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 300 watt round explosion proof LED light delivers 42,000 lumens at 5000K for hazardous location lighting. It is built for Class I, II, and III classified locations requiring a sealed, high-output fixture.
The fixture supports 100V-277V or 277V-480V input voltage and replaces a 1000 watt metal halide fixture. Yoke and 3/4 inch NPT pendant mounting support different structural mounting conditions.
Core Performance and Output
The fixture produces 42,000 lumens at 140 lumens per watt. A 120 degree beam angle is standard, with 40 degree, 60 degree, and 90 degree optical options available for more controlled distribution.
Electrical performance includes 50-60Hz operation, power factor above 0.95, THD below 10 percent, and 1-10V dimming. The 300 watt output can be excessive where mounting heights are low or where a narrower distribution is required.
Adjustability and Control Options
1-10V dimming is included for applications using compatible dimming controls. Dimming can reduce output where full 42,000-lumen operation is not required.
Optical selection is available through 40 degree, 60 degree, and 90 degree beam angles. The standard 120 degree distribution provides broad coverage, while narrower optics concentrate output over a smaller area.
Longevity and Reliability
The LED system is rated for 50,000 L70 hours. A 10kV surge protection device is included to address electrical surge exposure.
The operating temperature range is -40F to 140F. The fixture includes a five-year warranty.
Build Quality and Physical Characteristics
The housing is copper-free aluminum with a gray finish. A tempered glass lens protects the optical system, and the enclosure is rated IP66.
The fixture measures 18.9 by 15.5 inches and weighs 37.5 pounds. Mounting structure and hardware need to support the fixture weight and the selected yoke or 3/4 inch NPT pendant configuration.
Where This Product Fits Best
This fixture is intended for classified and hazardous operating areas where high output, sealed construction, and hazardous location listings are required. Its output level is aligned with large-area hazardous lighting layouts.
- hazardous location lighting
- explosion proof lighting
- chemical processing facility lighting
- paint booth lighting
- oil and gas facility lighting
- refinery lighting
- marine environment lighting
- offshore rig lighting
IP66 construction supports wet location conditions. UL 1598A Marine Outside Type, ABS, ATEX, and IECEx markings support projects requiring those listed classifications.
Installation and Long-Term Use
The fixture installs using a yoke mount or a 3/4 inch NPT pendant mount. Confirm the selected mounting method, fixture weight, voltage range, and control wiring before installation.
Use the 100V-277V or 277V-480V version that matches the available electrical system. Allow access for inspection, cleaning, and future fixture service without disturbing classified-area installation requirements.
How This Fixture Is Commonly Used
Mounting height should be established from the required light level, selected beam angle, and layout for the applicable hazardous location lighting project. The 120 degree optic is used for broad distribution, while 40 degree, 60 degree, and 90 degree options allow more focused layouts.
Fixture spacing follows the mounting height, optical selection, and target uniformity. Higher output can reduce fixture count, but it can also require tighter optical control to manage distribution across the layout.
