Create a vibrant and personalized ambiance with these self-adhesive RGB LED light strips. With the duoCo Strip APP, you can effortlessly control and adjust the lighting from your phone. Whether you want to change the color, activate music mode, strobe, or set a schedule, the app gives you full control. The package includes four LED strips, each featuring nine high brightness RGB LEDs. You can easily adjust the brightness through the app. The LED strips are USB powered, and you can plug them into any USB port. An in-line controller allows you to select different modes, or you can activate music/sound activation. The LED light bars come in different lengths, with two having 1.2m cables and the other two with 1.7m cables. This allows you to place them anywhere, whether it's the front and rear of your vehicle, your desk, or the back of your TV. The self-adhesive strips on the back of each bar make it easy to attach them to any clean, flat surface. Additionally, a remote control is included for wireless control, and the LED light strips are made of SMD5050 LED lights, each strip measuring 220mm long and 13mm wide. The package includes a QR code for the duoCo Strip APP download, a USB power cable, and self-adhesive backing. Note that the surface must be clean and flat to ensure the self-adhesive strips stick well. The APP is not required to use the remote control.
