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 50 watt LED high temperature light delivers 6,500 lumens at 5000K for industrial areas exposed to elevated ambient temperatures. It is available in 100V-277V or 277V-480V configurations and operates in temperatures from -40F to 176F.
The fixture uses a die-cast aluminum housing, polycarbonate lens, and either eye-hook or trunnion mounting. Its 110 degree standard beam angle provides broad illumination, with 30 degree, 90 degree, and 150 degree beam angle options available.
Core Performance and Output
With 130 lumens per watt, this fixture provides 6,500 lumens while using 50 watts. It is suitable for projects replacing 175 watt metal halide fixtures where the lighting layout and required output support this configuration.
The 5000K color temperature provides a cool white appearance, and the fixture has a CRI of 70 or higher. It operates on 50/60 Hz power with a 0.95 power factor and maximum 20% THD.
Adjustability and Control Options
This high temperature fixture is not dimmable. Select the required voltage configuration, mounting method, and beam angle before installation.
Longevity and Reliability
The LED system is rated for 100,000 L70 hours. The fixture includes 12kV surge protection and is built for operation in ambient temperatures up to 176F.
Build Quality and Physical Characteristics
The gray die-cast aluminum housing is IP66 rated and IK10 rated. The fixture measures 9.3 inches long by 14.4 inches wide by 9.6 inches high and weighs 17.2 pounds.
