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 at 5000K for industrial areas exposed to sustained heat. It is rated for operation from -40F through 176F.
The fixture is used where conventional high bays face elevated ambient temperatures, including power plant and energy site lighting, steel mill lighting, and industrial furnace area lighting. It replaces 250 watt metal halide fixtures where the existing electrical and mounting conditions are compatible.
Core Performance and Output
The fixture produces 13,000 lumens at 130 lumens per watt. The standard 110 degree distribution supports broad illumination, while 30 degree, 90 degree, and 150 degree beam options are available for layouts requiring a narrower or wider distribution.
Input voltage is available in 100V-277V or 277V-480V configurations at 50/60Hz. Power factor is 0.95 and total harmonic distortion is 20 percent maximum.
At lower mounting heights, 13,000 lumens can create excessive brightness if fixture placement is not controlled. Narrower beam options concentrate output, while wider optics require attention to edge light levels and overlap.
Adjustability and Control Options
This fixture is non-dimming. It operates at its rated output when energized.
Beam distribution can be selected as 30 degrees, 90 degrees, 110 degrees, or 150 degrees. The standard optic is 110 degrees.
Longevity and Reliability
Rated life is 100,000 hours at L70. The fixture includes 12kV surge protection for electrical transient resistance.
The operating temperature range extends from -40F to 176F. This rating is central to its use in high temperature facility lighting and heat-intensive industrial areas.
Build Quality and Physical Characteristics
The housing is die-cast aluminum with a gray finish. A polycarbonate lens protects the optical assembly.
The fixture is IP66 rated and IK10 rated. Dimensions are 12.1 inches long by 14.4 inches wide by 9.6 inches high, and fixture weight is 17.2 pounds.
Where This Product Fits Best
This high temperature fixture fits industrial locations where elevated ambient heat, dust exposure, and physical impact resistance affect fixture selection. Its 176F operating temperature rating supports applications with sustained heat near process equipment.
- power plant and energy site lighting
- industrial furnace area lighting
- steel mill lighting
- foundry lighting
- boiler room lighting
- heat treatment facility lighting
IP66 and IK10 ratings support installations requiring resistance to dust, water ingress, and impact. Final fixture placement must account for ambient temperature at the mounting location, not only the general building temperature.
Installation and Long-Term Use
Mounting is available with an eye-hook or trunnion. The selected mounting method must support the 17.2 pound fixture weight and maintain the intended aiming position.
Eye-hook mounting suits suspended layouts. Trunnion mounting provides fixed directional adjustment where the fixture must be aimed toward the work area or equipment zone.
Verify the installed voltage configuration before connection. The fixture is not dimmable, so control plans requiring reduced output need to be resolved before installation.
How This Fixture Is Commonly Used
In power plant and energy site lighting, industrial furnace area lighting, steel mill lighting, and foundry lighting, fixtures are positioned according to the heat profile, mounting height, and required light distribution. Mounting location must remain within the -40F to 176F operating range.
Layouts commonly use the standard 110 degree optic for broad coverage or optional optics where the illuminated area is more concentrated or more open. Spacing and fixture count vary with mounting height, beam angle, target light level, and the physical arrangement of process equipment.
Safety, Certifications, and Warranty
This fixture is ETL certified.
It has an IP66 rating, IK10 rating, and 12kV surge protection. Warranty coverage is 5 years.
