[Boatanchors] OT: Which LED lamps are good and which ones bad (From a Radio noise standpoint)

[Phil]

OK, I'm posting this to several lists (NOT cross-posting) as I want to 
have as much information at hand as possible before buying (they're not 
cheap).

I have a floor lamp immediately adjacent to my operating position, less 
than 12" from the SDR receiver.  As the lamp is typically on over 12 
hours a day I actually 'prefer' to use a CFL in it (Edison Base) to keep 
operating costs down.  Problem is, the CFL generates "hash" in the SDR.  
SDR is in a plastic case and the hash is picked up via the inductors in 
the add-on LPF, as well as any portable radios I set on the operating 
bench and listen to AM on (they have loopstick antennas).  Because of 
this I've been switching off between a CFL and the old style 60 Watt 
incandescent lamps (which I actually prefer, but they take more current 
and burn out regularly).

I've considered the purchase of LED lamps for that position as well as 
the ceiling lamps (takes 2).  The last time I looked they were very 
'pricey', more than I'd like to spend on an 'experiment'.  BUT I thought 
I might go down to either Best Buy or Lowe's and see what they had in 
stock (Lowe's is probably the best place).

Before spending my money, I wonder if anyone could tell me what lamp 
brands are "RF Quiet" and more importantly, WHICH ONES ARE NOISY AND TO 
AVOID!

Thanks all, and HAPPY NEW YEAR. . .
