Officially known as , this release represents a pivotal moment in lighting design history. Released in the early 2010s, it was the final major update of the "classic" DIALux interface before the radical shift to DIALux evo. While DIALux evo is now the manufacturer-supported standard, tens of thousands of lighting professionals continue to use DIALux 43 daily.

DIALux 4.13 offers a robust set of tools optimized for standard lighting calculation workflows.

4 GB minimum; 8–16 GB recommended for complex projects. dialux 43

Assign textures and reflection factors to walls and floors. If you leave them at default grey, your results might be lower than in reality because of low light bounce. 5. Running the Calculation

It integrates with manufacturer plug-ins, enabling the use of real luminaire data for precise calculations.

Building-based architecture. You design entire multi-story buildings, facades, and surroundings in one file. CAD Engine Click the calculation icon to run the simulation

Always set your maintenance factor (e.g., 0.80 for clean environments) to account for aging and dust. 3. Adding Luminaires (The "Plug-ins")

While DIALux 4.1 was already mature, version 4.3 introduced several important updates that refined the user experience and expanded the software's capabilities:

Available in 27 languages and used by millions of designers. While DIALux evo is now the manufacturer-supported standard,

Unlike Evo’s "working plane," Dialux 4.3 uses explicit calculation surfaces. You draw a grid on the floor, wall, or ceiling, and the software calculates the lux at every intersection. This is essential for sports lighting (vertical illuminance) and emergency lighting (0.5 lux lines).

DIALux 4.13 is a free, comprehensive planning tool used to design, calculate, and visualize lighting for indoor and outdoor spaces. It allows users to simulate lighting scenarios to optimize for visual comfort, energy efficiency, and compliance with international safety regulations.
