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 250 watt round LED explosion proof light delivers 35,000 lumens at 5000K for hazardous location lighting. It is available in 100-277V or 277-480V configurations and uses a 120 degree beam angle with a tempered glass lens.
The fixture is designed for Class I, II, and III hazardous locations within its listed classifications. It can replace a 400 watt metal halide fixture where its electrical, mounting, and hazardous-location ratings match the project requirements.
Core Performance and Output
At 140 lumens per watt, this fixture combines 35,000 lumens of output with 250 watts of input power. The 5000K color temperature and 70+ CRI provide a cool white light output for industrial hazardous-area lighting.
The fixture operates on 50-60Hz power and has a power factor greater than 0.95 with THD below 10%. It supports 1-10V dimming.
Longevity and Reliability
The LED system is rated for 50,000 L70 hours. The fixture operates from -22 degrees F to 122 degrees F and includes 10kV surge protection.
An IP66 rating supports protection against dust and powerful water jets, while the IK10 rating addresses impact resistance. The copper-free aluminum housing and tempered glass lens provide a durable enclosed fixture construction.
Build Quality and Physical Characteristics
This gray round fixture measures 16 inches in diameter by 13.5 inches high and weighs 39 pounds. Mounting options are yoke mounting or 3/4 inch NPT pendant mounting.
Where This Product Fits Best
This fixture is suited to hazardous-area lighting projects requiring a high-output, enclosed LED luminaire with Class I, II, and III hazardous-location classifications.
- hazardous location lighting
- explosion proof lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
- wastewater treatment lighting
Safety, Certifications, and Warranty
