bought a floor lamp, which has a touch plate
I measured the lamp wasting 2.2 watts when OFF
That's half the power my laptop uses.
that's a touch plate switch, so the lamp contains a hidden black box with a microcontroller that sits in a tight loop waiting to detect your finger
luckily I rewire all lamps in my house as soon as I buy them, to convert to 24v dc
this lamp will end up using less power while ON than it did while off in the factory configuration

Project 62 Valencia lamp wasting 2.5 watts.
at least the circuit board that connects live AC to a metal plate on an ungrounded frame does have decent isolation :P
