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. Key Features and Functionalities 3D Visualization and Simulation
Automatically calculates the number of fixtures needed to achieve a target lux level.
: Older Leitz Dialux models (such as the "Dialux II" or gray/black models) typically used a 43mm dovetail size for mounting heads (binocular, trinocular). dialux 43
Specialized tools to verify that emergency lighting levels comply with safety standards (e.g., EN 1838).
DIALux 4.3 is a highly reliable "classic" version best suited for users with old projects or those needing to perform rapid single-room calculations. However, for new projects, modern compliance, and improved workflow, DIALux evo is the current, fully-supported industry standard.

Do not rely blindly on the default 0.80 maintenance factor. Always adjust this value based on the specific light source (LED vs. legacy fluorescent), the IP rating of the fixture, and the dust levels of the room to prevent under-designing the system over its lifespan.

Define room dimensions, wall materials, and maintenance factors.
Use the LDC (Light Distribution Curve) preview to ensure you’re placing the light at the correct orientation. You can use the "Field Arrangement" tool to automatically distribute lights across a ceiling grid based on a target Lux level (e.g., 500 lx for an office). 4. Calculation and Objects
