Product Details
MPN: RFI-LED-LIGHT

Add 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.

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise.  Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.

We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener.  Maximize the distance from the camera to the openers may also help.  Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.

Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
