Version history

DIALux evo 3.1

  • new copy function for extracts from DIALux evo outputs into other programmes e.g. MS Word
  • removal of an error after repeated Undo/Redo in the DWG tool
  • correction of degrees of reflection in standard colours
  • correction of various translation errors
  • presentation of schematic luminaires in street planning
  • deletion of street variants using the "x" button
  • various small bugfixes

DIALux evo 3

  • material visualisation in CAD for painted and metal materials
  • faster output
  • street calculation according to 13210 with "Tabular street planing".
  • parallel planning with several schemes, e.g. different geometries or arrangements
  • visualisation of the lighting effect of a single luminaire in CAD in "real time".
  • evo "easy“ - a very simplified GUI enabling planning of simple rectangular spaces similar to the function in DIALux Light
  • energy evaluation according to EN 15193 - It is now possible to make a 'live' energy evaluation while planning. There are options for displaying in kWh/a or Leni or showing the costs in any selected currency.
  • Complete 64-bit version - the 64-bit version is not compatible with Windows XP and cannot load older DIALux projects. However there is a much larger memory for saving larger projects. In the setup it is possible to select the installation of a 32-bit version.
  • HDR image export
  • Numerous small bugfixes

DIALux evo 2

  • Export a screenshot as a jpg. or bmp. file
  • Global false colours on al surfaces in CAD
  • WASD control in CAD
  • DWG Export
  • Big improvement in performance, stability and hard disc usage
  • Shift a room and zoom without the scroll wheel(P + left mouse click = shift, Z+ left mouse click = zoom)
  • New floors can be inserted between two old floors
  • Set the focal length of the camera (ALT+ right mouse click)
  • New colour catalogue
  • One-page output
  • Sequence of tools in the different modes improved


  • Wrong translation
  • Unclear behaviour remedied for different types of planning in the field arrangement
  • Underside of the roof has a degree of reflectance of 70%
  • Windows in the ground plan are now always correctly oriented
  • 3D help lines visible in 2D plan
  • Several floor elements can be selected simultaneously
  • Textures can be scaled numerically and rotated
  • The output tree has a better structure and is easier to read
  • Many further bugfixes

DIALux evo 1

  • Planning of whole buildings including outdoor spaces. Merging of indoor and outdoor lighting design
  • Exchange of light between rooms and between indoors and outdoors
  • Simplified and innovative operating concept
  • Very simple building design
  • Subsequent tuning of lighting scenes enables exact adjustment of the dimming values after calculation
  • Rooms know intuitively how many luminaires of which type they require
  • Up-to-date, fast calculation process
  • Ouptut in any paper format
  • Selection of all important specifications by the norm control centre
  • Scaleable interface
  • Automatic room recognition
  • Detailed manufacturer information
  • Visualisation of transparent materials in CAD
  • Calculation under consideration of reflecting materials
  • Visualisation and valuation of calculation results in CAD
  • Realistic building apertures such as windows and doors
  • Dimensioning and labelling directly in CAD
  • Via "drag and drop" it is possible to insert furniture, surfaces ( textures) and luminaires easily i into the room
  • At a glance false colours provide quantitative analyses in complex geometries
  • Realistic textures and furniture
  • Integrated raytracing creates photorealistic impressions at lightning speed
  • Calculation under consideration of transparent materials
  • Planning with LED luminaires and other coloured light sources
  • Planning with colour filters, coloured light sources and coloured materials
  • Interactive 3D-visualisation allows you to walk around the room
  • Integration of 3DS objects into lighting design
  • Import and export of .dwg and .dxf files. Importing and later exporting with results after successful completion of the lighting design. No additional software required.
  • Intelligent components always position wall luminaires correctly on the wall and computers on the table.
  • With one click luminaires are directed at the illumination point
