It would be interesting to find out what it is about the compacts that

of the
phospher or maybe the emission frequencies of the stuff, I don't know.

Probably due to their sharper rise and fall flicker...

Might also be related to their non continuous spectrum.

I must admit I am not sure why the quality of light from the compact
versions seems so poor compared to that from a traditional linear tube
ones.


Agree, I think it is that all CFLs available in non specialist outlets
have a low colour temp (mostly 2700K) probably in an attempt to match
incandescant. To my eyes, that just makes them an unpleasant colour and
seem dim. Linear lamps have always tried to emulate daylight and, at
least to me, preferable.

Also, converting our flourescent tubes to elecronic ballasts has made
them much more pleasant to work in as there is little or no 100Hz flicker.
