3W RGB 3535 SMD LED (Pack of 1000) 2.7k ohm Built-in electric reset circuit andThis is a High Quality RGB Colour SMD LED in a 3535 Package. These LEDs consume low power and generally produce a wide angle of light disbursement which can be narrowed through the use of external lenses. The Forward Voltage of Red is 2. 0 2. 2 volts, Green is 3. 0 3. 2 volts and the Blue is 3. 0 3. 2 volts. SMD LEDs are substantially smaller than lead frame type components, they can be used on smaller boards, with higher packing density, less storage
