This RGB LED strip is based on WS2812 LEDs. It is packed with 30 LEDs and has a length of 5 meters. You can easily control the behavior of these LEDs either by using the included remote controller or using your mobile phone via a Bluetooth connection. The remote controller can be used for many functions such as selecting static colors, flashing LEDs in different modes, adjusting brightness, and more. But however, by using an APP on the mobile phone, you can have even more functionality.
