Why does the RGB light strip only light up white?

An RGB light strip that only lights up white usually means that the light strip is set to emit a single color of light, or that the light strip is malfunctioning. ‌

RGB light strips usually emit light in three colors: red, green, and blue. By combining these three colors, a variety of colors can be produced. If the light strip only lights up white, there may be the following situations:

‌1 Manually set to white‌: If the user sets the RGB light strip to emit white light through the remote control or other control methods, then the light strip will only display white.

2. The controller or remote control of the light strip is faulty, resulting in the inability to switch the color or mode of the light, and it can only stay on in white.

3 ‌RGBW light strips‌: Some light strips may be designed with RGBW (red, green, blue and white) colors, where W stands for white and is used to increase brightness. If the light strip only lights up white, it may be because the light strip is set to only emit white light, or because the white LED is damaged and the other colors of LEDs are working fine.

4. There is a problem with the power supply or wiring of the light strip, causing the light strip to not work properly and can only light up white.
