I think you would just need a variable transformer for your voltage range. Dropping from 230 to 210V should increase the lamp life a lot.

I know the Durst bulbs for the 138s are out of production. If others aren't now, they will be at some time. I personally have switched my Durst over to LED, but still occasionally put the incandescent bulb back in test how well the LED systems I designed are working compared to the factory setup.
