Inline dimmer switch (24V) is incompatible with dimmable transformer.If not used with wall dimmer switch, plug-in power supply (except 6 watt power supply) can be used to do the hardwire installation, but if dimmer switch is needed, 24V dimmer switch is required. You would need to splice the power plug from the power cord and connect to the power source with a junction box or something similar. Wall dimmer switch (110V) is incompatible with plug-in power supply.Power Supply Start Up timeDepends wattage of power supply, the start up time may differ. Please use matched wattage of power supplies for best result.
