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 100-watt round explosion proof LED light delivers 14,000 lumens at 5000K for hazardous location lighting, explosion proof lighting, paint booth lighting, and chemical processing facility lighting. It is available in 100-277V or 277-480V configurations.
The fixture replaces a 250-watt metal halide fixture and uses a 120-degree beam distribution. Yoke and 3/4-inch NPT pendant mounting support different fixture positioning requirements.
Core Performance and Output
The fixture produces 14,000 lumens at 140 lumens per watt. Its 5000K color temperature and 70+ CRI provide a neutral white output for industrial hazardous locations.
A 120-degree beam angle supports broad distribution from overhead mounting locations. This output can be excessive at low mounting heights, while higher mounting locations may require closer layout review to maintain uniformity.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming control wiring should be planned with the selected voltage configuration and hazardous-location installation requirements.
The fixture is available with a yoke mount or 3/4-inch NPT pendant mount. The mounting method affects aiming, fixture orientation, and final layout flexibility.
Longevity and Reliability
The rated life is 50,000 hours at L70. The fixture includes 10kV surge protection and operates from -22 degrees F to 122 degrees F.
A power factor above 0.95 and total harmonic distortion below 10 percent support electrical performance on 50-60Hz systems. Long-term operation depends on maintaining the fixture, mounting components, and electrical connections in serviceable condition.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. A tempered glass lens protects the optical assembly.
This fixture is rated IP66 and IK10. It measures 16 by 13.5 inches and weighs 39 pounds, so the mounting location and support method must accommodate the fixture weight.
Where This Product Fits Best
This fixture fits hazardous and classified environments where explosion proof lighting construction, wet-location suitability, and durable enclosure protection are required. The 100-watt output suits installations needing a moderate-output round fixture.
- hazardous location lighting
- explosion proof lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- solvent storage area lighting
Its IP66 rating, IK10 rating, marine outside type listing, and operating temperature range support demanding environmental conditions covered by its listed classifications.
Installation and Long-Term Use
Install the fixture using the yoke mount or 3/4-inch NPT pendant mount. Confirm the selected voltage version, mounting support, and fixture orientation before installation.
The 39-pound fixture requires secure mounting hardware and support structure. Access for future inspection, cleaning, and electrical service should be considered during layout planning.
How This Fixture Is Commonly Used
In hazardous location lighting and explosion proof lighting layouts, fixtures are mounted overhead using pendant or yoke mounting based on the available structure and required aiming. Paint booth lighting and chemical processing facility lighting installations use the 120-degree distribution to establish broad light coverage.
Fixture spacing and layout depend on mounting height, target light levels, and the selected mounting method. Higher output can reduce fixture count, but layout review is needed to control glare and maintain uniformity.
