You may be thinking we have a typo in our text when you see RGBW. However it's accurate, and a little different to regular RGB strip. In addition to the Red,Green and Blue LEDs, there's a pure white LED also. Typical RGB does a fairly good job of giving you a white-ish light output, however nothing beats true white LED. While it might not make too much difference if you're using it for a little illumination while camping, the true-white makes all the difference when reading and using technology. In addition, the extra white provides additional colour-blending options to get even more colour shades from the light. Now you can have light pink, light green, or anything in between, and still have a high volume of light output.
