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.

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 150-watt LED high temperature light is a UFO-style fixture built for areas exposed to sustained heat. It produces 19,500 lumens and operates in ambient temperatures from -40F to 194F.

The fixture is configured for high temperature facility lighting where conventional high bay fixtures may not tolerate the ambient conditions. It is available with 100V-277V or 347V-480V input and 4000K or 5000K color temperature options.

Core Performance and Output

The fixture delivers 19,500 lumens at 150 watts, producing 130 lumens per watt. It has an 80+ CRI, power factor above 0.95, and THD below 15%.

Available beam angles include 10-degree, 25-degree, 40-degree, 90-degree, and 120-degree distributions. Narrow optics concentrate output while wider optics distribute light across a broader area.

The 19,500-lumen output can be excessive at lower mounting heights when wide-area coverage is not required. Beam angle selection affects uniformity, glare, and fixture layout.

Adjustability and Control Options

This fixture is non-dimming. It operates on 50/60 Hz power and is available in 100V-277V or 347V-480V voltage configurations.

Optical distribution is selected through the available beam angle options. The fixture does not include field dimming capability.

Longevity and Reliability

The rated lifespan is 70,000 hours. The fixture is designed for operation in ambient temperatures from -40F to 194F.

High temperature applications require confirmation of the actual ambient temperature at the fixture location. Heat conditions can vary between open work areas and locations close to process equipment.

Build Quality and Physical Characteristics

The fixture uses an aluminum alloy housing, polycarbonate lens, and gray finish. It measures 14.17 x 13.77 x 8.65 inches and weighs 19 pounds.

IP66 protection supports use in demanding industrial conditions. Eye-hook and pendant mounting options are available.

Where This Product Fits Best

This fixture fits enclosed or sheltered industrial areas where high ambient temperature is a primary equipment condition. Its 194F operating rating is relevant where heat exposure is sustained around the fixture.

  • power plant and energy site lighting
  • industrial furnace area lighting
  • steel mill lighting
  • foundry lighting
  • nuclear facility lighting
  • boiler room lighting
  • kiln lighting
  • heat treatment facility lighting

The aluminum alloy housing, polycarbonate lens, and IP66 rating support installations exposed to industrial dust and moisture. Actual ambient temperature and voltage must match the fixture configuration.

Installation and Long-Term Use

Eye-hook mounting suits suspended installation points, while pendant mounting supports fixed downrod configurations. The mounting structure must support the 19-pound fixture weight.

Confirm the selected voltage before installation. Electrical connections and mounting components should remain outside conditions that exceed the fixture’s -40F to 194F operating range.

How This Fixture Is Commonly Used

In power plant and energy site lighting, steel mill lighting, foundry lighting, and industrial furnace area lighting, fixtures are installed above the active heat zone where mounting structure and temperature conditions permit. Layouts use the selected beam angle to direct output toward work areas and equipment zones.

For boiler room lighting, kiln lighting, nuclear facility lighting, and heat treatment facility lighting, mounting height is determined by available structure, heat exposure, and required light distribution. Wider optics can reduce fixture concentration, while narrow optics place more output into a defined area.

Spacing varies with mounting height, beam angle, target light level, and the location of heat-generating equipment. Higher output can reduce fixture count, but concentrated optics may require more careful aiming and layout review.

Safety, Certifications, and Warranty

This fixture is ETL listed and IP66 rated. It has a 5-year warranty.

The operating temperature range is -40F to 194F. The fixture is available in 100V-277V or 347V-480V configurations.
