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 90 degree wall arm bracket with junction box provides a wall-mounted fixture position for compatible EXPLA, EXPLB, EXPLC, EXPLD, and EXPLG explosion proof fixtures. The bracket is intended for hazardous location lighting where a fixed right-angle wall mount is required.
The assembly includes a junction box and mounts fixtures at a 90 degree angle from the wall surface. Its compact 5.6 x 5.6 x 4.2 inch body suits wall locations where fixture placement, wiring access, and hazardous-location ratings must be maintained.
Core Performance and Output
This bracket does not produce light or establish fixture lumen output, wattage, beam distribution, or electrical performance. Those factors are determined by the compatible explosion proof fixture installed on the bracket.
The bracket provides a 90 degree wall mounting position. Fixture output and optical distribution should be reviewed against the mounting location because the bracket data does not establish coverage, spacing, or mounting-height limits.
Adjustability and Control Options
The bracket provides a fixed 90 degree wall arm position. No aiming adjustment, dimming function, sensor, or control function is identified for the bracket itself.
Controls and electrical operating characteristics depend on the compatible EXPLA, EXPLB, EXPLC, EXPLD, or EXPLG fixture. Confirm fixture controls and voltage requirements separately from the bracket selection.
Longevity and Reliability
The bracket is rated IP67. It carries a 5-year warranty.
The hazardous-location certifications apply to the bracket assembly as listed. Long-term performance also depends on correct wall attachment, junction box wiring, and use with the specified compatible fixture families.
Build Quality and Physical Characteristics
This is a wall-mount arm bracket with an integrated junction box. The 90 degree arm configuration holds the compatible fixture perpendicular to the wall mounting surface.
Overall dimensions are 5.6 x 5.6 x 4.2 inches. Verify available wall clearance, fixture dimensions, and wiring access before installation.
Where This Product Fits Best
This bracket fits hazardous-location wall-mount layouts requiring compatible explosion proof fixtures and a 90 degree mounting position. It is applicable where the listed hazardous-location classifications and IP67 rating align with the project requirements.
- hazardous location lighting
- explosion proof lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
UL844 hazardous-location classifications include Class I Division 1 and 2 Groups A, B, C, and D, plus Class II Division 1 Groups E, F, and G and Class II Division 2 Groups F and G.
Installation and Long-Term Use
Mount the bracket to a wall structure that supports the complete fixture assembly. The supplied product data does not establish wall fasteners, structural load limits, or fixture weight limits.
Use the integrated junction box for the fixture wiring arrangement. Confirm the compatible fixture model, wiring requirements, mounting height, and wall location before final installation.
How This Fixture Is Commonly Used
In hazardous location lighting, explosion proof lighting, paint booth lighting, chemical processing facility lighting, oil and gas facility lighting, and refinery lighting, the bracket positions a compatible fixture outward from a wall at 90 degrees. Mounting height is determined by the fixture output, optical distribution, and required light levels.
Wall-mounted layouts are arranged around the available mounting surfaces and required coverage pattern. Fixture spacing varies with the compatible fixture configuration and the lighting layout; no spacing values are established for this bracket.
