New to this forum but would like to know if anyone can help.
Our down stairs lights are very dull at times yet other times glow normally. We have a ceiling light and two wall lights which take 40w G9 halogen bulbs this is really bugging me as we have had an electrician in who checked inside the CU and said everything was tight and ok and checked voltage at a couple of light switches which he said was ok, he checked wires at the ceiling light fittings and said they were ok but i know these do not seem to be glowing properly. I have read about earth leakage and dodgy mcbs and loose mains neutrals, does anyone know if it could be any of these. The upstairs lights are fine so i can not see it being the mains incoming into the house. Our CU is a newish install 16th edition about 8 years ago. Please any help ???
