One of the great things about replacing the now obsolete compact fluorescent light bulbs with LEDs is you can now have dimmers again. This handy little dimmer has a 2.1mm jack and plug at each end, so it is drop-dead easy to connect between your LED strip lighting and power supply. The dial not only dims, but also clicks to shut completely off, so no power is drawn in the off state.
