Livolo dimmer switches are compatible with incandescent bulbs or dimmable LED bulbs (with light intensity adjustment). Using other types of bulbs (even standard LED bulbs) will cause the switch to burn out within a few weeks, not on first use. We do NOT recommend using Livolo dimmer switches with dimmable light fittings whose intensity is adjusted by repeatedly pressing the switch.
The dimming function is performed only by the main switch (the one connected to the wire from the bulb). The other switches in the circuit will only turn the circuit on or off.
A maximum of 3 switches can be connected in the circuit (intermediate / cross switching)
