The bulbs come in 12 colors and offer a variety of lighting effects to reflect different emotions. 3 kinds of brightness can be adjusted, 100% brightness > 30% brightness > 1% brightness is used for sleep mode, to meet different environmental requirements. There is also a one-button night light function that can directly provide the darkest lights to meet sleeping needs. Flash mode and smooth mode: Two lighting modes allow you to set the appropriate atmosphere at any time. Flash mode gives you a stage effect when you enjoy a concert or stage performance. Smooth mode allows automatic light color cycle switching in different atmospheres. It also adjusts the pace and creates more surprises and romance. Memory and timing: This bulb can memorize the last color or mode used. Synchronization is intended for environments where multiple bulbs are used together, such as fan lights, chandeliers, etc. When we use flash and smooth modes, the rhythm of bulb color changing can still be consistent. Note: One remote control can control all bulbs. Timing Function: The bulb can be set to automatically turn off the light after a few hours. Cycle length (24 hours) is another surprising timing option. We can install the light in yard, courtyard and corridor and set the cycle time (24 hours). Then the light would automatically turn on and off every day, which would change our lives and make life more convenient. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
