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 wall or ceiling mounting point for hazardous location lighting and marine environment lighting. It is available with 1/2 inch or 3/4 inch NPT connections and includes a built-in motion sensor.
The unit operates on 100V-277V and is intended for installations requiring Class I, II, or III hazardous location classifications. Its compact 5.6 x 5.6 x 4.2 inch housing supports enclosed electrical connections where a wall or ceiling-mounted junction box is required.
Core Performance and Output
This product is a junction box and does not produce light output or beam distribution. Electrical operation is rated for 100V-277V, and the built-in motion sensor is included within the assembly.
Lighting output, beam pattern, fixture spacing, and mounting height depend on the connected lighting equipment and project layout. The supplied product data does not establish fixture coverage or spacing values.
Adjustability and Control Options
A built-in motion sensor is included. No separate dimming, photocell, timer, or control compatibility information is established by the supplied data.
The junction box is available with 1/2 inch or 3/4 inch NPT connections. Final connection selection must match the installation requirements and connected equipment.
Longevity and Reliability
This junction box is rated for a 50,000-hour lifespan. It carries a 5-year warranty.
The IP65 rating supports use in wet locations where the installation conditions remain within the listed product ratings. Long-term performance depends on maintaining the enclosure and electrical connections during service work.
Build Quality and Physical Characteristics
The enclosure measures 5.6 x 5.6 x 4.2 inches. It is configured for wall or ceiling mounting.
The housing is IP65 rated and includes the motion sensor as part of the assembly. The physical size should be reviewed against available mounting space and conduit routing before installation.
Where This Product Fits Best
This junction box fits hazardous location lighting installations that require a wall or ceiling-mounted electrical enclosure. It also fits marine environment lighting where wet-location and marine outside type listings are required.
- hazardous location lighting
- explosion proof lighting
- marine environment lighting
- oil and gas facility lighting
- refinery lighting
- wastewater treatment lighting
Its listed hazardous location classifications, IP65 rating, wet-location listing, and marine outside type listing define the supported environmental conditions. Installation conditions must remain consistent with the applicable classification and enclosure ratings.
Installation and Long-Term Use
The junction box mounts on a wall or ceiling and uses either 1/2 inch or 3/4 inch NPT connections. Installation must account for enclosure access, conduit routing, and placement of the built-in motion sensor.
Mounting height follows the connected hazardous location lighting or marine environment lighting equipment and the project layout. The supplied data does not provide mounting height, spacing, or coverage requirements.
How This Fixture Is Commonly Used
This junction box is incorporated into hazardous location lighting and explosion proof lighting layouts where a wall or ceiling connection point is needed. It is also used within marine environment lighting installations requiring the listed wet-location and marine classifications.
Placement follows the lighting layout, connected equipment location, and available conduit path. Higher mounting locations can affect motion sensor coverage, but sensor coverage dimensions are not established by the supplied data.
