Indestructible, perfectly functional for its era, but obsolete for modern workflows. If your job requires a legally defensible lux contour map for a warehouse built in 2013, use 3.14. For anything else, move to DIALux evo 12+ (or Relux 2024).
: To run the latest iterations (DIALux evo), you typically need a 64-bit Windows OS, at least 4 GB of RAM (8-16 GB recommended), and a graphics card supporting OpenGL 3.2. Lighting design made easy with DIALux evo Dialux 3.14
This keeps 90% of your work intact.
| Feature | Dialux 3.14 | DIALux evo (modern) | | :--- | :--- | :--- | | | Low to Medium. Feels like CAD software. | Steep. Scene-based logic is confusing for CAD natives. | | Geometry Creation | Basic but precise (boxes, cylinders). | Powerful but glitchy with complex intersections. | | Calculation Speed | Fast for large regular rooms. | Slower for large scenes due to full volume calculation. | | Single Luminaire Placement | Easy. Click and copy. | Over-engineered (requires "furnishing" logic). | | Report Generation | Simple HTML/Excel tables. | Beautiful photorealistic PDFs. | | BIM Integration | None (pre-BIM era). | Full IFC import/export. | | Stability | Rock solid. Crashes were rare. | Depends on GPU drivers. Demanding. | : To run the latest iterations (DIALux evo),
Dialux 3.14 was the last of the "classic" interface designs. It featured a traditional menu bar, toolbars, and a calculation engine that was deterministic and transparent. Unlike the modern evo version (which uses a physically correct but sometimes unpredictable global illumination model), 3.14 used a slower but highly predictable radiosity and photon mapping hybrid.
