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 explosion proof junction box provides a surface-mounted connection point with built-in motion sensor operation for hazardous location lighting and marine environment lighting. The motion sensor provides on/off functionality only.
The enclosure has a standard 3/4 inch knockout and a 1/2 inch knockout option by special order. Its compact 5.6 x 5.6 x 4.2 inch housing supports wall or ceiling mounting.
Core Performance and Output
This product does not produce light output. Its operating function is to provide an explosion proof junction enclosure and motion-based on/off control point.
The built-in sensor switches connected equipment on and off based on motion detection. It does not provide dimming, output adjustment, or programmable control functions.
Adjustability and Control Options
The integrated motion sensor provides basic on/off control. No dimming function is specified.
The standard connection opening is 3/4 inch. A 1/2 inch knockout configuration is available by special order.
Longevity and Reliability
The junction box carries a 5-year warranty. The IP65 enclosure rating supports use in wet locations where the listed certification requirements apply.
The enclosed construction protects internal connections and sensor components from direct exposure associated with the rated environment. Long-term performance depends on correct sealing, mounting, and wiring practices.
Build Quality and Physical Characteristics
The enclosure measures 5.6 x 5.6 x 4.2 inches. It is designed for wall or ceiling surface mounting.
The compact housing includes a built-in motion sensor and a 3/4 inch knockout as standard. Connection size should be confirmed before installation when a 1/2 inch knockout is required.
Where This Product Fits Best
This junction box fits hazardous and marine lighting systems requiring a listed enclosure with motion-based on/off operation. It is intended for locations covered by its hazardous location, wet location, and marine certifications.
- hazardous location lighting
- explosion proof lighting
- chemical processing facility lighting
- oil and gas facility lighting
- marine environment lighting
- offshore rig lighting
Its listed classifications cover Class I, Class II, and Class III locations as specified. The IP65 rating and UL 1598A Marine Outside Type listing support wet and marine exposure conditions.
Installation and Long-Term Use
Mount the junction box on a wall or ceiling where the sensor can detect movement within the intended controlled area. The mounting surface and wiring method must support the applicable hazardous location installation requirements.
Use the standard 3/4 inch knockout or confirm the 1/2 inch knockout configuration before installation. Maintain enclosure sealing and connection integrity during service work.
How This Fixture Is Commonly Used
In hazardous location lighting and explosion proof lighting systems, this enclosure is placed at the control or connection point where motion-based on/off operation is needed. Wall mounting is used where sensor orientation must cover a travel path, while ceiling mounting is used where the controlled area is below the enclosure.
Placement depends on the motion sensor detection requirement and the lighting layout. Sensor location affects when connected equipment switches on and off, so mounting position should be established before final wiring.
