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 is a surface-mounted connection enclosure with a built-in photocell for on/off control. It mounts on walls or ceilings and uses a standard 3/8 inch knockout.
The compact 5.6 x 5.6 x 4.2 inch housing supports hazardous location lighting and marine environment lighting installations where a photocell-controlled junction point is required. A 1/2 inch knockout is available by special order.
Core Performance and Output
This product does not produce light output. Its operating function is to provide an explosion proof junction enclosure with built-in photocell on/off functionality.
The photocell provides on/off control only. Voltage, dimming capability, fixture load capacity, and photocell switching ratings are not established by the supplied product data.
Adjustability and Control Options
The integrated photocell controls connected lighting through on/off operation. No dimming or programmable control functions are listed.
The standard configuration includes a 3/8 inch knockout. A 1/2 inch knockout configuration is available by special order.
Longevity and Reliability
The junction box carries a 5-year warranty. Its IP65 rating supports the listed wet-location and marine outside type certifications.
Long-term operation depends on correct enclosure installation, wiring practices, knockout configuration, and placement of the photocell-controlled connection point.
Build Quality and Physical Characteristics
The enclosure measures 5.6 x 5.6 x 4.2 inches. It is intended for surface mounting on a wall or ceiling.
The housing is IP65 rated and includes the photocell as part of the assembly. The compact form factor is suited to installations where the connection enclosure must remain accessible for service.
Where This Product Fits Best
This junction box fits hazardous and marine lighting installations requiring a surface-mounted connection point with photocell on/off control.
- hazardous location lighting
- explosion proof lighting
- chemical processing facility lighting
- paint booth lighting
- marine environment lighting
- oil and gas facility lighting
Its listed classifications include Class I, Class II, and Class III hazardous locations, wet locations, and marine outside type installations.
Installation and Long-Term Use
The box mounts directly to a wall or ceiling as a surface-mounted enclosure. Use the standard 3/8 inch knockout unless the 1/2 inch knockout configuration has been specified.
Mounting location should maintain access for wiring service and photocell operation. The supplied data does not establish mounting hardware, voltage, conductor capacity, or switching load limits.
How This Fixture Is Commonly Used
In hazardous location lighting, explosion proof lighting, and marine environment lighting installations, the junction box is positioned at the wall or ceiling connection point serving the controlled lighting layout. Mounting height follows the location of the connected equipment and the overall lighting layout.
Placement should account for the photocell-controlled area and required access to the enclosure. Layout requirements vary with the connected lighting equipment and site conditions.
