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 400 watt round LED explosion proof light delivers 56,000 lumens at 5000K for hazardous location lighting, including high-output installations that require Class I, II, or III classifications. It is available in 100V-277V or 277V-480V configurations and uses a tempered glass lens.
Core Performance and Output
The fixture produces 140 lumens per watt with a 120-degree standard beam angle. Optional 40-degree, 60-degree, and 90-degree beam angles provide alternatives where a narrower distribution is needed.
It is rated to replace a 1000 watt metal halide fixture and supports 1-10V dimming. Power factor is greater than 0.95, with THD below 10%.
Longevity and Reliability
The LED system is rated for 50,000 L70 hours. The fixture operates from -40 F to 140 F and includes 10kV surge protection.
Build Quality and Physical Characteristics
The gray copper-free aluminum housing has an IP66 rating and a tempered glass lens. The round fixture measures 18.9 x 15.5 inches and weighs 37.5 pounds.
Where This Product Fits Best
This fixture is suited to hazardous and industrial locations requiring a high-output, classified lighting fixture with wet-location and marine outside type ratings.
