Reduce Noise ripple form Constant Current power supply. Maybe low pass filter?

[wrightpt]

Hi,

I have the following power supply: HLG-120H-350A

I took it to a local tv technician to measure the noise in the circuit. He said it was around 7.2Khz. Nothing in the circuit can create noise. Just LEDs in the circuit other than the power supply.

I was wondering if a low pass filter would work in dropping the noise coming from the power supply? I have not been able to find anything off the shelf that is really suited for this. I think i may be looking at it wrong.

But wouldn't a low pass filter work in calming the noise? At least in theory.
