Looked at a favour for my auntie, dimmer switch smelling burnt. 10 x 35 / 50 w on each gang, and switch rated at 250 w. Her electrican can' t see the problem says its cheap switches. Need a 500 w dimmer for safety sakes. Wholesalers only got 400w 2 gang or 1000 w single. Dosnt want to change to led. Next step if not make sure all bulbs are 30w, but she likes it bright. Anyone used one as per title
