These colour-changing 5mm RGB LEDs take the work out of creating crazy, flashy, blinky ness. Simply apply power and the LED flashlight bulb will cycle through the RGB colorspace: no external controller is necessary. These bright and festive LED emitting light make great decorations, LED “throwies”, indicator lights, etc. The typical forward voltage is 2V.

5mm Blue Led Light Bulb is designed for the application required high luminous intensity.5mm Blue Led Light Bulb, the phosphor filled in the reflector converts the blue emission of InGaN chip to ideal Blue. These LED light bulbs can be used in outdoor displays, optical indicators, backlighting, marker lights, etc.

5mm Green Diffused LED Light Emitting Diode is a semiconductor light source that emits light when current flows through it. Green Diffused LED Light electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the bandgap of the semiconductor.

IR Infrared LED Transmitter And Receiver Pair is the combo of both IR LED & photodiode. IR Transmitter And Receiver, which together can work as an IR sensor module. This is the IR Transmitter and Receiver pair-matched pair used in our IR proximity, White Line, or Micromouse sensor. It consists of a 940-nanometer wavelength high power IR LED and photodiode having a peak sensitivity at a 940-nanometer wavelength.
