which would be more acceptable.

They aren't acceptable to most people, which is why they will be hard
to find. The lux level required to make 3500K look acceptable (lookup
Kruithof Curve) would be hard to achieve with CFLs - you need several
linear fluorescent tubes, which is why you'll find 3500K in fluorescent
tubes, but not CFLs.

The 5000K and up lamps and really just gimicks - you are effectively
using a blue coloured lamp, because you will never get the lux level high
enough for 5000+K to look natural. You would have to line most of the
ceiling with fluorescent tubes.


Not speaking for anyone else, but I find the colour and brightness of the
already-mentioned trumpet top CFLs to be pretty darned good. Far nicer
than incandescent (standard lamps or most halogens). And far far far nicer
than most 2700 K CFLs.

And the 4200 K (IIRC) link lights in the kitchen are not too bad.
