration are suited to industrial task and area illumination where clear, cool-white light is required.
Optional 30 degree, 90 degree, and 150 degree beam angles provide alternatives to the standard 110 degree distribution for projects requiring a different light pattern.
Longevity and Reliability
The LED system is rated for 100,000 hours L70 life. The fixture includes 12kV surge protection and operates on 50/60 Hz power with a 0.95 power factor and 20% maximum THD.
Build Quality and Physical Characteristics
The gray die-cast aluminum housing is rated IP66 and IK10. The fixture measures 15.8 inches long by 14.4 inches wide by 9.6 inches high and weighs 20.75 lb.
