Ever hear of a thing called RGB? Red, Green, Blue? How about an RGB LED? These 5mm units have four pins - Cathode is the longest pin. One for each color and a common cathode. Use this one LED for three status indicators or pulse width modulate all three and get mixed colors! These LEDs are diffused; so they’ll appear dimmer, but have a wider viewing angle.     Features: Forward Voltage (RGB): (2.0, 3.2, 3.2)V Max Forward Current (RGB): (20, 20, 20)mA Max Luminosity (RGB): (2800, 6500, 1200)mcd
