Version 3.14 was the answer to every professional’s prayer: a tool that performed complex illuminance calculations (based on the radiosity method) almost instantly on the hardware of the late 2000s.
: It uses calculation methods based on outdated lighting standards that may not meet current regulatory requirements in many regions. Compatibility
In the luminaire selection wizard, you can filter by CCT (Correlated Color Temperature). Dialux 3.14
In version 3.14, plug-ins from global manufacturers (like Philips, Zumtobel, and Osram) were the primary way to load light fixtures. Users could manually import EULUMDAT (.ldt) and IESNA (.ies) photometric files to test custom fixtures. 3. Calculation Grids
Firms that designed major infrastructure projects in the late 1990s and early 2000s occasionally need to revisit archived project files. Keeping a copy or a reference of Dialux 3.14 ensures that old calculation files can be audited, verified, or updated accurately without file corruption during aggressive format conversions. The Transition: From Dialux 3.14 to Dialux evo Version 3
Did you know you can place a "Calculation Point" anywhere?
Released during a transitional period for the lighting industry, Dialux 3.14 represents the "golden mean" between the simplicity of earlier Illuminance calculation tools and the overwhelming complexity of modern Building Information Modeling (BIM). While DIALux evo has taken the torch forward, Dialux 3.14 remains a critical benchmark, a teaching tool, and in some niches, a production workhorse. In version 3
is not obsolete; it is a specialized tool. While a modern designer might look at its grey interface and shudder, the veteran engineer sees a scalpel—sharp, precise, and fast.
was the swan song of the original codebase. Version 4.0 (later renamed "evo") was already in development. DIALux 3.14 represents the peak of CAD-based, calculation-first design.
