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 square explosion proof LED light is designed for hazardous location lighting where classified-area ratings, wet-location protection, and durable construction are required. It produces 11,200 lumens at 5000K and is available in 100V-277V or 277V-480V configurations.
The fixture is used for hazardous location lighting, explosion proof lighting, paint booth lighting, and chemical processing facility lighting. Its 120 degree standard beam angle supports broad distribution, while 40, 60, and 90 degree optics are available where a narrower pattern is required.
Core Performance and Output
This fixture delivers 11,200 lumens at 140 lumens per watt. The 80 watt LED system replaces a 250 watt metal halide fixture.
Standard output uses a 120 degree beam angle with a tempered glass lens. Optional 40, 60, and 90 degree beam angles allow the distribution pattern to match the installation layout.
The driver operates at 50-60Hz with a power factor greater than 0.95 and total harmonic distortion below 10 percent. The 11,200 lumen output can be excessive where mounting height is low or where close fixture spacing is required.
Adjustability and Control Options
This explosion proof fixture supports 1-10V dimming. Dimming can be used where the installation includes compatible 1-10V control equipment.
Voltage selection must match the available electrical system. Available configurations are 100V-277V and 277V-480V.
Longevity and Reliability
The LED system is rated for 50,000 L70 hours. The fixture includes 10kV surge protection.
Operating temperature is -22F to 122F. The five-year warranty applies to the fixture.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. The fixture measures 12.5 x 9.5 x 6.5 inches and weighs 26 pounds.
An IP66 rating supports wet-location exposure. The IK10 rating provides impact resistance, and the tempered glass lens protects the optical assembly.
Where This Product Fits Best
This fixture fits classified and hazardous operating areas where its Class I, Class II, Class III, ATEX, and IECEx markings match project requirements. It is also suited to wet and marine outside installations within the listed applications.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
- wastewater treatment lighting
The IP66, IK10, copper-free aluminum, and marine outside type construction address exposed and demanding installation conditions. Final application fit depends on the applicable area classification, voltage, optic, mounting method, and layout.
Installation and Long-Term Use
The fixture mounts by yoke or 3/4 inch NPT pendant connection. The 26 pound fixture weight and selected mounting method must be accounted for in the installation structure.
Installers must match the fixture voltage configuration to the available supply voltage. The dimming connection requires compatible 1-10V controls when dimming is used.
Long-term maintenance should include inspection of the lens, housing, mounting connection, and electrical connections. The IP66 enclosure and tempered glass lens support routine service in wet-location conditions.
How This Fixture Is Commonly Used
In hazardous location lighting and explosion proof lighting layouts, the fixture is positioned to provide the required distribution across the classified area. Yoke mounting allows directional aiming, while 3/4 inch NPT pendant mounting supports suspended installation arrangements.
Paint booth lighting, chemical processing facility lighting, refinery lighting, and wastewater treatment lighting layouts require the selected optic to match mounting height and fixture placement. The 120 degree optic supports broad coverage, while narrower optics concentrate output into a smaller area.
Fixture spacing varies with mounting height, selected beam angle, target light level, and layout requirements. Higher output can reduce fixture count, but it can also increase glare when fixtures are mounted too low or placed too closely together.
