UL listed?
Its a product Safety standard. Here is a Wikipedia page. https://en.m.wikipedia.org/wiki/UL_(safety_organization)
I'd challenge the restriction. I doubt that everything in the house is "UL listed".
That said, the fear and concern is real. It's why many such products run on 5 or 12 volts.
I'd also check if you are actually switching mains power, rather than sending a separate control signal to the WLED.
