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 an enclosed connection point for hazardous location lighting and related electrical equipment. It has a 3/4 NPT configuration and measures 5.6 x 5.6 x 4.2 inches.
The enclosure is rated IP66 and is intended for installations requiring a sealed junction box in classified and wet location conditions. Its listed classifications cover Class I, Class II, and Class III locations.
Core Performance and Output
This junction box does not produce light output. Its performance is defined by its hazardous-location classifications, wet location suitability, and IP66 enclosure rating.
The enclosure is listed for Class I, Division 1, Groups C and D; Class I, Division 2, Groups A, B, C, and D; Class II, Division 1, Groups E, F, and G; Class II, Division 2, Groups F and G; and Class III locations.
Adjustability and Control Options
No lighting controls, dimming functions, or adjustable output features are identified for this junction box. It serves as a fixed electrical enclosure.
The 3/4 NPT configuration should match the connection requirements of the installed electrical system. Verify conduit and fitting requirements before installation.
Longevity and Reliability
The IP66 rating supports use where the enclosure requires protection from dust and powerful water jets. UL 1598 wet location suitability is listed.
This junction box includes a 5-year warranty. Long-term service access depends on the installed wiring method and connection layout.
Build Quality and Physical Characteristics
The enclosure measures 5.6 x 5.6 x 4.2 inches. Its compact square form factor provides a defined space for electrical connections.
The box is rated IP66 and uses a 3/4 NPT configuration. Confirm physical clearance around the enclosure before final placement.
Where This Product Fits Best
This junction box fits classified, wet, marine, and process-oriented installations where the listed hazardous-location classifications match the site conditions.
- hazardous location lighting
- explosion proof lighting
- chemical processing facility lighting
- paint booth lighting
- oil and gas facility lighting
- marine environment lighting
UL 844 hazardous location classification, UL 1598 wet location suitability, UL 1598A Marine Outside Type listing, ABS certification, and IP66 protection define its environmental fit.
Installation and Long-Term Use
Install the junction box where its 3/4 NPT configuration and listed classifications match the electrical system and location requirements. The enclosure dimensions should be accounted for during layout and access planning.
Connection routing should leave adequate access for inspection and service. Final installation must maintain the enclosure’s intended environmental protection.
How This Fixture Is Commonly Used
This junction box is commonly incorporated into hazardous location lighting and explosion proof lighting installations as a protected connection enclosure. Placement follows the equipment layout and available access points.
Its compact dimensions support layouts where connection points must remain contained within a defined enclosure footprint. Junction box placement varies with conduit routing, equipment position, and service access requirements.
