DIALux Pro is the premium subscription tier of DIALux evo, designed to unlock advanced workflow automation, customized reporting, and professional-grade features for lighting designers and engineers. While the standard version of DIALux remains free for basic planning, the Pro version is built for those who need to deliver high-stakes projects with maximum efficiency and a polished, branded output. The Evolution of Professional Lighting Design
For decades, DIALux has been the industry standard for calculating illuminance, uniformity, and energy efficiency. However, modern lighting design requires more than just raw data; it demands seamless integration with other architectural tools and the ability to present complex information in an understandable format for clients. DIALux Pro addresses these needs by bridging the gap between technical calculation and professional presentation. Core Features of DIALux Pro
The Pro version introduces several critical enhancements that differentiate it from the standard software:
Customized Reporting and Branding: Users can create bespoke report templates, allowing them to include company logos, specific layouts, and customized data visualizations. This is essential for firms that need to maintain a consistent brand identity in their technical documentation.
Export to Microsoft Excel: While the standard version excels at generating PDFs, DIALux Pro allows for the direct export of luminaire lists and calculation results into Excel. This facilitates easier budget management and integration into broader project management spreadsheets.
Advanced IFC and BIM Integration: Building Information Modeling (BIM) is now central to modern construction. DIALux Pro offers enhanced capabilities for importing IFC (Industry Foundation Classes) files, ensuring that architectural data from software like Revit is preserved accurately—including levels, room names, and material properties.
Unlocked Non-Member Luminaire Data: DIALux is funded by its member luminaire manufacturers. In the standard version, using data from non-member manufacturers may come with restrictions or prompts. DIALux Pro removes these barriers, offering total flexibility in choosing fixtures from any source without interruption. Workflow Efficiency: From Revit to Calculation dialux pro
A major selling point for DIALux Pro is its ability to handle complex architectural models. For instance, designers can export specific views from Revit (typically using the IFC 2x3 format) and import them directly into DIALux. This process preserves:
Spatial Definitions: Rooms and 3D spaces are recognized instantly.
Geometric Accuracy: Malls, columns, and ducts are organized by level, preventing the need to redraw the building from scratch.
Verification: Once imported, designers can quickly apply "utilization profiles"—such as gymnasiums or offices—to verify if the lighting meets required standards like 0.4 uniformity. Economic and Professional Impact
Moving to a subscription-based "Pro" model allows the software to stay at the cutting edge of energy-efficient and low-carbon architectural design. Accurate simulations help designers optimize energy consumption, which is critical given that over 80% of the world's energy still comes from fossil fuels. By using precise calculation tools, designers can ensure they aren't over-lighting a space, thereby reducing carbon emissions and operational costs for clients. Is DIALux Pro Right for You?
DIALux Pro is an investment in professional productivity. It is best suited for: DIALux Pro is the premium subscription tier of
Large Engineering Firms: Who require standardized, branded reports for multi-million dollar tenders.
BIM Managers: Who need to ensure seamless data flow between Revit and lighting simulations.
Independent Consultants: Who want the freedom to use any luminaire manufacturer without technical hurdles. Dialux Evo's user-friendly interface makes it simple for
Standard evo struggles with complex DWG imports. DIALux Pro acts like a hybrid between AutoCAD and a calculator.
Standard software simulates general illumination. Dialux Pro includes dedicated emergency lighting design. You can place self-contained or central battery system luminaires and simulate the maintained illuminance (typically 1 Lux or 0.5 Lux on the escape route). The software automatically marks "shadow zones" where the emergency light fails to reach, saving you from costly installation errors.
Let’s look at three scenarios where the "Pro" label is mandatory. Standard evo struggles with complex DWG imports
If you are a student or a small electrician doing residential work, the free Dialux evo is more than sufficient. It is a world-class tool for zero cost.
However, if you are an MEP (Mechanical, Electrical, Plumbing) engineering firm, a lighting design consultancy, or a commercial electrical contractor bidding on stadiums, hospitals, and highways—Dialux Pro is non-negotiable.
The cost of the license is offset by the first project alone. By eliminating re-purchases (export limits) and ensuring compliance (avoiding fines for bad lighting), Dialux Pro doesn't just design light—it manages risk.

❌ Wrong photometric file – Always verify the .ldt or .ies file matches the exact luminaire model.
❌ No workplane defined – Without a calculation surface (e.g., floor at 0.8m height), results are meaningless.
❌ Ignoring maintenance factor – Set MF (0.8 for clean offices, 0.67 for industrial) to simulate dirt/lumen depreciation.
❌ UGR not calculated – In offices, always enable UGR to avoid complaints about glare.
❌ Exporting raw screenshots – Use the report generator – it's faster and professional.
