While DIALux 4.3 is highly capable, the industry has largely moved to DIALux evo. The newer platform allows for entire building designs rather than individual room-by-room calculations. However, for those focusing on individual luminaire performance and rapid "workhorse" calculations, version 4.3 remains a respected name in the field.

DIALux 4.13 is a comprehensive, free software tool used for calculating and visualizing indoor, outdoor, and street lighting. Developed by DIAL, this classic version provides a robust calculation engine that complies with international standards, such as EN 12464-1 for indoor workplaces and EN 13201 for street lighting. Unlike DIALux evo, which focuses on entire buildings and architectural spaces, DIALux 4.13 operates on a project-by-project, room-by-room basis, making it exceptionally fast for straightforward engineering tasks.
