The 20mm LED is something very special and fascinated me with its full, by Gallium Aluminum Arsenide Red Light Emitting Diode. In addition to the usual 3 or 5 mm in diameter distributed LEDs has the fun with this kind of LED a bit to try around. The beautiful shimmering color I have been able to capture only partially with the photos. Can operate in the range of 5.55 -7.5 volts.
