Gentlemen, I need some advice.
The case is that there is a company aquarium lighting beam, after connecting the power supply to the socket (and the beam squeaks for some time) or the power supply is not able to determine what, and the second thing - the radio stations are a little hum - which is annoying. I have read other articles (about phases) .. and I have the beam and the radio Hifi set in the same room - connected from different sockets - also from another beam - I have no other way to connect it ... I can do something - buy something 'dynks' noise reduction or something else that will reduce these ailments (but proven methods, and preferably some link to an example item so that I know what to look for on the web).

thanks for the answer and help. I can replace the whole lighting because it is under warranty and it has not been 14 days, but how can I be sure that the new one will not cause problems - and that it is my electrics fault?
