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 arm bracket includes a junction box and a fixed 25 degree mounting angle for compatible EXPLA, EXPLB, EXPLC, EXPLD, and EXPLG fixtures. It provides a compact mounting and wiring point for explosion proof lighting assemblies.
The bracket measures 5.6 x 5.6 x 4.2 inches. Its IP67 construction supports installations where the fixture mounting assembly requires protection from dust and water ingress.
Core Performance and Output
This arm bracket does not produce light or set fixture output. Fixture wattage, lumen output, beam distribution, and electrical performance are determined by the compatible explosion proof fixture.
The fixed 25 degree angle establishes the fixture aim at installation. Confirm the selected fixture orientation and lighting layout before mounting because the bracket does not provide field-adjustable aiming.
Adjustability and Control Options
The bracket has a fixed 25 degree mount angle. It does not provide adjustable tilt, rotation, dimming, sensor control, or driver control functions.
Control capability remains dependent on the compatible EXPLA, EXPLB, EXPLC, EXPLD, or EXPLG fixture and its supplied electrical configuration.
Longevity and Reliability
The IP67 rating applies to the bracket assembly. The durable construction is intended for long-term use with compatible explosion proof fixtures.
A 5-year warranty is included. Maintain the junction box and mounting assembly during fixture service to preserve the installed condition.
Build Quality and Physical Characteristics
The bracket integrates an arm mount and junction box in one assembly. This arrangement provides a defined mounting point and enclosed wiring location for compatible fixtures.
Overall dimensions are 5.6 x 5.6 x 4.2 inches. Confirm available mounting clearance and fixture dimensions before installation.
Where This Product Fits Best
This bracket fits explosion proof lighting assemblies used in classified lighting applications where a compatible EXPLA, EXPLB, EXPLC, EXPLD, or EXPLG fixture requires a 25 degree arm mount.
- hazardous location lighting
- paint booth lighting
- chemical processing facility lighting
- explosion proof lighting
- oil and gas facility lighting
- refinery lighting
The assembly carries an IP67 rating and UL844 Hazardous Location listing. Classifications include Class 1 Div 1 Groups A, B, C, D; Class 1 Div 2 Groups A, B, C, D; Class 2 Div 1 Groups E, F, G; and Class 2 Div 2 Groups F, G.
Installation and Long-Term Use
Install this bracket only with the compatible EXPLA, EXPLB, EXPLC, EXPLD, or EXPLG fixture series. The junction box should be accessible for wiring and future fixture service.
Verify mounting surface condition, fixture weight, wiring method, and required fixture orientation before installation. The supplied product data does not establish mounting hardware requirements or structural loading limits.
How This Fixture Is Commonly Used
The bracket is used to position compatible explosion proof fixtures at a fixed 25 degree angle in hazardous location lighting, paint booth lighting, chemical processing facility lighting, and refinery lighting layouts. Mounting height is determined by the compatible fixture and project lighting plan.
Fixture spacing and layout patterns remain dependent on the fixture output, optics, mounting height, and required light levels. The fixed angle can support directional fixture orientation, but it must be coordinated with the layout before installation.
