The Hyper Red source color devices are made with Al- GaInP on GaAs substrate Light Emitting Diode. The Green source color devices are made with InGaN on Sapphire Light Emitting Diode. The Blue source color devices are made with InGaN Light Emitting Diode.
Static electricity and surge damage the LEDS. It is recommended to use a wrist band or anti-electrostatic glove when handling the LEDs. All devices, equipment and machinery must be electrically grounded.
