What does the software offer?

Using the ReluxCAD for Revit add-on, the required number of luminaires in interior spaces can be determined in line with standards. Electrical designers are thus equipped with an easy-to-use and comprehensible simulation tool in their familiar working environment.

A native interface to the ReluxDesktop application enables loss-free communication with lighting designers.

As an electrical designer, you are responsible for ensuring that the positioning of luminaires in buildings complies with standards. On average, only 10% of installed luminaires are checked for compliance with lighting standards at present.

Enhance the planning quality of lighting in buildings! This tool allows you to do just that.

Customer feedback
We are currently evaluating ReluxCAD for Revit for lighting calculation in Revit and are impressed with its features! One major advantage is the extensive database of luminaire families, which can be supplemented with our own families.


ReluxCAD for Revit improves the workflow for lighting design using Revit. A great tool for both lighting designers and electrical engineers.

Book a free product presentation

Exclusively for new customers and those interested in lighting design in Revit: Learn in a free 20-minute online presentation how you can make lighting design work processes even more efficient with the help of the ReluxCAD for Revit add-on. Available in German, English or Italian.

Reach your goal, in two steps.
1. Select luminaires and sensors

The add-on imports rfa or ies files and automatically adapts them to the particular Revit version.

Using neutral products in your planning? No problem! Import them and don't forget to include the light distribution curve.

2. Assign, calculate and display usage profiles and luminaires

Inform the Room Manager of the main activities carried out in the rooms, then obtain the requirements with regard to standards. 
Select the desired luminaire type for the basic lighting.

When the lighting simulation begins, the lighting in each room in the building is calculated correctly and luminaires are positioned automatically.

A usage list is created to clarify which luminaires are to be installed where.
The lighting simulation can be displayed in 2D or 3D.

Practical Features

Bidirectional interface - Communication with lighting designers

A bidirectional interface enables loss-free communication with the ReluxDesktop lighting design programme.

ReluxDesktop was developed for lighting designers and fulfils all the needs of those working in this field in a professional capacity.


Further developments in emergency lighting will be continuously added in 2023 and 2024.
