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 explosion proof LED light delivers 35,000 lumens at 5000K for hazardous classified areas requiring high-output illumination. It is available in 100V-277V or 277V-480V configurations with yoke or 3/4 inch NPT pendant mounting.
The fixture is built for hazardous location lighting, explosion proof lighting, paint booth lighting, and chemical processing facility lighting. Its 250 watt output is listed as a replacement for 1000 watt metal halide lighting.
Core Performance and Output
The fixture produces 35,000 lumens at 140 lumens per watt with a 70+ CRI. Standard distribution is 120 degrees, with 40 degree, 60 degree, and 90 degree optical options available for more controlled layouts.
Electrical performance includes 50-60Hz operation, power factor above 0.95, and THD below 10 percent. The fixture supports 1-10V dimming.
The 120 degree optic provides broad coverage where mounting height and fixture layout support a wide distribution. Higher output can reduce fixture count, but the selected optic and mounting height still determine uniformity and glare control.
Adjustability and Control Options
1-10V dimming is available for facilities using compatible dimming controls. Dimming can be used where reduced output is needed during operating conditions that do not require full light levels.
The fixture is available with 40 degree, 60 degree, 90 degree, or 120 degree beam distributions. Narrower optics concentrate output, while the standard 120 degree optic distributes light across a wider area.
Longevity and Reliability
Rated life is 50,000 hours at L70. The fixture includes 10kV surge protection for electrical transient protection.
Operating temperature range is -40F to 122F. This range supports installations exposed to low ambient temperatures, elevated ambient temperatures, or changing outdoor and industrial conditions.
Build Quality and Physical Characteristics
The housing is copper free aluminum with a gray finish. The tempered glass lens protects the optical assembly, and the fixture carries IP66 and IK10 ratings.
Fixture dimensions are 16.6 x 11.8 x 8.3 inches and weight is 32 pounds. Installation planning needs to account for fixture weight, mounting method, and access for wiring and future service.
Where This Product Fits Best
This fixture fits classified and demanding environments where hazardous location ratings, wet location suitability, and high-output illumination are required. Its construction also supports marine environment lighting and outdoor industrial exposure.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
IP66 protection, IK10 impact resistance, copper free aluminum construction, and the listed hazardous location classifications support use in exposed and industrial conditions. Final application fit depends on the area classification, voltage, mounting arrangement, and required beam distribution.
Installation and Long-Term Use
The fixture mounts by yoke or 3/4 inch NPT pendant. The selected mounting method should match the available support structure and wiring arrangement.
Verify the fixture voltage configuration before installation. The 100V-277V and 277V-480V versions address different electrical systems.
Access to the tempered glass lens, mounting hardware, and electrical connections should remain available for inspection and maintenance. The 32 pound fixture weight should be considered when preparing the mounting point.
How This Fixture Is Commonly Used
In hazardous location lighting, paint booth lighting, and chemical processing facility lighting, fixtures are positioned around the mounting height, equipment arrangement, and required light distribution. Yoke mounting allows directional aiming, while pendant mounting places the fixture below the support structure.
For oil and gas facility lighting, refinery lighting, and marine environment lighting, layouts typically use the selected optic to control how output is distributed across the work area. Mounting height and fixture placement should maintain service access and avoid obstructing process equipment.
Spacing varies with the selected beam angle, mounting height, target light level, and layout requirements. A narrower optic can concentrate output over a smaller area, while the 120 degree optic spreads output more broadly.
