[RFI] LED light bar RFI

[Dan Kovatch]

I have several nice LED light bars as under cabinet lighting. Very efficient
power wise but they make more RFI across all the bands up through 6 meters
than the old switching supply I had with halogens. They use a 'constant
current' wall wart type supply and replacing them with a linear transformer
supply causes low light output probably because of the lack of constant
current. Another LED bar across the kitchen (different make) has no issues 
with noise.

I have tried ferrite beads to no effect. Has anyone had luck taming these 
critters?
