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 square explosion proof LED light delivers 21,000 lumens at 5000K for hazardous location lighting. It is configured for Class I, Division 2 and Class II hazardous locations, with yoke or 3/4 in NPT pendant mounting.
The fixture replaces a 400 watt metal halide unit while reducing connected load. Its square housing, tempered glass lens, and available optics support directed lighting layouts where the standard 120 degree beam is not appropriate.
Core Performance and Output
The fixture produces 21,000 lumens at 150 watts, delivering 140 lumens per watt. It operates on 100V-277V or 277V-480V electrical systems at 50-60Hz.
A standard 120 degree beam angle is available, with optional 40 degree, 60 degree, and 90 degree optics. Narrower optics concentrate output into a smaller area, while the 120 degree optic provides broader distribution.
Power factor is greater than 0.95 and total harmonic distortion is below 10%. The 21,000-lumen output can be excessive where mounting height is low or the lighted area is limited.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming wiring and control compatibility should be confirmed as part of the project electrical design.
Available beam angles allow the distribution to be matched to the layout. The standard 120 degree optic is broad, while 40 degree, 60 degree, and 90 degree options provide tighter control of the light pattern.
Longevity and Reliability
The rated life is 50,000 hours at L70. The fixture includes 10kV surge protection for electrical transient protection.
Operating temperature range is -40 deg F to 122 deg F. The five-year warranty applies to the fixture.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. A tempered glass lens protects the optical assembly.
The fixture is IP66 rated and IK10 rated. Overall dimensions are 14.9 x 9.1 x 10.6 inches, and fixture weight is 26 pounds.
Where This Product Fits Best
This fixture is intended for hazardous environments requiring a listed explosion proof LED lighting product. Its hazardous-location classifications, wet-location suitability, and available mounting options support fixed installations in classified areas.
- hazardous location lighting
- explosion proof lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
IP66 protection, IK10 impact resistance, copper-free aluminum construction, and operation from -40 deg F to 122 deg F support demanding environmental conditions. Final application fit depends on the area classification, voltage, mounting arrangement, and required light distribution.
Installation and Long-Term Use
The fixture mounts by yoke or 3/4 in NPT pendant. The 26-pound fixture weight and selected mounting method should be accounted for before installation.
Input voltage must match either the 100V-277V or 277V-480V configuration. Confirm the area classification and installation requirements before energizing the fixture.
How This Fixture Is Commonly Used
In hazardous location lighting and paint booth lighting layouts, the fixture is positioned around the mounting height and required light distribution for the work area. Yoke mounting supports aimed installation, while 3/4 in NPT pendant mounting supports suspended placement.
For chemical processing facility lighting, oil and gas facility lighting, and refinery lighting, fixture placement follows the classified-area layout and the selected beam angle. Spacing varies with mounting height, target light levels, and whether the standard or optional optic is used.
Marine environment lighting installations should account for the fixture’s mounting method, electrical configuration, and IP66 rating. The 120 degree optic provides broader coverage, while narrower optics reduce spread and concentrate the available output.
