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 300 watt round explosion proof LED light delivers 42,000 lumens at 5000K for hazardous-location lighting. It is available in 100V-277V or 277V-480V configurations and supports 1-10V dimming.
The fixture is rated for Class I, Division 2 Groups A, B, C, and D; Class II, Division 1 Groups E, F, and G; Class II, Division 2 Groups F and G; and Class III locations. It can replace a 1000 watt metal halide fixture where the lighting design and hazardous-location classification support its use.
Core Performance and Output
The 300 watt LED system produces 42,000 lumens at 140 lumens per watt with a 70+ CRI. A standard 120 degree beam angle provides broad distribution, while 40 degree, 60 degree, and 90 degree optics are available for more focused lighting patterns.
A tempered glass lens protects the optical system. The fixture operates on 50-60Hz power and has a power factor greater than 0.95 with total harmonic distortion below 10%.
Build Quality and Physical Characteristics
The gray copper-free aluminum housing is IP66 rated and includes 10kV surge protection. The fixture measures 18.9 x 15.5 inches and weighs 37.5 pounds.
It is rated for operation from -40 degrees F to 140 degrees F and has a 50,000-hour L70 rated life.
