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.
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 is a simplified room utilization factor. It accounts for room 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.
Photometry / Simulation Note: When usable IES photometry is available for the selected fixture, this estimator uses the fixture’s IES candela data to improve the visual floor-level light distribution. 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. Actual light levels may vary based on fixture optics, mounting conditions, ceiling height, surface reflectance, obstructions, controls, voltage, installation conditions, and site-specific requirements.
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
The Explosion Proof Arm Bracket with Junction Box is engineered for secure and reliable mounting of explosion-proof lighting fixtures in hazardous environments. This bracket is designed to support lighting in areas where explosive gases or dust may be present, ensuring safety and compliance with stringent industry standards. With dimensions of 5.6 x 5.6 x 4.2 inches, it is compact yet robust, making it suitable for use in confined spaces such as paint booths and chemical processing facilities.
This arm bracket is compatible with our Explosion Proof EXPLA, EXPLB, EXPLC, EXPLD, and EXPLG fixtures, providing a versatile solution for various hazardous location lighting needs. Its IP67 rating ensures protection against dust and water ingress, making it ideal for both indoor and outdoor applications.
Core Performance and Output
The arm bracket is designed to withstand the rigors of hazardous environments, offering Class 1 Div 1 and Class 2 Div 1 certifications. It supports fixtures that require secure mounting in areas with explosive gases or dust. The bracket's structural integrity ensures it can handle the weight and environmental demands of explosion-proof lighting fixtures.
With its IP67 rating, the bracket provides excellent protection against dust and water, ensuring long-term durability in harsh conditions. It is important to note that while the bracket is robust, it is essential to ensure that the mounting surface can support the combined weight of the bracket and fixture.
Adjustability and Control Options
This explosion-proof arm bracket offers a fixed 25-degree mounting angle, providing optimal light distribution for targeted areas. The fixed angle ensures consistent lighting coverage, which is crucial in environments where precise illumination is required for safety and operational efficiency.
While the bracket itself does not offer adjustable angles, it is designed to work seamlessly with compatible explosion-proof fixtures that may have their own adjustability features, allowing for further customization of light direction if needed.
