Effectively what they are saying is that the number of lumens is teh same, its just the colour temp of teh light that changes. its this colour temp change that makes teh calc work 'better' with incandescent light.


Jambutty,
I do have one addition, you started talking about the RGB colour palatte, I think you should investigate the difference between the RGB(sRGB) and Adobe colour spaces for when you are talking about digitised colour as there is a significant difference in teh 'amount' of colours that can be described by each

Much obliged for the links. However having been in the electrical industry for more than 30 years I am conversant with electrons, alternating and direct current flow, transformers, coils and the like and gas ionisation etc. But they made interesting reading nonetheless. Nothing like a bit of research to jog the old brain cells.
