Use the remote control to set the timer and dim one or more of your STOFF LED lights simultaneously. The remote control has 4 different timer options that automatically turn off the LED lights after 4, 6, 8, or 10 hours. The remote control also features a 3-position dimmer switch to create the perfect atmosphere in your home and extend the battery life. When using the OFF button on the remote control, the LED light enters standby mode. In standby mode, the lights still consume a small amount of battery. If you want to completely turn off the light to save battery life, unscrew the light by loosely twisting the bottom.
