Dialux is not proprietary to Fagerhult. They are but one manufacturer of lighting and lighting systems who have prepared materials to conform with the Dialux software. As I recall there is no charge to the end user for using Dialux. Its only drawback is that you have to create lighting scenarios outside your own CAD environment.
The idea of ArchiLUMOS is appealing from the standpoint of being able to use photometrics from real sources - i.e. the data prepared for the luminaire itself.
What ArchiCAD needs perhaps is a Dialux Plug-In. I make this comment with a Building Simulation bias and not to simply render the pretty picture. When my electrical engineer tells me we're after a target of 350 LUX in a study room as opposed to the 650 LUX in the existing hallway outside, I'd like to be able to see the difference between the two rooms and from there start work on the design of a shading device to deal with the light spill.
The idea of Dialux is appealing for its vendor neutral standpoint and its relative ease of use. In the building simulation world, there is all sorts of desktop grade stuff out there. Unfortunately it typically comes from a manufacturer and works only with their equipment, OR, its my wide ranging and requires outside consulting power to make it work.
Graphisoft should really put the time in to an integration of CYMAP with ArchiCAD. It would be a huge project to pull off and its seems that they have retreated from the immensity of it - CYMAP is now only available in the UK.
Buildings aren't just about the architectural bits and the electrical bits and the mechanical bits all cooked up in 3 sets of drawings - integrated design requires tools for all the disciplines to use. A CYMAP enabled ArchiCAD with Graphisoft's commitment to IFCs would kick the poop out of AutoDesk. They, too, are taking a non-integrated approach to the problem.
