have two office lights, wired in parallel that were switched for LED a couple of years ago. For over a year they worked fine. They are the type with multiple little LEDs not LED bulbs. On switching on & off they alternated through warm / cold / middle light.
Unexpectedly both stopped working and now extremely intermittently turn on when trying the switch.
I checked the voltage with an multimeter, all correct at the switch and where voltage enters both light fittings. Voltage is there with the switch on, reading is 244V. I haven't checked around individual LEDs but given the light is intermittently coming on I don't think that the LEDs themselves have blown.
I checked in the loft all wires are still secure, not chewed or loose (as the voltage suggests anyway)
I changed the light switch - no change. the lights came on & off briefly when I changed it but then just as instantly stopped working / responding again.
I changed one of the lights for an alternative light (completely switched the actual light & wired a new one in) - this briefly turned on & off to the switch, then both lights lit when switched on & off & then nothing again.
In desperation I changed the wires for the upstairs & downstairs circuit breakers at the distribution board to see if that made a difference, no change. (all other lights upstairs have been working fine including an LED one in the hall).
what the heck is going on? I don't know where to go with this next!? I'd appreciate any suggestions
