Represented a complete paradigm shift. Unlike the room-by-room approach of Dialux 3.14, Dialux evo allows designers to model entire buildings, multiple stories, and outdoor spaces simultaneously. It utilizes modern CAD imports (.dwg) and integrates directly into BIM workflows via IFC files.
Furthermore, for teaching basic photometry at a university level, 3.14 is superior. Students learn why the inverse square law matters, rather than just dragging a light meter in a 3D game engine.
Installation of DIALux 3.14 would have been a straightforward, menu-driven process. As with all versions of DIALux, the software itself was completely free. Dialux 3.14
The power of Dialux 3.14 lies in its .ldt (Luminaire Data) and .ies (Illuminating Engineering Society) file support. You can drag and drop any manufacturer’s photometric file directly into the library. Unlike evo, 3.14 does not "phone home" for updates, making it reliable for offline work.
The table below highlights the stark contrast between the classic 3.14 era and contemporary lighting design software: Dialux 3.14 Era Modern Dialux evo Room-by-room isolation Entire building and site holistic design CAD Integration Basic 2D DXF background Dynamic 2D/3D DWG and BIM (IFC) import/export Ray Tracing Flat shading, basic visualization Photo-realistic visualization with global illumination Standards Legacy EN and IES standards Constantly updated global norms (EN 12464-1, etc.) LED Optimization Designed for HID, Fluorescent, Halogen Specialized for tunable white, RGBW, and LED matrices Conclusion Represented a complete paradigm shift
Instead of building walls in DIALux:
The core workflow in DIALux 3.14 was efficient, allowing designers to move from concept to a detailed plan, as demonstrated in the 2022 academic study: Furthermore, for teaching basic photometry at a university
If you are looking for current lighting design tools, the following options are recommended: DIALux evo
Before the modern, high-powered DIALux evo 13 took over, t14 . For many veteran engineers, this wasn't just software; it was the reliable workhorse that designed the first energy-efficient offices and complex city streetscapes of the new millennium. Version history - Knowledge Base DIALux evo
