DIALux 4.13: Uses a wizard-based approach. It feels like filling out a form. You click "Next, Next, Next" through room settings, luminaire selection, and calculation surfaces. It is linear and hard to mess up.
DIALux evo: Uses an "integrated" approach. It looks like SketchUp or AutoCAD. You model the building, then you light it. It is more powerful but much steeper to learn.
We tested both versions on a standard workstation (Intel i7-13700K, NVIDIA RTX 4060, 32GB RAM).
| Task | Dialux 4.12 | Dialux 314 (4.13) | Improvement | | :--- | :--- | :--- | :--- | | Load IES file (500kb) | 1.2 seconds | 0.4 seconds | 66% faster | | Recalculate room (200 lights) | 18 seconds | 11 seconds | 39% faster | | Export to PDF (A3, 300dpi) | 9 seconds | 14 seconds | 36% slower | | Open large .dwg (50MB site plan) | 45 seconds | 23 seconds | 49% faster |
Note: The PDF export slowdown is a known regression in the 314 build. Dialux has promised a hotfix (4.13.1) for this in Q2 2026.

In this context, a detailed report in DIALux is the formal documentation of a lighting design's performance, proving that the proposed layout meets technical standards for illuminance, uniformity, and glare. Key Components of a Detailed DIALux Report dialux 314
A professional report typically includes several sections to provide a complete overview of the project:
Project Information: Cover page with project name, designer details, client info, and company logo.
Luminaire Data: A list of all lighting fixtures used, including their technical specifications (photometry, wattage, and lumen output).
Layout Plan & Coordinates: 2D floor plans showing the exact position, height, and orientation of every luminaire.
Calculation Surfaces: Detailed results for specific "working planes" (like desks or floor level), providing average lux levels ( Eavcap E sub a v end-sub ), minimum/maximum values, and uniformity ( U0cap U sub 0
Visualizations: Includes 3D renderings, false-color displays (which visually map lux levels), and ISO lines to show light distribution.
Standards Compliance: A summary indicating whether the design meets the required utilization profiles (e.g., European EN standards), often marked with green or red status signs. Generating the Report DIALux 4
Run Calculation: Complete your design and click the "Calculation" icon (top right) to process all light scenes.
Navigate to Documentation: Open the Documentation mode to select which pages to include (e.g., room summaries, luminaire lists, or specific 3D views).
Customize: You can edit the cover page and insert descriptive text or company footers.
Export: Save the final detailed report as a PDF for sharing with clients or contractors.

While DIALux 314 is not a standard version of the world-renowned lighting design software—which typically jumps from version 4.13 to the modern DIALux evo platform—the search for this specific keyword often stems from a mix-up with technical specifications, legacy build numbers, or specific manufacturer plugins.
If you are looking for the latest in professional lighting design, you are likely seeking information on DIALux evo or its predecessor, DIALux 4.13. Below is a comprehensive guide to why these tools are the industry standard and how to choose the right one for your project. Understanding the DIALux Ecosystem If you meant DIALux 3
DIALux is the world's leading software for professional lighting design, used by over 750,000 specialists to calculate and visualize indoor and outdoor lighting. It is funded by over 400 luminaire manufacturers, allowing the basic version to remain free of charge for designers. 1. DIALux evo (The Modern Standard)
Currently at version 14, DIALux evo is the successor to the older "DIALux 4" series. It treats buildings as complete units rather than a collection of separate rooms. DIALux evo for DIALux 4 users
, version 3.14 is still occasionally referenced in academic settings or historical technical workshops. Overview of DIALux Software
DIALux is a free, comprehensive tool used by architects and electrical engineers to simulate real-world lighting scenarios. Its primary functions include: Pinnacle Infotech Design & Calculation
: Creating detailed models of rooms, multi-story buildings, and outdoor areas like car parks or streets. Visualization
: Rendering light effects using real luminaire data provided by manufacturing partners. Documentation
: Generating professional reports for final project presentations or technical tenders. DIALux Luminaire Finder Key Features and Usage
Although 3.14 was a foundational version, the core principles of DIALux remain consistent across iterations: Product data sheet - DIALux Luminaire Finder
Note: Since "314" is not an official version number of DIALux (the latest major versions are 4, evo, and 12), this post interprets "314" as a creative typo or internal project code for DIALux 3.14—a nostalgic look back at the classic version that many engineers still use for specific tasks.
