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 4-foot explosion proof linear LED fixture delivers 5,600 lumens at 40W with a 5000K color temperature. It is built for hazardous location lighting where a linear form factor, wet-location construction, and Class I, II, or III hazardous-location classifications are required.
The fixture is available in 100-277V or 277-480V configurations and supports 1-10V dimming. A 120-degree beam angle provides broad light distribution through a tempered glass lens.
Core Performance and Output
With 140 lumens per watt, this fixture provides LED output comparable to a 175W metal halide fixture. The 5000K light color and 70+ CRI support clear general-purpose illumination in hazardous industrial and processing areas.
The driver operates at 50-60Hz with power factor greater than 0.95 and total harmonic distortion below 10%.
Longevity and Reliability
The LED system is rated for 50,000 L70 hours. Its copper-free aluminum housing, IP66 rating, IK10 impact rating, and tempered glass lens support use in demanding wet and industrial environments.
This fixture is rated for operation from -22 degrees F to 122 degrees F and carries a 5-year warranty.
Build Quality and Physical Characteristics
The gray linear housing measures 47 x 5.5 x 8.1 inches and weighs 26 lb. Mounting options include a yoke mount or 3/4 inch NPT pendant mount.
