Wrong. A 220v/150watt opalized bulb is not the same as a 110v/150w..
A 110v bulbs draws twice the current. The load is also quite different.
If it uses condensors and the typical screw-in opalized/frosted glass
lightbulb you can replace these at your final destination--- wherever that
is. The motors could pose a problem. I nevered owned a Beseler. Are they DC
or AC motors? Any transformer running to them?

OK.. You have a 450/500 Head on a laborator? The fan at least on my Durst
is, if I'm not mistaken, a 220v axial. The power supply is just used for
switching--- but I'd need to check.

The Colorstar could pose a problem as you have the 3000 model which has the
enlarger switch integrated--- like some Jobo gear--- into the power input.
You may want to use it to drive another switch/relay should you want to use
it to control 220v gear.
If you are going to Europe you may want to consider selling it in North
America and getting a 220v model.
