It uses physically correct calculations based on IES or LDT files provided by real manufacturers. If you design a warehouse in DIALux Pro, the lux levels you calculate are the lux levels you will get on site—within a 5% margin of error.
The free version is now called . It continues to provide all the core functionality for creating indoor, outdoor, and street lighting designs, performing calculations according to international standards, and creating visualizations, all at no cost.
DIALux Pro does not alter the core calculation engine of DIALux evo; rather, it wraps that powerful engine in a suite of high-productivity tools. Here are the standout features that define the Pro experience: 1. Advanced Report Customization
The architecture, engineering, and construction (AEC) industry has increasingly adopted Building Information Modeling as the standard for project collaboration. DIALux Pro positions itself at the forefront of this movement with an explicit commitment to open BIM principles. "Lighting design meets BIM. Our goal is clear: to provide lighting designers around the world with a precise and stable foundation for their BIM projects," states Dieter Polle, CEO of DIAL GmbH. dialux pro
: 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
DIALux Pro bundles an impressive array of advanced functionality designed to accelerate workflows and enhance productivity. At its core, the package offers four primary capabilities that distinguish it from the standard free version.
When you activate the full suite, you unlock a dashboard of tools that turn a mere calculator into a design powerhouse. It uses physically correct calculations based on IES
). This data can be directly exported to external urban microclimate and energy simulation packages , accelerating green building approvals. 5. Step-by-Step: Setting Up a Pro BIM Workflow
: A Pro license is now required to use luminaires from manufacturers that are not official DIALux Members .
If your primary income relies on delivering rapid, high-end lighting layouts with corporate branding. It continues to provide all the core functionality
Designers can generate highly focused presentation packages. For example, you can choose to isolate and export only the illuminance levels, uniformity ratios, and energy consumption metrics required for local regulatory compliance (such as LEED, BREEAM, or EN 12464-1 code checks).
