Anyone have experience with the Osram line of IRC lamps? I had purchased some from FUSA but they don't seem to be around any more. I have a project with 8 of these lamps in a special situation (trying to balance loads on an arbor, limited by the wiring) and want to get some replacement lamps. Anyone have a lead on where to get them? Specifically the G4 base 14w (20w equivalent light output) lamp? Thanks!
