Dialux 3.14 ((exclusive)) Jun 2026
For professional projects, documentation is key. DIALux 3.14 can automatically generate comprehensive, professional reports that include calculation results, luminaire placement plans, a detailed luminaire parts list, and a summary of all project data, which can be printed or exported for client presentations and compliance verification.
However, if you are designing a museum, a hospital with complex daylight integration, or a stadium with 20,000 luminaires, you must use DIALux evo (or Relux 2025). The modern calculation algorithms handle indirect light and daylight autonomy far better.
| Feature | DIALux 3.14 (Legacy Version) | DIALux evo (Modern Version) | | :--- | :--- | :--- | | | Primarily room-based design | Building Information Modeling (BIM)-based project design | | 3D Graphics | Basic 3D rendering | Advanced, physics-based graphics engine | | Calculations | Photorealistic lighting computations | Supports comprehensive daylight and emergency lighting calculations | | Import/Export | Standard CAD and image files (e.g., .dwg , .dxf , .jpg ) | Supports modern BIM formats and 3D scans | | Manufacturer Data | Separate plug-ins for each manufacturer | Integrated platform with data from DIALux Member manufacturers (limitations may apply to non-members) | | User Base | Grew to hundreds of thousands of users worldwide | Has over 700,000 professional users globally |
Before the modern online DIALux Luminaire Finder , version 3.14 pioneered electronic catalog integration. It gave planners the ability to import exact spatial and photometrical distributions from early manufacturing partners, laying the foundation for today's database of over 450 global members.

was the swan song of the original codebase. Version 4.0 (later renamed "evo") was already in development. DIALux 3.14 represents the peak of CAD-based, calculation-first design.
DIALux 3.14 set the stage for several features that remain essential in modern lighting design:
Dialux 3.14 utilized the for indirect light. This algorithm divides surfaces into small patches and calculates light bouncing between them. Version 3.14 had a specific optimization for "standard solve" iterations that prevented the "dark corners" bug found in version 3.11. For professional projects, documentation is key
Using Dialux 3.14 in a modern professional environment introduces significant challenges:
The lighting design world has moved on significantly since the days of DIALux 3.14. The most important change is the introduction of the current software line, , which was announced as the successor and released for use in 2012. Here are the key differences:
Even in version 3.14, DIAL provided specialized modules. The street lighting assistant calculates luminance ( ) and longitudinal uniformity ( UIcap U cap I The modern calculation algorithms handle indirect light and

Dialux 3.14 runs perfectly on a $50 refurbished office PC with Windows 7 or even Windows 10 (with compatibility mode). It requires no dedicated GPU. For small firms in developing nations, this is a lifeline.
