5mm RGB LED is the most popular LED in Through-hole RGB LED.
Same as the 3mm RGB LED, 5mm RGB LED also have three chips in, four pins, common cathode or common anode and those chips can be placed arbitrarily.
The shape of the lens can be 5mm round RGB LED, 5mm Straw hat RGB LED, 5mm pointed top RGB LED and 5mm round LED without flange RGB LED.
For the 5mm RGB LED, the lens can be water clear or diffused. The former has a strong spotlight, and the later lens will make people feels soft.
5mm RGB LED, RGB Dip LED Diode 5mm, 5mm Digital RGB LED, Red Through Hole RGB LED 5mm
