Funny, I have three sets made by GE - 8 lamps total - that use some sort of
switching black lump, and they are totally RF quiet. The only problem is
that something -- probably their overtemp sensing -- is unduly fussy, so
the darned things keep shutting themselves off...
Wouldn't something like this be soluble by the same sort of filtration as
other switching power supplies?
