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 400 watt LED high temperature light produces 52,000 lumens for facilities with sustained elevated ambient temperatures. It is rated for operation from -40F to 194F and uses an aluminum alloy housing with a polycarbonate lens.
The fixture is configured for eye-hook or pendant mounting and is available in 100V-277V or 347V-480V input voltage versions. It is commonly considered for power plant and energy site lighting, nuclear facility lighting, and industrial furnace area lighting.
Core Performance and Output
This fixture delivers 52,000 lumens at 130 lumens per watt. It is available in 4000K or 5000K with an 80+ CRI and is listed as replacing a 1000 watt metal halide fixture.
Available beam angles include 10, 25, 40, 90, and 120 degrees. Narrow beam options require more precise aiming, while wider optics distribute output across a broader area.
The fixture operates on 50/60 Hz power with a power factor above 0.95 and THD below 15%. Its output can be excessive at low mounting heights, particularly when narrow optics are selected.
Adjustability and Control Options
This fixture is available with 4000K or 5000K color temperature options. Voltage configurations include 100V-277V and 347V-480V.
Optical selection is available from 10 degree through 120 degree beam angles. The fixture does not include dimming.
Longevity and Reliability
The rated lifespan is 70,000 hours. The fixture carries a 5-year warranty.
Its -40F to 194F operating temperature range supports high temperature facility lighting where standard high bay fixtures may not be rated for the ambient conditions.
Build Quality and Physical Characteristics
The housing is aluminum alloy with a gray finish. A polycarbonate lens protects the optical assembly.
The fixture is IP66 rated. It measures 22 x 20.86 x 8.65 inches and weighs 45.8 pounds.
Where This Product Fits Best
This high temperature fixture fits industrial locations where elevated ambient temperature is a documented operating condition. Its 52,000-lumen output and high-temperature rating align with larger industrial lighting layouts.
- power plant and energy site lighting
- nuclear facility lighting
- industrial furnace area lighting
- steel mill lighting
- foundry lighting
- boiler room lighting
The IP66 rating, aluminum alloy housing, and operating temperature rating support use in demanding industrial environments. Final fixture placement should account for actual ambient temperature at the mounting location.
Installation and Long-Term Use
Installation uses either an eye-hook or pendant mounting configuration. The supporting structure must accommodate the 45.8-pound fixture weight and the selected mounting arrangement.
Voltage must match the specified 100V-277V or 347V-480V fixture version. The fixture is non-dimming, so control planning should not assume dimming capability.
How This Fixture Is Commonly Used
In power plant and energy site lighting, industrial furnace area lighting, and steel mill lighting, fixtures are positioned around the mounting height and layout required for the work area. Eye-hook and pendant mounting allow the fixture to be suspended from suitable overhead structure.
Beam angle selection affects spacing and aiming patterns. Narrow optics concentrate the 52,000-lumen output, while 90 degree and 120 degree optics spread light across a wider layout.
In foundry lighting and boiler room lighting, fixture placement must account for the actual temperature at the installed location. Mounting height, beam angle, and required light distribution should be established before layout is finalized.
Safety, Certifications, and Warranty
This fixture is ETL listed.
It is IP66 rated and carries a 5-year warranty.
