To turn off the lamp, just hold down on the touchpad for 2-3 seconds. If you turn off your lamp, it will not turn off the other lamps in your group.
However, your lamp will turn back on if someone in the group touches their lamp to send a color.
If you wish, you can set up a Sleep Timer on the LuvLink App so you don’t have to worry about turning it off at night.
The sleep timer will only affect your lamp. Each person can adjust their lamp's settings - brightness, dimming time, sleep timer and it will only affect their particular lamp.
