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 light delivers 5600 lumens from 40 watts at 5000K. It is built for hazardous location lighting where a linear fixture, sealed construction, and classified-location ratings are required.
The fixture replaces 175 watt metal halide lighting while reducing connected load. Its 120 degree distribution suits broad-area illumination patterns where linear rows or individual fixtures are needed.
Core Performance and Output
The fixture produces 5600 lumens at 140 lumens per watt. The 5000K color temperature and 70+ CRI provide a cool white operating light level.
A standard 120 degree beam angle distributes light across a broad area through a tempered glass lens. At lower mounting heights, 5600 lumens can create excessive brightness if fixture placement is too dense.
Input voltage is available in 100-277V or 277-480V configurations. The fixture operates at 50-60Hz with power factor above 0.95 and THD below 10%.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming control wiring and compatible controls must match the selected voltage configuration and site requirements.
The standard optic is fixed at 120 degrees. Light distribution is controlled through mounting location, fixture orientation, and layout rather than interchangeable beam patterns.
Longevity and Reliability
Rated life is 50,000 L70 hours. The fixture is rated for operation from -22 degrees F to 122 degrees F.
The sealed IP66 enclosure and IK10 impact rating support use in demanding classified and wet-location conditions. Long-term service access should account for the 26-pound fixture weight and selected mounting method.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. A tempered glass lens protects the LED assembly.
Fixture dimensions are 47 x 5.5 x 8.1 inches. The 4-foot linear form factor supports yoke mounting or 3/4 inch NPT pendant mounting.
Where This Product Fits Best
This fixture fits classified locations, wet environments, and marine outside applications where the listed hazardous-location classifications and sealed construction match site conditions.
- hazardous location lighting
- explosion proof lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- marine environment lighting
- wastewater treatment lighting
Its IP66 rating, copper-free aluminum housing, tempered glass lens, and marine outside rating support exposed and demanding environments within its listed classifications.
Installation and Long-Term Use
The fixture mounts by yoke or 3/4 inch NPT pendant. The mounting surface or pendant system must support the 26-pound fixture weight.
Installers must select the correct 100-277V or 277-480V version for the available supply voltage. Wiring, dimming connections, and mounting hardware must be suitable for the installation conditions.
How This Fixture Is Commonly Used
In hazardous location lighting, paint booth lighting, and chemical processing facility lighting, fixtures are positioned to provide broad coverage with the 120 degree distribution. Mounting height is established from the required light levels, physical obstructions, and classified-area layout.
In oil and gas facility lighting, marine environment lighting, and wastewater treatment lighting, yoke mounting allows directional adjustment while pendant mounting supports suspended linear layouts. Spacing varies with mounting height, target light levels, and the required uniformity across the layout.
