This RGBW LED Strip is made with SMD5050 RGB LEDs and White LEDs respectively, it's controllable by the touch screen RGBW controller with various different lighting effects, also we can use the RGBW ampilifier to extend the continuous length of the RGBW LED tape.

The origins of RGBW flexible LED strip light
Since people can't satisfy with the RGB LED strip lights' lighting effect of the R, G, B mixed white colour (it's not as beautiful as the single white LEDs). So we add the separate white colour LED to the design of this NEW RGBW LED strip light to meet the actual application.
