Which light sources for repro stand?

[ForenSeil]

I've bought an repro stand light this one from Hama for 4x100W
I hope its I good one.

Any idea which lightsource/lightbulb would be suitable?
Daylight energy saving lamps might not have the optimal spectrum?
Do halogen bulbs work better?

daylight fluorescent such as this one are the best in my personal experience:

If they are flicker free only...

A tri-phosphor compact fluorescent with daylight balance would be my suggestion. Buy ones specifically designed for photography. Tri-phosphor should prevent the greenish cast you get with normal fluorescent lamps, which is the result of green being the dominant colour of the mercury vapour discharge.

I don't think you can get incandescent lamps with a daylight balance. This would require a black body temperature of ~5500K. Tungsten, for example, melts at ~3400K.
