OK. By the sounds of it, you have a condenser head that uses filters either under the lens or that are popped in a draw above the negative. The bulbs that you are using should operate just fine on UK mains. If they are blowing after a short period of time, then you either have a faulty batch or your supply is outside the acceptable tolerances. To confirm the latter, you'd need to install a meter and log the voltage variations over a period of time. Unfortunately, this sort of equipment is neither cheap or very common - You could contact your energy supplier and ask for a monitoring system to be installed on a short term basis.
