I've sorted this problem already and all is well, but I'm just curious ...
(apologies in advance if I'm being thick )
Bulb blew in hall light today. Straightforward one-way switch on downstairs lighting circuit. Replaced bulb - didn't work. Tried bulb known to work from another light - still didn't work.
Traced problem to loop-in connection inside ceiling cavity, where the switched live into the light had come slightly adrift from its connection.
Question is - was the blown bulb the symptom or the cause of this?
Will a dodgy connection in a lighting circuit always blow a bulb? (although I can't think what would have caused the connection to come adrift - no recent work or movement in that area). Or are there circumstances in which a blown bulb might cause a physical failure in a connection (maybe in a connection that's already prone to failure)?
As I say, just curious, and hopefully not a stupid question ...
Cheers
