I fitted five 50watt 240VClick downlights in parallel in our lounge ceiling to replace wall lights. There was a two way switch at each entrance to the lounge so I kept the wiring intact but fitted a 400w Click dimmer switch one end. This dimmer started to flicker slightly after a short time then suddenly failed. Thinking it was faulty I took it back and exchanged it. The new dimmer has now started flickering. The guy at the shop said on the first visit that about 10% of dimmers he sells develop a fault. I'm wondering if I have been really unlucky or could there be another reason?
Any ideas?
thanks
