GE Chroma 75. They're retailed these days as "Sunshine"
(not "Daylight") bulbs. They're 5000K, cheap and easy to
get. There's also a Chroma 75 which is 7500K.

C50 emulates noon day tropical sunlight. C75 emilates
noon day northern daylight. The C75's aren't puches into
regular consumer oulets ("Wal Mart") so you'll probably
need to track them down through a specialty lighting
distributor that carries GE stuff and they're likely
to be more expensive than the mass market C50's.
