You can get CFLs in daylight version, marked as daylight or
6500K. Daylight tinted lighting is however hideous. Halogens
come nowhere near it at 3000K.


I've tended to find that "daylight" lighting means lighting with
a colour temperature equivalent to a dull, cloudy day, which
isn't what I need to cheer me up. Halogen is far nicer as it
gives a much "sunnier" light. The tubes used on First Great
Western's trains are particularly hideous.

Quite. Imho the OP would do far better to repaint.


Repaint three rooms vs trying a few different light bulbs? You must
love painting.


No, I understand the science behind the situation.


So you're saying that you know that no amount of jiggering around
with different bulbs will ever produce a satisfactory look? I'm
impressed! Or rather, I would be if it wasn't for the fact that I
know from my own experience that different CFLs produce different
qualities of light.


*Maybe* none of them will produce a satifactory appearance but it's
sure as hell easier to try a few bulbs than repaint three rooms.


Tim


Let us know how it goes then


Not my problem, I just think your suggestions (and attitude) are
particularly unhelpful. To seriously suggest redecoration three rooms to
deal with a colour balance problem produced by CFLs is just ridiculous The


It wont be solved to anyone's satisfaction by replacing cfls. If you
want to try things that wont work, that's fine, but I personally dont
recommend it.


"science" that leads you to believe that all CFLs use the same phosphors
(and hence have the same colour specturm) does not tally with my own
experience of the light quality from CFLs.


I've not claimed any such thing. Once you understand why the colour
issue is happening, then you'll understand what proposed solutions can
and cant work.


That really makes no sense. Different CFLs will employ different
coatings, and hence have output peaks in different places. Some of those
*may* make for a more acceptable rendition of the chosen colour. However
replacing one set of CFLs with another is not the only option. Replacing
with linear FLs (which tend to have a much better colour rendition) is
an other option, as would be switching to LED/FL or one of the various
metal halide lamps. Even LV halogen would be another lower energy
solution than GLS incandescents.
