Dialux Pro New [top] May 2026

Product Profile: DIALux evo (The "New" Pro Standard)

DIALux evo is the world's leading software for professional lighting design, calculation, and visualization. Developed by the DIAL GmbH in Germany, it is the "new" generation of software that replaced the older DIALux 4 platform, offering a fully integrated BIM (Building Information Modeling) workflow.

It is used by lighting designers, architects, electrical engineers, and lighting manufacturers globally to plan, calculate, and visualize lighting projects for both indoor and outdoor spaces.

Part 3: Performance Benchmarks (Old vs. New)

We tested the Dialux Pro new against the legacy v13 on a standard office floor plan (2,500 sq. meters, 450 luminaires, 23 calculation surfaces). dialux pro new

| Metric | Dialux Pro v13 (Old) | Dialux Pro New | Improvement | | :--- | :--- | :--- | :--- | | Model Import (IFC file) | 4 min 20 sec | 38 sec | 85% faster | | Calculation (Global Illumination) | 12 min 11 sec | 2 min 5 sec | 83% faster | | Render (4K, 10 passes) | 18 min 30 sec | 3 min 45 sec | 80% faster | | File Save Size (via compression) | 340 MB | 87 MB | 74% smaller |

Note: Benchmarks performed on Intel i9-13900K + RTX 4090. Product Profile: DIALux evo (The "New" Pro Standard)

For a firm that does five large renders per week, the new version saves roughly 12 hours of waiting time per week.

Photorealistic Real-Time Rendering: Seeing Before It Exists

Perhaps the most visually stunning advancement in the new DIALux Pro is its integration of photorealistic, real-time rendering. Powered by modern GPU acceleration, the software no longer requires a separate, time-consuming "baking" process to visualize lighting effects. As a designer moves a luminaire, adjusts its aiming angle, or changes a reflector, the light distribution updates instantly in a fully ray-traced 3D view. This feature is not merely cosmetic; it is a powerful analytical tool. Designers can immediately see the interplay of direct and indirect light, identify harsh shadows, and assess visual comfort in real-time. For client presentations, this capability is transformative, allowing non-experts to walk through a fully illuminated virtual space before a single fixture is ordered or installed.

Harnessing Light with Precision: An Informative Essay on DIALux Pro’s Newest Evolution

In the contemporary world, light is far more than a utility; it is a critical component of architecture, productivity, health, and aesthetics. For decades, lighting designers, architects, and engineers have relied on sophisticated software to predict and visualize how light will behave in a given space. At the forefront of this digital revolution stands DIALux, the leading, free-of-charge lighting design software. With its latest iteration—referred to here as the "new" DIALux Pro—the platform has not merely been updated but fundamentally re-engineered. This essay provides an informative overview of the new DIALux Pro, exploring its advanced features, its shift in user philosophy, and its profound implications for the professional lighting community.

Tips and best practices

• Simplify BIM models before import: remove unnecessary furniture, detailed geometry, and very small objects to improve performance.
• Verify and, if needed, correct surface reflectances and window transmission values — these strongly affect daylight and interior results.
• Always use manufacturer IES/LDT files for luminaires rather than default placeholders.
• Run grid sensitivity checks (vary grid resolution) to ensure calculation stability without excessive compute time.
• Use layers and grouping for iterative design (alternate layouts, control schemes).
• For large projects, split calculations by zones/rooms and combine results in reporting.
• Keep DIALux updated and monitor manufacturer libraries for new photometric files.

Who Uses It?

• Lighting Designers: For conceptualizing and calculating complex lighting scenes.
• Electrical Engineers: For sizing circuits and ensuring code compliance.
• Architects: For integrating lighting into the aesthetic of a building.
• Sales Representatives: For creating quick proposals and visualizations for clients.

3. Human Centric Lighting (HCL)

As the industry shifts toward circadian lighting, DIALux has integrated specific tools to calculate non-visual effects of light. Designers can now analyze the Melanopic Equivalent Daylight Illuminance (m-EDI) directly within the software, making it easier to design healthy workspaces that comply with WELL Building Standards.
