Is there any indication/code on the boxes or any other way of telling what
colour CFL lamps are going to be, before one buys?

There seem to be at least two kinds - one more like the old tungsten, with a
pinkish/yellowish tinge: the other with rather cold greenish/bluish output.
We recently bought a new light fitting that had the narrow screw fittings,
and found there was not much available in this size. The first three lamps
we bought turned out to have a very bright but not particularly
illuminating, cold light, getting towards the colour of led torches. Rather
an expensive way to make the bedroom seem a lot colder and less cosy.

Looking to replace these with the warmer looking kind, I can see nothing on
the boxes in the shops to denote what colour they give out. Does anyone
know of a chart/table I can look at to tell me what I need to buy.

Cheers, and a merry Xmas.

look for "colour temperature" often expressed as "XXXX K" (where
xxxx's are numbers)
warm white is abt 3000K, blue "looks like a closed butcher's shop"
crap is abt 6500k

cheers

Colour temp may be indicated in any of 3 ways:
a) Kelvin figure. 2700K - 3000K is warm, 4500K is cool, 6800K is icy
cold.
b) Kelvin temp and CRI may be encoded into one figure. 827 means 2700K
with a CRI in the 80s%, 854 means 5400K.
c) colour names such as warm white or daylight. Daylights are very
cold icy lbuish, avoid them.

Thanks for the handy info folks:

I've copied it to go on my 'spare lamps' box.

A warm white new year to you all.
