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 hook adapter provides a 3/4 inch NPT connection for compatible Explosion Proof EXPLA and EXPLB fixtures. It is a mounting accessory, not a light-producing fixture.
The adapter supports hazardous location lighting configurations where the fixture installation requires a hook-style connection. Its 5.6 x 5.6 x 4.2 inch body should be accounted for when checking clearance around the fixture.
Core Performance and Output
This adapter has no wattage, lumen output, beam distribution, or electrical operating function. Its role is to provide the specified mechanical connection for compatible fixtures.
The 3/4 inch NPT connection must match the fixture and mounting assembly. Fixture output, optical distribution, and electrical performance remain dependent on the attached EXPLA or EXPLB fixture.
Adjustability and Control Options
No aiming, dimming, sensing, or control functions are provided by this hook adapter. Control capability is determined by the compatible fixture and its installed electrical components.
The adapter is intended for a fixed mounting connection. Confirm the fixture orientation and suspension arrangement before final installation.
Longevity and Reliability
The adapter has durable construction for long-term use with compatible explosion proof fixtures. It carries a 5-year warranty.
Periodic inspection should confirm that the threaded connection remains secure and that the adapter has not been damaged during fixture service or replacement.
Build Quality and Physical Characteristics
The adapter measures 5.6 x 5.6 x 4.2 inches. Its compact body fits within explosion proof fixture mounting assemblies designed for a 3/4 inch NPT connection.
This accessory is designed for Explosion Proof EXPLA and EXPLB fixtures. Verify fixture compatibility before installation.
Where This Product Fits Best
This adapter fits compatible EXPLA and EXPLB fixture installations in classified hazardous locations and related controlled environments.
- hazardous location lighting
- explosion proof lighting
- paint booth lighting
- chemical processing facility lighting
- oil and gas facility lighting
- solvent storage area lighting
Its UL844 hazardous location listing includes Class 1 Division 2 Groups A, B, C, and D, plus Class 2 Division 1 Groups E, F, and G.
Installation and Long-Term Use
Install the adapter only with compatible Explosion Proof EXPLA or EXPLB fixtures and a matching 3/4 inch NPT mounting connection. The threaded connection should be fully engaged and secured as part of the fixture installation.
Allow clearance for the adapter dimensions and for future fixture servicing. Installation work should maintain the classified-location requirements of the completed lighting assembly.
How This Fixture Is Commonly Used
This adapter is used as part of suspended compatible fixture assemblies for hazardous location lighting, paint booth lighting, and chemical processing facility lighting. Mounting height is determined by the fixture layout and project requirements; no mounting-height range is established for the adapter.
Fixture spacing and layout are based on the attached fixture output and photometric plan. The adapter changes the mounting connection, not fixture coverage or light distribution.
