Various emitting colours: Red/Yellow/Orange/Chartreuse(Yellow-Green)/Blue/Green/Warmwhite/White/Pink/UV(Ultra Violet)
You can distinguish the polarities by the colour of the wire. It is labled on the box so that you could see clearly.
In order not to damage the diode, please DO NOT use voltage over 12V. The diode would dim as the voltage reduces, but we do not recommend voltage lower than 9V.
