Dialux 43 ((new)) Jun 2026

Often referred to colloquially by older iterations, DIALux 4.x represents a matured, stable, and incredibly efficient environment for indoor and outdoor lighting calculations. Whether you are working on a simple office layout, a complex street lighting project, or specialized industrial lighting, DIALux 4.13 offers a tailored workflow that many professionals still prefer.

DIALux 4.3 is a highly reliable "classic" version best suited for users with old projects or those needing to perform rapid single-room calculations. However, for new projects, modern compliance, and improved workflow, DIALux evo is the current, fully-supported industry standard. DIALux Community Differences between Dialux Evo versions - Facebook

In 4.3, the user didn't model a "building" in the architectural sense. They modeled "rooms" or "exterior scenes." This modular approach was incredibly fast. dialux 43
