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 explosion proof LED light produces 35,000 lumens at 5000K for hazardous location lighting, explosion proof lighting, paint booth lighting, and chemical processing facility lighting.
The fixture is rated for Class I, Division 1 and Division 2 locations, Class II Division 1 and Division 2 locations, and Class III locations. It replaces a 400-watt metal halide fixture where the existing hazardous-location classification and mounting arrangement are compatible.
Core Performance and Output
The fixture delivers 35,000 lumens at 140 lumens per watt. The standard 120 degree beam angle provides broad distribution from the round high bay form factor.
It operates on 100-277V or 277-480V, 50-60Hz power. Power factor is greater than 0.95 and THD is less than 10 percent.
The 35,000-lumen output requires layout review at lower mounting heights to avoid excessive light levels. Higher mounting positions may require closer fixture placement to maintain uniformity with the 120 degree distribution.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming controls must match the installed voltage configuration and project control requirements.
The standard optic uses a tempered glass lens with a 120 degree beam angle. No alternate beam angles are listed for this fixture.
Longevity and Reliability
The rated service life is 50,000 L70 hours. The fixture includes 10kV surge protection for electrical transient protection.
Operating temperature range is -22F to 122F. The copper-free aluminum housing, IP66 rating, and IK10 impact rating support use in demanding hazardous-location conditions.
Build Quality and Physical Characteristics
The gray fixture has a copper-free aluminum housing and tempered glass lens. It measures 16 inches in diameter by 13.5 inches high and weighs 39 pounds.
Mounting options are a yoke mount or 3/4 inch NPT pendant mount. The mounting structure and connection method must support the fixture weight and selected mounting configuration.
Where This Product Fits Best
This fixture fits hazardous classified areas requiring high-output overhead lighting, including locations with gas, vapor, dust, or fiber hazards covered by its listed classifications.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
- wastewater treatment lighting
Its IP66 rating, IK10 rating, wet-location suitability, Marine Outside Type listing, and ABS certification support installations exposed to demanding environmental conditions.
Installation and Long-Term Use
Install the fixture using the yoke or 3/4 inch NPT pendant mounting option. Verify the hazardous-location classification, supply voltage, mounting support, and control wiring before installation.
The 39-pound fixture requires a mounting point capable of supporting the installed assembly. Maintain access for inspection, cleaning, and future driver or fixture service.
How This Fixture Is Commonly Used
In hazardous location lighting and chemical processing facility lighting layouts, fixtures are positioned around mounting height, required light levels, equipment obstructions, and the 120 degree distribution. Paint booth lighting layouts also require the fixture classification and mounting method to match the area requirements.
Oil and gas facility lighting, refinery lighting, marine environment lighting, and wastewater treatment lighting installations commonly use overhead fixture layouts with pendant or yoke mounting. Spacing varies with mounting height, target light level, and the required uniformity across the selected application.
