: If you encounter issues, such as decimal numbers displaying incorrectly on Windows 11, the DIALux Community
The transition from DIALux 4.13 to DIALux evo marked a shift from room-based design to whole-building modeling. While DIALux 4.13 is limited to calculating single, enclosed rooms where wall openings are treated primarily as graphical elements, evo allows for integrated building structures and complex BIM (Building Information Modeling) workflows. DIALux Community
: Newer models like the Dialux 20 and Dialux 22 migrated to a 42mm dovetail , making heads between these generations non-interchangeable without significant modification. dialux 43
Quickly configure and switch between multiple dimming and color scenarios.
For projects not requiring complex 3D rendering of an entire building, the simplicity of 4.3 is a benefit. It requires fewer computational resources than Evo, making it ideal for older workstations. 4. Familiarity and Workflow : If you encounter issues, such as decimal
In the fast-paced world of lighting design, software tools evolve rapidly. Yet, even with the rise of modern, building-focused, 3D-heavy software like DIALux evo, the legacy ���and specifically its refined versions such as DIALux 4.3 ���remains a staple in the toolkit of many lighting designers, electrical engineers, and architects.
DIALux is a free, professional-grade software used to calculate and visualize lighting for indoor and outdoor spaces. It is developed by , a German lighting technology company. Quickly configure and switch between multiple dimming and
You must manually download manufacturer plugins (Philips, OSRAM, Trilux). In 2025, many manufacturers have removed 4.3 plugins. You need to use the "Import IES" function instead.
): This is the ratio of minimum illuminance to average illuminance. High uniformity ensures that light is distributed evenly across a floor or work surface without creating distracting bright spots or dark shadows.
: It is designed to perform accurate lighting calculations, ensuring that designs meet required standards for illumination and uniformity. Professional and Educational Use
For streets, Dialux 4.3 includes a "Street" wizard. You define the road width, pole spacing, mounting height, and overhang. The software calculates the luminance (cd/m族) and uniformity (U0) according to CIE 140 or EN 13201 standards.
