When the switch is off (all the LEDs on the switch are glowing very slightly), ... but has recently changed course and has acknowledged the use of this to remove the dim glow your are seeing. This means that the AC voltage on the hot wire can still slightly power the leds and/or the capacitors in the light bulb, leading to a few milli or micro amps of current to flow through ultra efficient leds, lighting them up. With LED lighting using AC (whatever voltage), even with the switch for the circuit in the off position capacitance and inductance affects that circuit because a lot of the time there will be high voltage on the live wire to the switch but nothing on the return wire to the LEDs when switched off. http://www.noushouse.com.au/store/product-info.php?Clipsal-LED-Dimmer-Fix-31LCDA-pid620.html, https://s0.yellowpages.com.au/83a0c...lectrical-services-carwoola-2620-document.pdf, VerticalScope Inc., 111 Peter, Suite 901, Toronto, Ontario, M5V 2H1, Canada.
