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 100 watt square LED explosion proof light delivers 14,000 lumens at 5000K for classified hazardous locations. It is built for fixed mounting where hazardous-location ratings, wet-location suitability, and impact resistance are required.
The fixture replaces a 250 watt metal halide unit while reducing connected load. Yoke and 3/4 inch NPT pendant mounting support different structural mounting conditions.
Core Performance and Output
The fixture produces 14,000 lumens at 140 lumens per watt. The 5000K color temperature and 70+ CRI provide a cool white output suitable for operational visibility.
A 120 degree beam angle is standard. Optional 40 degree, 60 degree, and 90 degree optics allow the distribution to be matched to the mounting position and layout.
The fixture operates on 100V-277V or 277V-480V input and supports 1-10V dimming. Power factor is greater than 0.95 and THD is less than 10 percent.
The 14,000-lumen output can be excessive at low mounting heights without an appropriate optic or dimming plan. Narrower optics require closer attention to fixture aiming and layout uniformity.
Adjustability and Control Options
1-10V dimming is available for applications using compatible control equipment. Dimming can be used to adjust output after commissioning when the installed light level is higher than required.
The standard 120 degree distribution provides broad coverage. Optional 40 degree, 60 degree, and 90 degree optics provide more controlled distributions for layouts that require tighter light placement.
Longevity and Reliability
The LED system is rated for 50,000 hours L70 life. The fixture includes 10kV surge protection.
Operating temperature range is -40 degrees F to 122 degrees F. This range supports installations exposed to cold or elevated ambient conditions within the stated limits.
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 rated IP66 and IK10. It measures 12.5 by 9.5 by 6.5 inches and weighs 26 pounds.
Yoke mounting provides a fixed surface-mounted arrangement. The 3/4 inch NPT pendant option supports threaded conduit mounting where that mounting method is part of the fixture installation.
Where This Product Fits Best
This fixture fits classified and hazardous environments requiring a compact 100 watt explosion proof fixture with broad or controlled optical distributions.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- marine environment lighting
- wastewater treatment lighting
Its IP66 rating, wet-location suitability, marine outside type rating, and -40 degrees F to 122 degrees F operating range support demanding environmental conditions within the published ratings.
Installation and Long-Term Use
Verify the area classification, available voltage, mounting structure, and selected optic before installation. The fixture is available in 100V-277V and 277V-480V configurations.
The 26 pound fixture requires mounting hardware and structure appropriate for its installed weight. Use either the yoke or 3/4 inch NPT pendant mounting method supplied for the selected configuration.
For long-term service, inspect the tempered glass lens, mounting points, conduit entry, and external housing condition during routine maintenance. Maintain the fixture within its stated operating temperature range.
How This Fixture Is Commonly Used
In hazardous location lighting and explosion proof lighting layouts, the fixture is positioned at mounting heights established by the facility layout, required light levels, and selected beam angle. The 120 degree optic is used where broad distribution is needed, while optional optics control light placement in more focused layouts.
Paint booth lighting, chemical processing facility lighting, and oil and gas facility lighting layouts require the mounting method and voltage configuration to match site conditions. Fixture placement is coordinated with the classified-area requirements and access for maintenance.
Marine environment lighting and wastewater treatment lighting installations require attention to mounting condition and fixture access. Higher output can reduce fixture count, but the final layout must maintain the required uniformity.
