I'm wondering about large (100's of watts) discharge lamps that have electronic ballasts. My purpose is to run such from 400hz power sources. I've got a call in to GE Nela Park, but thought I'd ask here, too, if only to give Phillips a chance :-} Secondly, I'm looking for net-speculation regarding running switcher supplies on the same stuff. It should be no problem once you have DC to switch, but ISTM that the incoming line meets a big inductor, and at 6x its normal freq, not a lot would pass. And to round things off, how about wall-warts? I've used normal-sized 60 hz transformers on 400 hz, & can't think of any reason why they would object, but it never hurts to speculate.. -- A host is a host from coast to coast..wb8foz@skybridge.scl.cwru.edu & no one will talk to a host that's close..........................
