I must say this thread has kept me well entertained for several nights now.
I've researched more in to it and am now more clear (well more clear than before) about it.
Fact:The colour of light matters. Therefore Jambutty is wrong.
This picture from newscientist perfectly illustrates it:
As you can see, quite clearly, the purple and green bars are at the red end of the visible light spectrum, and they don't cover the blue end.
To rephrase that, it means red light can be used and absorbed but blue light can't.
I'll be honest, I don't perfectly understand why it is. I have struggled for many many hours trying to find out, but nowhere I have found explains every piece of the jigsaw, however I think it's ok to accept a respectable source such as newscientist without having to do all the proof myself, as I doubt this would be beneficial as it would be very hard for anybody to understand.
I might not write perfectly, and some of my writing might be open to attack by pedantic persons, but if things are read in context then usually people can understand what im getting at instead of picking at small mistakes I might have left in my English that could be 'interpreted' as me contradicting myself.
At the end of the day, I can't force Jambutty or anybody else who disagrees with physics that I, or any of the websites I have viewed are right.
Jambutty was right in one aspect, it appears the Energy Saving lightbulb that he posses gives out 21 less luminance, but thats 2.6%, it's negligible really, you can't notice the difference with your own eyes (well I certainly can't). To make a link between the solar powered calculator having to be much closer to work though, explaining brightness, is just simply wrong. As I have stated above and quoted a picture from newscientist, solar dosn't work off the majority of (blue) light given off by LE lightbulbs.
I have no doubt Jambuttys mile long speech where he pedantically analyzed my text will probably be his last post on the subject, because he doesn't want to accept defeat, but really, you can't argue with fact, the colour of light does matter.
