Understanding the business needs of professionals, DIALux Pro employs a flexible subscription model rather than a traditional upfront license purchase. Monthly subscriptions range from €19.99 to €29.99 depending on the user's geographic region, while annual subscriptions range from €219.99 to €329.99 per year.
An airport terminal has a 20-meter-high ceiling, glass curtain walls, and reflective flooring. is required to calculate the interreflected light from the floor back up to the ceiling. It also models emergency lighting egress paths, ensuring 1-lux minimum on the floor under battery backup conditions—a life safety requirement.
A unique strength of DIALux Pro is its sophisticated daylight calculation engine. It can simulate the impact of windows, skylights, and shading devices, analyzing how natural light contributes to the overall illumination throughout the day and across seasons. This functionality is critical for designing sustainable buildings that maximize energy savings and enhance occupant well-being through dynamic, biologically effective lighting.
: You can automatically generate PowerPoint presentations from your project results. The software includes a 16:9 template that creates slides based on your calculated results, which can then be further edited in Microsoft PowerPoint.
The DIALux Community serves as a central hub for users to connect, share knowledge, and receive support. Active forums allow professionals to discuss technical issues, share best practices, and provide feedback that directly influences software development. "We aim to involve you, our community, even more deeply in this process and look forward to your active participation," DIALux representatives note. dialux pro
Here is a comprehensive breakdown of what DIALux Pro is, its core features, and how it can elevate your professional lighting design practice. What is DIALux Pro?
Professional presentation is crucial in winning client confidence. DIALux Pro provides a layout editor that allows users to create documentation templates incorporating corporate design elements and personal style preferences. This personalized approach to reporting helps designers stand out in a competitive market.
Green building certifications require documentation. The Pro version calculates for the entire building. It automatically compares your design against legal maximums (e.g., Energy Performance of Buildings Directive in the EU), producing the exact tables needed for LEED EQ credit 7.1.
Introduced with DIALux evo 12, DIALux Pro represents a significant milestone. "This enhanced version, particularly in the area of data interfaces, allows for a significant increase in productivity and efficiency. It simplifies the import of data into DIALux for planning and the export of planning results for use in other software or processes," the DIALux team explains. This approach fundamentally changes how lighting designers can work across different platforms and collaborate with other disciplines. is required to calculate the interreflected light from
: Users can create personalized report layouts and export results to professional formats like PowerPoint, Excel, and Word for polished client presentations.
The software’s foundation is its ability to perform physically correct lighting calculations based on the photometric data (IES or LDT files) of real luminaires. It calculates key metrics mandated by international standards like CEN, ANSI/IESNA, and CIE, including average illuminance (lux), uniformity (U0, U1), glare rating (UGR), and daylight factor. This ensures that a design will meet legal and practical requirements before a single fixture is installed.
DIALux Pro is the unsung hero of the built environment. It is the tool that ensures a factory worker can see a safety hazard, a footballer can see the ball on TV, and a driver doesn't get blinded by glare on the highway.
DIALux Pro is designed to be accessible for a range of users and project needs: It can simulate the impact of windows, skylights,
: Designers load full 3D building models straight from CAD systems like Revit, ArchiCAD, or Vectorworks. Rooms, structural dimensions, and spatial barriers are automatically generated within the workspace.
One of the most significant developments in the DIALux Pro ecosystem is the upcoming Revit Add-In. Traditional workflows involving Revit have presented challenges for lighting designers, as exporting from Revit and reimporting files often resulted in lost information. "These partially poor open interfaces might even be intended to keep the planner inside the Revit ecosystem—hence, closed BIM," explains Dieter Polle. However, this is changing.
: By automating the documentation process, DIALux Pro eliminates the need for manual data copying between the software and external reports.
