LEDVANCE supports DIALux and RELUX - the world-wide leading software applications for professional light planning. Find the latest information and software downloads here.

DIALux offers the possibility to specify the light source inside a luminaire, in order to meet the requirements of your lighting projects.

To install the plug-in on your computer, please download the .zip file, unpack it and start the enclosed .exe file.

The DIALux plug-in provides an update function: By clicking the button “Update“, the program will search for new product data and automatically update your database.

DIAL has developed DIALux, the world's leading software for planning, calculating and visualizing indoor and outdoor lighting. The light-planning tool has a community of more than 700,000 users and is available in 25 languages. All major luminaire manufacturers offer digital product data for planning purposes in DIALux. The software makes professional lighting design easier and accessible to everyone. As a platform and tool, it connects planners and manufacturers all over the world.

All LEDVANCE luminaire products are also available in LUMsearch , another DIAL tool for professionals. LUMsearch helps designers and planners to search for and select products, the idea being that leafing through paper catalogues and visiting countless websites are now obsolete activities. The products are described in detail and users can immediately include products by DIALux partners such as LEDVANCE in the DIALux planning tool and make contact with their producers.
