For decades, the lighting industry has suffered from a "Darwinian split." On one side, electrical engineers use calculation software (like DIALux) to ensure compliance, energy efficiency, and uniformity. On the other side, lighting designers and artists use DMX consoles to create mood, dynamic scenes, and atmosphere. The two disciplines rarely speak the same language.
This paper introduces the DIALux 43, a hybrid hardware-software console designed to collapse these two worlds. The DIALux 43 is the first device capable of importing IES photometric data to calculate real-time lux levels while simultaneously outputting DMX/sACN signals for dynamic control. It is not just a controller; it is a lighting calculator that paints with physics.
Indoor offices suffer from glare. Dialux 4.3 contains a dedicated UGR module that calculates the psychological discomfort of lighting. You can place the observer at specific coordinates and run the UGR tabular method as defined by CIE 117-1995. dialux 43
After a decade of use, the DIALux 43 community has solved nearly every error. Here are the top five:
Error 1: "Could not load luminaire. The file is corrupt." For decades, the lighting industry has suffered from
Error 2: The calculation surface shows "NaN" (Not a Number).
Error 3: Crashes when opening a large DXF. Indoor offices suffer from glare
Error 4: Windows 11 compatibility – text looks tiny.
Error 5: The UGR table is empty.
DIALux 4.3 is a free, professional lighting design software developed by DIAL GmbH. It allows users to calculate lighting levels (illuminance, luminance, glare, UGR, etc.) based on real photometric data from nearly every major luminaire manufacturer (Philips, Osram, Zumtobel, Eaton, etc.).
