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 wall mount arm bracket supports wall-mounted EXPLA and EXPLB explosion proof fixtures. It is intended for hazardous location lighting installations where the fixture requires a wall arm mounting arrangement.
The bracket measures 5.6 x 5.6 x 4.2 inches. Its hazardous-location classifications align with installations requiring Class I Division 2 or Class II Division 1 equipment.
Core Performance and Output
This is a fixture mounting component and does not produce light output. Its function is to provide a wall mount arm configuration for compatible EXPLA and EXPLB fixtures.
Bracket placement must account for the fixture dimensions, wall structure, aiming requirements, and available clearance. The supplied data does not establish fixture weight capacity, EPA rating, or wind-load performance.
Adjustability and Control Options
No fixture controls, dimming functions, or electrical components are included with this wall mount arm bracket. Controls are determined by the compatible EXPLA or EXPLB fixture configuration.
The supplied product data does not identify an adjustable arm, swivel, or aiming mechanism. Final fixture direction depends on the installed fixture and wall mounting position.
Longevity and Reliability
The bracket is classified for UL 844 hazardous location use. It is intended for installations using compatible EXPLA and EXPLB fixtures.
Long-term performance depends on correct wall mounting, fixture compatibility, and maintaining the installation within the listed hazardous-location classification. Material construction and environmental exposure limits are not stated in the supplied data.
Build Quality and Physical Characteristics
The bracket has overall dimensions of 5.6 x 5.6 x 4.2 inches. Its compact size should be checked against available wall surface, conduit routing, fixture clearance, and required aiming position.
This bracket is designed for EXPLA and EXPLB explosion proof fixtures. No alternate fixture compatibility is identified in the supplied product information.
Where This Product Fits Best
This wall mount arm bracket fits hazardous-location lighting installations using compatible EXPLA or EXPLB fixtures. It applies where a wall-mounted fixture position is required within the listed classifications.
- hazardous location lighting
- explosion proof lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- refinery lighting
Installation conditions must remain consistent with the listed Class I Division 2 Groups E, F, and G and Class II Division 1 Groups A, B, C, and D classifications. The supplied data does not establish suitability for applications outside these classifications.
Installation and Long-Term Use
The bracket mounts compatible EXPLA and EXPLB fixtures to a wall-mounted arm position. Confirm wall structure, mounting location, fixture clearance, and the required fixture orientation before installation.
Mounting height is determined by the lighting layout and fixture placement requirements for the project. The supplied data does not provide a mounting-height range, hardware list, or structural loading value.
How This Fixture Is Commonly Used
This bracket is used where hazardous location lighting requires an EXPLA or EXPLB fixture to be positioned from a wall. Wall placement is coordinated with the intended fixture direction and the available mounting surface.
Fixture layout depends on mounting height, target light levels, and the arrangement of the hazardous location lighting area. A wall-mounted position can affect fixture spacing and aiming compared with other mounting configurations.
