The 600 and 601 condenser were designed for 75watt bulbs, a smaller bulb may not matter with 35mm but might with the 6X6 condenser packet. My enlager bulbs are the same size as standard household bulds, I have used GE softwhite bulbs in a pinch while waiting for enlarging bulbs in the mail. Using standard bulbs in a Durst is somewhat easier, as the light souce is not stacked on top of the condenser but is off the side so the printing on top of the bulb does not show at all. On the end of the scale I have used oversize bulbs in my D3, almost like a difussion effect.
