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?
