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 50-watt LED high temperature light delivers 7,500 lumens at 5000K for elevated-temperature industrial lighting conditions. It is built with an aluminum alloy housing, tempered glass lens, and pendant mounting configuration.
The fixture operates from -40F to 302F and is suited to locations where standard high bay fixtures may not tolerate sustained heat exposure. Its 50-watt output replaces a 250-watt metal halide fixture.
Core Performance and Output
This fixture produces 7,500 lumens at 150 lumens per watt. The 120-degree beam angle provides a broad distribution from a pendant-mounted position.
It operates on 100-277V, 50/60 Hz power with a power factor above 0.95 and THD below 15%. The 7,500-lumen output can be excessive where mounting height is low or where concentrated task-area lighting is required.
The broad 120-degree distribution supports wider coverage, but uniformity depends on the mounting height and fixture layout. Higher mounting positions may require layout review to maintain light levels between fixtures.
Adjustability and Control Options
This fixture has a fixed 50-watt output and is not dimmable. It operates at a fixed 5000K color temperature with a CRI of 75+.
The standard optic is a tempered glass lens with a 120-degree beam angle. No alternate beam angles or control options are listed for this configuration.
Longevity and Reliability
The LED system is rated for 100,000 hours L70 life. This rating supports long operating intervals in high temperature facility lighting and other heat-exposed industrial areas.
A 6kV surge protection rating is included. The fixture carries a 5-year warranty.
Build Quality and Physical Characteristics
The housing is aluminum alloy with a silver finish. A tempered glass lens protects the optical assembly.
The fixture is IP66 rated and measures 12 x 10.5 x 2.5 inches. It weighs 11 pounds and uses pendant mounting.
Where This Product Fits Best
This fixture fits elevated-temperature industrial areas where the operating environment can reach up to 302F. Its pendant mount, broad beam pattern, and high-temperature operating range align with heat-exposed lighting locations.
- industrial furnace area lighting
- power plant and energy site lighting
- nuclear facility lighting
- high temperature facility lighting
- boiler room lighting
- heat treatment facility lighting
- kiln lighting
The IP66-rated enclosure and tempered glass lens support use where dust and water ingress protection are required. Final suitability depends on actual ambient temperature at the fixture location and the pendant mounting arrangement.
Installation and Long-Term Use
Pendant mounting requires a suitable overhead mounting point and support for the 11-pound fixture. The installation location must keep the fixture within its stated -40F to 302F operating temperature range.
Verify the available supply voltage is within the listed 100-277V range before installation. The fixture is non-dimmable, so it should be connected only where fixed-output operation is required.
How This Fixture Is Commonly Used
In industrial furnace area lighting, boiler room lighting, and heat treatment facility lighting, fixtures are pendant-mounted below the available overhead structure. Mounting height is established around the heat source, structural conditions, and required light distribution.
Layouts use the 120-degree beam pattern to distribute light across the selected area. Spacing varies with mounting height, target light levels, and the 7,500-lumen output.
For power plant and energy site lighting, nuclear facility lighting, and kiln lighting, fixture placement should account for the measured ambient temperature at the installed location. The 302F maximum operating temperature applies to the fixture environment, not only the nearby process temperature.
Safety, Certifications, and Warranty
This fixture is ETL listed. It is IP66 rated.
The operating temperature range is -40F to 302F. The fixture includes 6kV surge protection and a 5-year warranty.
