Thanks for all the advice.

She likes mainly to paint. I don't know if that would have a bearing on the
choice of tube colour.

Hi, just caught this by chance. Yes it would, very much. If she's
serious about it you'll want full spectrum tubes, and avoid all the
others. Such tubes are more money, but still worth it.

Most fl tubes are a mix of a limited set of flourescent colours which
gives a discontinuous spectrum: the bad tubes (cool whites) use few,
while the better quality ones use a mix of more frequencies to give
good cover, but if you need 100% on the mark colour rendering across
the whole spectrum then you need the more specialist tubes that will
do that.

Still going to be a better option than filaments, will give better
colour rendering than CFL, which are just folded fluorescents. The
other option for serious art work is halogen, which is full spectrum,
but much more power hungry than fluorescent, and the bulbs run
intensely hot.
