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 80-watt round explosion proof LED light delivers 11,200 lumens at 5000K for hazardous location lighting. Its Class I, II, and III ratings support installation where combustible gases, vapors, dusts, or fibers are present.
The fixture replaces a 250-watt metal halide while reducing connected load. Yoke and 3/4 in NPT pendant mounting support common hazardous-location mounting arrangements.
Core Performance and Output
The fixture produces 11,200 lumens at 140 lumens per watt with a 120 degree beam angle. The tempered glass lens provides broad distribution from the round high-bay form factor.
It operates on 100-277V or 277-480V, 50-60Hz power. Power factor exceeds 0.95 and total harmonic distortion is below 10%.
The 80-watt output can be excessive where mounting heights are low or where close-range task visibility is required. The standard 120 degree distribution requires layout review where higher mounting heights or tighter light control is needed.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming capability must be matched to the installed control system and wiring arrangement.
The available voltage configurations are 100-277V and 277-480V. Confirm the branch-circuit voltage before installation.
Longevity and Reliability
Rated life is 50,000 hours at L70. The fixture includes 10kV surge protection for electrical transient protection.
The operating temperature range is -22 degrees F to 122 degrees F. Long-term performance depends on maintaining the listed ambient temperature range and correctly sealing the installed mounting connection.
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 inches in diameter by 13.5 inches high. Weight is 39 pounds.
Yoke mounting provides a surface-mounted arrangement. The 3/4 in NPT pendant option supports threaded pendant installation where that mounting method is provided.
Where This Product Fits Best
This fixture fits hazardous classified areas requiring a broad 120 degree distribution, wet-location construction, and explosion proof ratings. Its 80-watt output is suited to installations replacing higher-wattage metal halide fixtures.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
IP66, marine outside type suitability, and the copper-free aluminum housing support demanding environmental conditions. Final application fit depends on the site classification and the applicable gas, dust, fiber, zone, group, and temperature code requirements.
Installation and Long-Term Use
Install the fixture using the yoke or 3/4 in NPT pendant mounting method. The 39-pound fixture weight and mounting-point condition must be considered before installation.
Verify the voltage configuration, hazardous-location classification, and mounting method before energizing the fixture. The mounting and wiring installation must maintain the required enclosure integrity.
For long-term use, inspect the tempered glass lens, housing, mounting hardware, and wiring connections during scheduled maintenance. Replace damaged components or compromised seals before returning the fixture to service.
How This Fixture Is Commonly Used
In hazardous location lighting and explosion proof lighting layouts, this fixture is typically positioned to provide broad general illumination from its 120 degree beam pattern. Mounting height and fixture placement are set around the site classification, required light levels, and obstructions.
Paint booth lighting and chemical processing facility lighting installations commonly use the yoke or pendant configuration based on available structure and fixture orientation. The broad beam angle favors open-area distribution rather than narrow directional coverage.
Spacing varies with mounting height, target light levels, and the required uniformity. Higher output can reduce fixture count, but placement must still control uneven illumination and glare.
