quinetic

This is quite an obscure question and was hoping that someone could help me out. Currently have a bathroom running a light & extractor fan that operates off a horrid pull cord switch. I was hoping to change that to a wireless kinetic switch system I found off Amazon, essentially a Quinetic...

I'm looking into using Quinetic receivers for lighting and see a lot of entries on the forum. But I can't find an answer so hoping a user can help. Does the receiver require a minimum load for the lighting. I've had problems with electronic switches before when using standard mains LED lamps...
