Review on 🔮 ErChen 51 Modes 7 Colors + Multicolor LED String Lights: 49FT Color Changing Fairy Lights with Remote Timer - Perfect for Christmas Party Bedroom Décor! by Victoria Smith

This is a fancy color changing string light where each RGB LED can change color independently. The cord has a wall power supply that connects to the mode controller and it connects to the light string via three wires, two for power and one for data. The mode controller 51 sends color sequence information to each LED over the data cable. Each LED has its own addressing. Although there are 51 different sequence modes, many are very similar. There are only about a dozen really different sequences. The entire chain can be set to any of the 7 colors, or you can select multiple modes where the lights change color somewhat randomly. There is a button on the mode dial to switch between different sequences, or you can use the remote control to select colors or sequences directly. When the string is turned off and on again, it will remember the last mode selected. Very nice fairy lights, but at a high price.
