Switch – Dimmer switch issue

dimmer-switchledswitch

I have two ceiling lights in my lounge which are controlled together by the same switch. I currently have a dimmer switch and a dimmable LED bulb in each fitting. They work fine although when i switch them off one of the bulb still has a very low glow, and therefore must be getting some power. Any ideas?

I can't find any information about the Superswitch 2701 touch dimmer but from the name alone I'm going to make this guess.

It sounds like the dimmer uses some electricity to operate. And in order to do this, is just lets some current pass through the switch for it to work. Normally, an incandescent bulb would just let this low current pass through it and not visibly light up.

That first LED bulb is bleeding off the current from the switch and it has enough current to actually cause visible light. You can either live with it, or change the dimmer to one that doesn't use any power to operate. Or you can also look for dimmers that will use the neutral if they need power to operate.
