This 12V Inline LED Dimmer Switch allows you to dim our linear and spot lighting LED products (strip light and pucks). Simply plug this easy-to-use LED 12V dimmer switch into your 12V adapter at one end and your lighting source at the other. Dimming is achieved with a turn of the smooth and sensitive rotary dial, which is housed in sturdy plastic. It can also be used as an on/off switch, but with all the added features of a dimmer. This switch has a wattage limit of 24W: we recommend that fixtures connected to this switch should use no more than 24W of electricity. Available in a Black or White finish.
