Hardwire Installation If you plan to use a wall dimmer switch, you need to do the hardwire installation with dimmable transformer, instead of the included power supply which plugs into wall outlet, due to the voltage difference between the wall dimmer switch (110V) and LED light panel (24V). If not used with wall dimmer switch, included power supply can be used to do the hardwire installation, but if dimmer switch is needed, 24V dimmer switch is required.
