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 150-watt round explosion proof LED light delivers 21,000 lumens at 5000K for hazardous location lighting, explosion proof lighting, paint booth lighting, and chemical processing facility lighting.
The fixture replaces 400-watt metal halide lighting while reducing connected load. Its round form factor uses either yoke mounting or a 3/4 in NPT pendant connection.
Core Performance and Output
This fixture produces 21,000 lumens at 140 lumens per watt. The standard 120-degree distribution supports broad coverage, with 40-degree, 60-degree, and 90-degree optical options available where beam control is needed.
It operates on 100V-277V or 277V-480V systems at 50-60Hz. Power factor is greater than 0.95 and total harmonic distortion is less than 10%.
The 150-watt output can be excessive at lower mounting heights when broad optics are used. Narrower optics concentrate output and require layout review to maintain uniform coverage.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming controls must match the selected voltage configuration and project control system.
The standard 120-degree optic provides wide distribution. Optional 40-degree, 60-degree, and 90-degree optics allow the beam pattern to be matched to the fixture layout.
Longevity and Reliability
Rated life is 50,000 hours at L70. The fixture includes 10kV surge protection.
The operating temperature range is -40 degrees F to 140 degrees F. The warranty is five years.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. A tempered glass lens protects the optical assembly.
This fixture is IP66 rated and IK10 rated. Overall dimensions are 14.56 x 11.4 inches, and fixture weight is 18.1 pounds.
Where This Product Fits Best
This fixture is intended for classified and hazardous environments requiring a high-output round luminaire. The available voltage, optical, and mounting configurations support fixed industrial lighting layouts.
- hazardous location lighting
- explosion proof lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
Its IP66 rating, IK10 rating, copper-free aluminum housing, and listed hazardous-location classifications support demanding environmental conditions. Final application fit depends on the required classification, voltage, optic, mounting arrangement, and lighting layout.
Installation and Long-Term Use
Mount the fixture with the yoke bracket or a 3/4 in NPT pendant connection. The mounting structure and connection method must support the 18.1-pound fixture weight.
Confirm the selected 100V-277V or 277V-480V configuration before installation. Use the selected optic, mounting height, and target light level to establish final fixture placement.
How This Fixture Is Commonly Used
In hazardous location lighting and explosion proof lighting layouts, fixtures are positioned around the required mounting height and beam distribution. The standard wide optic is used where broad coverage is required, while optional optics control light over more defined areas.
Paint booth lighting and chemical processing facility lighting layouts require fixture placement around equipment, work zones, and the applicable classification. Spacing varies with the selected optic, mounting height, and required light levels.
