So I have just received a Braun Paxiscope 650 and the bulb didn't make the delivery. Turned it on and the bulb died. This is the same as the Artograph MC 250 essentially. Rather this is the 220 volt original that was later sold in the states as the MC 250. The bulb it uses is an OSRAM 64540 with a GX6.35 socket. Now as knowledgeable as that might sound, the one thing I don't know is wether or not this bulb uses a special ballast or not. If it doesn't then I could take an LED with the same socket designed for AC power and swap it out. Sounds simple enough right? However the lumens may be an issue as the original is something crazy like 2000 lumens. I would prefer to do this without rewiring the unit and I assume I will just buy a power hungry original bulb if it isn't possible. So has anyone used this style projector? Has anyone attempted a more efficient bulb replacement? Is there a high voltage ballast lurking in there? Anyone? Thanks in advance!
