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 300W LED high temperature light delivers 39,000 lumens for facilities with elevated ambient temperatures. It is available in 4000K or 5000K color temperature options and operates on either 100V-277V or 347V-480V electrical systems.
The fixture is rated for operation from -40F to 194F and uses an aluminum alloy housing with an IP66 rating. Eye-hook and pendant mounting options support suspended installation.
Core Performance and Output
The fixture produces 39,000 lumens at 130 lumens per watt and is identified as a replacement for 1000W metal halide lighting. Available beam angles include 10, 25, 40, 90, and 120 degrees, allowing selection based on the required light distribution.
A polycarbonate lens protects the optical system. The fixture has a power factor greater than .95 and total harmonic distortion below 15%.
Longevity and Reliability
This high temperature LED fixture has a 70,000-hour rated lifespan and a -40F to 194F operating temperature range. Its IP66-rated aluminum alloy housing is built for demanding facility conditions.
Build Quality and Physical Characteristics
The gray fixture measures 19.6 x 16.53 x 8.65 inches and weighs 38.3 pounds. Eye-hook or pendant mounting provides suspended mounting configurations for the fixture.
