Also, consider wrapping the PS in Aluminum Foil. That may provide some
degree of shielding.
On that point, I have two Direct TV receivers that were prone to
changing channels, resetting, and such when I transmitted. This was
proven to be the broad RF input for the RF remote control portion of the
receiver. No amount of ferrite on the cables helped. Even after they
were switched to IR Remote, no improvement. Finally I wrapped the
units in Aluminum Foil leaving a small 1/2" window for the IR remote
signal access. Problem solved.

Hi,
Jim is correct, replace it... I had a neighbor, and I had several
ferrites on it, all with many many turns of cable, and got very little
positive result, replacing it gave me a positive result... :)
Those things generate a horrendous amount of RFI, and the power cables
to the lights are nothing but antenna... Consider how much reduction
you will need to get to your original noise floor. If you must keep
the PS, then more turns is better. Replacement is always preferable to
reduction techniques.
