Just bought a couple Armacost 4 ft. slim LED light fixtures -
very disappointed that they cause radio interference when turned on !
It was not a new issue to their customer service - but they just
recommended that I return them for a refund ... :-(
Has anyone else experienced radio interference with LED lights ?
... any fix for it ?
These are otherwise sweet light units - more expensive
than most - and I'd like to keep them.

"radio interference" is pretty non-specific. AM radio? FM radio? Strong
signal area? Weak signal area? If it is a weak AM signal being interfered
with that is not surprising at all. As someone else posted the proper
ferrite cores applied to the cord as close to the fixture as possible is
one possible remediation but the core has to be chosen for the frequency
range for the best results but will only work if the cord is acting as an
antenna for the interference.

The proper, if painful, path to follow is a complaint to the FCC about an
interfering product -- they are supposed to be tested for and designed to
prevent interfering with communications.


FM radio ; strong signal; in the same room.
Hopefully moot - once I install the lights in the basement.
