They are the R7 78mm type 150W i think - fitting aappears ok - must say previous light had well blown.Duff info in previous post, if pir live and switched live temp joined, the light will be live no matter whether switch is on.
What type of light is it?,check for damaged lamp to fitting connection(pins).
Lighting circuit im presuming though haven't found where live to pir comes from yet.How is the switched powered, is via lighting circuit or a fused connection?
How did you isolate it when disconnecting the switch?Lighting circuit im presuming though haven't found where live to pir comes from yet.
Yes im going down that route but i like to know what problems are - i only change like for like and was going to change the switch for a chrome one but will not do until this problm resolved.I think in your case and with the information given, it is advised to call out an electrician, I cannot see how your problem can be resolved without an on-site visit.
OK just to make things even more confusing - wifey says all now working as should - can only think that sensor iffy. but what about 230v on switched side -!!!!I cannot get my head around why you have switch live conductor measuring 240V on an open circuit. Without seeing what is what I cannot offer any informed advise. I ask about the fuse connection unit just in case the light was powered via a socket circuit and maybe someone had connected reverse polarity in the FCU and by coincidence the fuse has failed.
Can I assume that the switch did at one time function and operate as an on/off switch?
