I have some strange symptoms with my house's lighting circuit, which I am trying to isolate.
There are two lighting circuits in the house, upstairs and downstairs (although some downstairs lights seem to be on the upstairs ring - which I find strange)
I had 3 GU10 bulbs in a light fitting in the kitchen - two halogen, one LED. This was working fine, until one of the halogen bulbs blew.
I replaced all 3 bulbs with LED bulbs, for consistency and since then I have had a persistent problem that the bulbs are very dim until you turn on several other nearby lights (all on the same ring from what I can tell)
Whilst the bulbs are glowing dim, it also causes interference with our TV reception, which is probably due to a booster unit being wired up to the lighting ring.
My question is: can bulbs cause this strange behaviour? We have had other similar issues, which have been resolved by replacing all bulbs in the house with non-LED/non-CFL bulbs, which seem to cause problems. Or perhaps it is one or more light fittings at fault?
The breaker never trips, which is something I guess.
