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 300W square explosion proof LED light delivers 42,000 lumens at 5000K for hazardous location lighting, explosion proof lighting, paint booth lighting, and chemical processing facility lighting. It is available in 100V-277V or 277V-480V configurations.
The fixture uses a copper-free aluminum housing, tempered glass lens, and sealed IP66 construction. Yoke and 3/4 in NPT pendant mounting support different fixture orientations and mounting arrangements.
Core Performance and Output
The fixture produces 42,000 lumens at 300W, delivering 140 lumens per watt. It has a 5000K color temperature, 70+ CRI, power factor above 0.95, and total harmonic distortion below 10%.
A standard 120 degree beam angle is available, with 40 degree, 60 degree, and 90 degree optical options. Narrower optics concentrate output for longer throw patterns, while the 120 degree distribution covers broader areas.
This output level can be excessive in low mounting positions. Higher mounting positions require optical and layout review to maintain uniform light distribution.
Adjustability and Control Options
This fixture supports 1-10V dimming. Dimming control wiring and control compatibility must match the installed electrical system.
The available beam angles allow the light distribution to be matched to the mounting arrangement. The yoke mount allows directional adjustment, while the 3/4 in NPT pendant mount supports a fixed suspended installation.
Longevity and Reliability
The LED system is rated for 50,000 L70 hours. The fixture includes 10kV surge protection for electrical transient resistance.
Its operating temperature range is -40F to 122F. The copper-free aluminum housing, tempered glass lens, IP66 rating, and IK10 impact rating support long-term use in demanding conditions.
Build Quality and Physical Characteristics
The gray fixture housing is constructed from copper-free aluminum and uses a tempered glass lens. It measures 16.6 x 11.8 x 8.3 inches and weighs 32 pounds.
Installation requires support for the fixture weight and the selected mounting method. The yoke and 3/4 in NPT pendant options should be coordinated with the mounting structure and electrical entry method.
Where This Product Fits Best
This fixture fits hazardous classified lighting installations requiring high output, sealed construction, and approved hazardous location ratings. Its available mounting and optical configurations support different lighting layouts within these applications.
- hazardous location lighting
- chemical processing facility lighting
- paint booth lighting
- explosion proof lighting
- oil and gas facility lighting
- refinery lighting
IP66, IK10, wet location suitability, marine outside type suitability, and the listed hazardous location classifications support use where the installation conditions match the fixture ratings.
Installation and Long-Term Use
The fixture installs with either a yoke mount or a 3/4 in NPT pendant mount. Voltage selection must match either the 100V-277V or 277V-480V fixture configuration.
The 32-pound fixture weight, mounting structure, electrical entry, and dimming connections should be reviewed before installation. The housing and lens should remain accessible for inspection and cleaning during long-term service.
How This Fixture Is Commonly Used
In hazardous location lighting and chemical processing facility lighting, fixture mounting height and beam angle are coordinated with the required illumination pattern. Yoke mounting is used where directional aiming is needed, while pendant mounting supports suspended layouts.
Paint booth lighting and refinery lighting layouts use fixture placement to manage light distribution across the intended work area. Spacing varies with the selected beam angle, mounting height, and required light level.
Higher output can reduce fixture count in a layout, but narrow optical distributions require more deliberate aiming and placement. The selected voltage and control wiring must match the installed system.
