Dialux Evo 9 Direct

The integrated raytracer allows users to generate photo-realistic images of their lighting concepts, complete with accurate textures, reflections, and material properties.

DIALux evo 9 is the result of years of dedicated development by DIAL GmbH, a company that has been at the forefront of lighting design software since 1989. The software is a complete redesign of the classic DIALux 4.xx, moving away from a purely technical calculation tool to a more intuitive, building-oriented platform. As its developer states, DIALux evo is the successor to DIALux 4, and with the release of version 8.2, it already included most of the predecessor's core functions.

DIALux evo 9 is a free, professional-grade software suite used for calculating, simulating, and visualizing architectural lighting. Unlike basic calculation tools, DIALux evo 9 allows users to design lighting systems for entire buildings, individual rooms, outdoor spaces, and complex road networks within a single project file. It utilizes real photometric data provided directly by global luminaire manufacturers, ensuring that virtual simulations match real-world performance. Key Features and Innovations in Version 9

Another key advantage is its massive database. DIALux evo comes with direct access to over 2.5 million luminaires from more than 400 well-known manufacturers, all of which are DIALux Members. This ensures that calculations are based on real photometric data, making results accurate and reliable.

The software is not just about numbers; it creates high-quality visualizations to help communicate designs to clients. You can generate isolines, value charts, and false-color renderings to evaluate results and produce compelling project documentation. The "show light visualisation" tool allows you to view the light output of a single luminaire without calculating the whole project, which is particularly useful for focusing adjustable lights.

DIALux evo performs calculations in accordance with international standards. For indoor lighting, you can evaluate spaces based on standards like EN 12464. For street lighting, the software defaults to EN 13201:2015, a standard that can be easily changed to suit local regulations. The powerful Results Monitor provides a clear overview of key metrics, using a traffic light system (red/green) to immediately show whether a calculation surface meets its target value. As its developer states, DIALux evo is the

One of the most visible changes in evo 9 is the completely redesigned project documentation. The new layout features a larger, more professional typeface and more visually appealing images. Beyond aesthetics, the documentation is now more functional. You can now generate a complete room overview that lists every space with its respective luminaires and energy data in a single report, eliminating the need to create outputs for each individual room. The PDF export has also been improved, ensuring file sizes are no longer as heavy as before.

DIALux evo 9 allows engineers to check compliance with local and international lighting standards (e.g., EN 12464-1 for interior workplaces). It provides detailed reports on total luminous flux, load, and light output ratio. 4. Workflow in DIALux evo 9
