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 150W LED high temperature light delivers 19,500 lumens for industrial locations with elevated ambient temperatures. It is designed for operation from -40°F to 194°F and is available in 100V-277V or 347V-480V configurations.

The fixture is available in 4000K or 5000K color temperatures and uses an aluminum alloy housing with a polycarbonate lens. Eye-hook and pendant mounting configurations are available.

Core Performance and Output

This fixture produces 19,500 lumens at 130 lumens per watt and is identified as a replacement for 400W metal halide lighting. Its 80+ CRI supports general industrial visibility where color rendering is needed for routine operations and maintenance.

Optional beam angles of 10, 25, 40, 90, and 120 degrees allow the fixture to be selected for concentrated or wider light distribution requirements. This model is non-dimming.

Longevity and Reliability

The LED high temperature light has a rated life of 70,000 hours and operates across a -40°F to 194°F temperature range. The IP66-rated enclosure provides protection against dust and powerful water jets.

Build Quality and Physical Characteristics

The gray aluminum alloy fixture measures 14.17 x 13.77 x 8.65 inches and weighs 19 pounds. A polycarbonate lens protects the optical system.
