This paper is for informational purposes. DIALux 4.3 is legacy software; users should verify compatibility with their local building codes and manufacturer data availability. Always upgrade to DIALux evo for professional liability and support.
| Feature | Description | Practical Benefit | |---------|-------------|--------------------| | | Automated placement of luminaires along roads with poles, overhangs, tilt. | Instant compliance with EN 13201. | | Calculation Zones | User-defined polygons, circles, or grids for isolated point calculations. | Ideal for task areas (e.g., a desk or a factory machine). | | Sports Lighting Module | Predefined court geometries (tennis, football) with camera positions. | Vertical illuminance calculations for TV broadcasting. | | Luminaire Exchange | Swap one luminaire type for another while keeping all positions. | Quick photometric comparisons. | | Export to CAD | Native .dwg and .dxf export with layers. | Seamless back-and-forth with AutoCAD. |
Optimized for calculating individual rooms and simple exterior spaces. Linaire Integration: dialux 4.3
Unlike EVO, you don't draw walls. You define a rectangular room by dimensions (Length, Width, Height). You define reflectance factors for ceiling, walls, and floor.
If you walk into an electrical engineering office in Europe or Asia, there is a high chance you will see Dialux 4.3 running on an old Windows 7 or Windows 10 machine. Here is why: This paper is for informational purposes
While 4.3 has an "Outdoor" mode, it is terrible by modern standards. You cannot model terrain, trees, or complex street topologies. For roads and floodlights, you need EVO or Relux.
: It offers a "Light" tool for rapid planning of standard projects alongside a comprehensive suite for complex architectural designs. | Feature | Description | Practical Benefit |
Dialux 4.3 produces arguably better looking printed reports than EVO. The PDF export in 4.3 is clean, table-based, and exactly what contractors want to see on site. EVO’s 3D reports are pretty but often considered "over-designed" for tender documents.
Dialux EVO introduced a completely new 3D engine based on Building Information Modeling (BIM). While powerful, EVO requires users to think like architects (rooms, building elements, furniture). Dialux 4.3 uses a "Room Editor" that is linear and spreadsheet-like. For engineers who just need to prove a Lux level on a work plane, 4.3 is faster .
: Runs on older Windows environments like Vista or XP, making it a staple for maintaining older systems.
