Strange thing: the LEDs sometimes glow slightly, even when switched off.
Four different sets of lights are all switched from three locations (2*4-gang 2-way switches, and 1*4-gang intermediate switches), and the brightness of the glow varies depending on what other lights are switched on in the kitchen.
I'm assuming that, because of the length over which all cables are run in parallel, that somehow sufficient current is being induced to illuminate the LEDs, dimly. It probably helps that the cables run along a structural girder for 3 metres.
Do you think this is anything to worry about? I wonder if it's possible to get a dangerous "nip" when changing a bulb? (Not that I'm likely to put my fingers into a bayonet fitting, never mind a GU10).
I know you shouldn't bunch cables together unless suitably de-rated (which these are), but never thought about one cable inducing a current in another cable. Anyone ever take steps to avoid this?
