Forgot to add: the figures for the fluorescents are for 18 W T8's 32 W are about 30% more effecient I think, I'll have to look it up!

So I spent the weekend using excel and the graphs of the spectrums of differing lamps to make a comparison that rather suprised me. The Fluorescent spectrums are from Osram which I believe is Sylvania in the states the High Pressure lamps spectrums are from Sylvania. There shouldn't be much of...
