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 LED high temperature UFO fixture delivers 13,000 lumens for lighting in elevated-heat industrial areas. It is available in 4000K or 5000K and operates on 100V-277V or 347V-480V power.
The fixture is rated for ambient temperatures from -40F to 194F. It replaces a 250 watt metal halide fixture where the existing environment requires a high-temperature-rated LED solution.
Core Performance and Output
This fixture produces 13,000 lumens at 130 lumens per watt. Available beam angles include 10, 25, 40, 90, and 120 degrees for concentrated or broad distribution patterns.
Power factor is greater than 0.95, THD is less than 15%, and operating frequency is 50/60 Hz. Narrow optics concentrate output for focused layouts, while wider optics spread light across larger work areas.
At lower mounting heights, the 13,000-lumen output and narrow beam options can create excessive brightness directly below the fixture. Higher mounting positions may require a wider optic to maintain uniformity.
Adjustability and Control Options
This fixture is available with 4000K or 5000K color temperature options. Beam distribution can be selected from five available optic angles.
The fixture is not dimmable. Voltage must be matched to either the 100V-277V or 347V-480V configuration.
Longevity and Reliability
Rated life is 70,000 hours. The fixture is designed for continuous operation in ambient temperatures up to 194F.
The high-temperature rating is a primary selection factor for locations where standard high bay fixtures may not tolerate the surrounding heat. Long-term performance still depends on maintaining the fixture within its stated operating temperature range.
Build Quality and Physical Characteristics
The housing is aluminum alloy with a gray finish. A polycarbonate lens protects the optical assembly.
This fixture is IP66 rated. It measures 12 x 12 x 8.65 inches and weighs 13.2 pounds.
Where This Product Fits Best
This fixture fits high-heat areas requiring a compact UFO form factor, IP66 protection, and operation up to 194F. Its 13,000-lumen output is suited to focused lighting layouts and moderate-output high-temperature installations.
- power plant and energy site lighting
- nuclear facility lighting
- industrial furnace area lighting
- boiler room lighting
- heat treatment facility lighting
- kiln lighting
The aluminum alloy housing, polycarbonate lens, and IP66 rating support installation where heat and environmental exposure are part of normal operating conditions.
Installation and Long-Term Use
Eye-hook and pendant mounting are available. The mounting structure must support the 13.2-pound fixture weight and maintain the fixture in its intended orientation.
Confirm supply voltage before installation because the fixture is offered in separate 100V-277V and 347V-480V configurations. Select the optic before installation because beam angle changes the distribution pattern.
How This Fixture Is Commonly Used
In high temperature facility lighting, industrial furnace area lighting, and boiler room lighting, fixtures are positioned based on mounting height, equipment location, and required light distribution. Eye-hook or pendant mounting allows the fixture to be suspended below structural members where needed.
Layouts commonly use narrow optics for concentrated equipment areas and wider optics for broader work zones. Higher output concentration can reduce fixture count in a focused layout but may require more attention to glare and uniformity.
Safety, Certifications, and Warranty
This fixture is ETL listed. It is IP66 rated.
The operating temperature range is -40F to 194F. The fixture includes a 5-year warranty.
