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 is a hazardous-location fixture with 21,000 lumens of 5000K light output. It is configured for Class I, II, and III hazardous locations within its listed classifications.
The fixture replaces a 400-watt metal halide system and uses a copper-free aluminum housing, tempered glass lens, and sealed IP66 construction. Yoke and 3/4 in NPT pendant mounting support common fixed mounting arrangements.
Core Performance and Output
The fixture produces 21,000 lumens at 150 watts for 140 lumens per watt. Its 5000K color temperature and 70+ CRI provide a cool white output for hazardous location lighting and paint booth lighting.
A standard 120-degree beam angle provides broad downward distribution. At lower mounting heights, this output can be excessive without a layout matched to the area. At higher mounting heights, uniformity depends on fixture placement and the required light level.
The fixture operates on either 100V-277V or 277V-480V at 50-60Hz. Power factor is greater than 0.95, and total harmonic distortion is less than 10%.
Adjustability and Control Options
This fixture supports 1-10V dimming. Control wiring and dimming compatibility need to match the installed control system.
The light output is fixed at 150 watts and 21,000 lumens. The standard optical distribution is 120 degrees.
Longevity and Reliability
Rated life is 50,000 hours at L70. The fixture includes 10kV surge protection.
The operating temperature range is -22 degrees F to 122 degrees F. Long-term performance depends on maintaining the sealed enclosure, electrical connections, and mounting hardware.
Build Quality and Physical Characteristics
The gray housing is copper-free aluminum with a tempered glass lens. The fixture is IP66 rated and IK10 rated.
Fixture dimensions are 16 x 13.5 inches, and weight is 39 pounds. The mounting structure must support the fixture weight and the selected yoke or 3/4 in NPT pendant arrangement.
Where This Product Fits Best
This fixture fits classified locations where the listed hazardous-location ratings, wet-location suitability, and sealed construction match site conditions. Its 21,000-lumen output is suited to larger work areas requiring broad overhead distribution.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- explosion proof lighting
- oil and gas facility lighting
- refinery lighting
- solvent storage area lighting
The fixture is rated for wet locations and marine outside type use. Application fit must remain within the listed Class, Division, Group, ATEX, and IECEx markings.
Installation and Long-Term Use
Install the fixture using the yoke or 3/4 in NPT pendant mount. The 39-pound fixture weight, mounting orientation, and wiring method need to be addressed before installation.
Select the 100V-277V or 277V-480V configuration to match the available supply voltage. Hazardous-location installation must follow the applicable electrical requirements and the fixture’s listed classifications.
How This Fixture Is Commonly Used
In hazardous location lighting and chemical processing facility lighting, the fixture is mounted overhead using the selected yoke or pendant method. Mounting height is determined by the facility layout, target light level, and required equipment clearance.
Paint booth lighting and refinery lighting layouts typically use the 120-degree distribution to create broad coverage across the defined work area. Spacing varies with mounting height, required light levels, and the need to control overlap between fixtures.
For oil and gas facility lighting and solvent storage area lighting, fixture placement must align with the applicable classified area boundaries and the listed fixture classification.
