While DIALux evo 14.0 is the current, supported version for new projects, you can still find legacy 4.x versions online through manufacturer websites or archival sites. Download and install DIALux 4.3.
DIALux 4.13 is a precise, desktop-based lighting simulation environment that allows electrical engineering professionals to input spatial dimensions, choose real-world manufacturer fixtures, and generate detailed photometric reports. Unlike modern counterparts that process entire smart buildings at once, DIALux 4 operates primarily on a . The Split User Experience
The interface is split into three main areas: the (left), the CAD Window (center), and the Inspector (bottom left). dialux 43
Run the calculation (daylight and artificial light).
, enabling engineers, architects, and lighting planners to simulate, calculate, and visualise light for indoor and outdoor spaces. Within the history of this powerful ecosystem, the transition from the legacy DIALux 4 architecture (which culminated in versions like 4.12 and 4.13) to the modern DIALux evo platform represents the single biggest technological leap in the lighting industry. While DIALux evo 14
: Use the "Automatic Arrangement" tool to meet a target illuminance (e.g., 500 lux for offices) or place luminaires manually for aesthetic effect.
This article explores the features, workflow, and enduring relevance of , comparing it with modern alternatives to understand its place in the 2026 lighting industry. What is DIALux 4.13? , enabling engineers, architects, and lighting planners to
OpenGL 3.2 support is required; 2 GB+ dedicated memory is recommended.
Users can easily define work planes, calculation grids, and specific calculation surfaces within a room.
The software allows users to analyze the power efficiency of their designs to meet modern green building standards.
: For straightforward indoor or outdoor calculations, the streamlined interface can sometimes feel faster than the more complex evo platform.
