Long press the metal side to turn off the light. Crystal clear light diffuses all around, adding a wonderful atmosphere to your room Very beautiful play of light. 16 colors and 4 lighting modes give you more fun to enjoy the lamp Touch control adds mysteries for this lamp. You can also stay in your place to control everything remotely Since they are rechargeable, you can also take them outside in the summer Perfect gift for mother, daughter girlfriend and friends. I highly recommend for color lovers!
