Review on BrizLabs 66ft 200 LED Multicolor Christmas Fairy Lights with Remote Control - Color Changing Christmas Lights Plugin Twinkle Tree Lights for Xmas Party Room, Unique Pause/Play Outdoor Christmas Light by Julie Gomez

The fact that these are RBG bulbs may not be immediately obvious to some (like me) and even if you do know, you may not know what it means to you, when you buy them. The lights themselves can only produce color from a combination of pure red, blue, and green light, any color that isn't pure red, blue, or green looks weird. Not only are these secondary colors not pure, they also leave a strange afterimage in your vision where you can clearly see the composite primaries that make them up. For example, if you set them to purple and shift your gaze while looking at them, you'll see pure red and blue in the motion blur caused by looking. This may not be a problem for you, but I know it for me as I just want the light to be adjusted to pure red, blue or green only because of this effect. Hope this information is helpful!
