The advantage of using the HID150 lamp is its brightness, easy availability, long life and low cost - I pickled up four for £160 from Ebay, all new sealed and unused - that's basically 4000 hours of crisp white light, on my modified GS1200 which was previously a halogen 200w ESC based machine it is now as bright as my sold Elmo GS1200 Xenon ever was. These lamps have the advantage of being almost perfectly pre focussed for the 8mm frame, yes a suitable ballast power supply does have to be fitted, and they are best suited to feature length shows as once they are lit and warmed up re-igniting should be avoided to preserve the lamp life.
I would estimate about £350 would cover the parts and labour costs by our favourite UK service experts (in my case Mr Bill Parsons).
Tom - flog a couple more Raise The Titanic digests on Ebay and you will almost be there! - I'm pretty sure your ST1200HD could be modded as it has a shutter (used to dowse the lamp in standby) so a power supply, lamp and permanently on fan is all you will need. Sincerely I can't imagine even considering watching a 'scope film now on a standard halogen projector these HID lamps make such a difference to any bigger screen shows.
My next plan is to modify (myself this time) a recently purchased Elmo 16AA 16mm projector to HID just need more spare time to start and finish it. Again once done it should be on a par brightness wise with the Elmo 16CL xenon I sold.
