What does the software offer?

ReluxDesktop is a powerful and intuitive application for the simulation of artificial light and daylight


ReluxDesktop allows you to plan individual rooms, entire floors, industrial halls, or outdoor areas such as car parks, sports facilities, and roads – all in just one piece of software.

Calculate absolute values according to national and international standards, compatible with CAD and BIM systems. ReluxDesktop supports the import and export of different formats. You can also plan sensors using ReluxDesktop – the only software on the market that allows you to do so.
Planning emergency lighting is also particularly easy and precise.

Customer voices


I use ReluxDesktop as the #1 tool because the standard-compliant planning and mapping of daylight and artificial light are possible. I also greatly appreciate the innovative interfaces to different formats. This allows me to work on my projects much more efficiently and achieves a significantly higher order probability. I can recommend it without reservation.
