LED Light RFI kit - 1 Filter for AC Power Line RFI Suppression .15-10 MHzProduct DetailsMPN: RFI-LED-LIGHTAdd a ferrite filter to LED Overhead Light fixtures switching power supply to suppress ugly interference back fed into the AC power lies which act as radiating antennas and cause interference to surrounding electronic devices (yours and your neighbors)! Order 1 set for each LED light fixture.
You get a snap on filter (1/4" ID) for the AC side of the power supply.
All ballasts in a particular location must have a filter otherwise RFI may not be suppressed to a measurable value. Suppresses RFI in range of 150 KHz to 10 MHz.
TECH NOTE: You must change the dimmers (if used) to LED dimmers otherwise the dimmers may be the noise generation problem, I have heard that the LUMITRON MAESTRO PRO LED+ are very effective but expensive solutions.
