Proton 3V 0.5W Warm White 2835 SMD LED (Pack of 4000) common anode It uses ESP8266 Wi-Fi BoardThis is a High Quality Warm White Colour SMD LED. These LEDs consume very low power and generally produce a wide angle of light disbursement which can be narrowed through the use of external lenses. The Forward Voltage is 3. 0 3. 3 volts and the Colour Temperature (CCT) is 3000 3200K. SMD LEDs are substantially smaller than lead frame type components, they can be used on smaller boards, with higher packing density, less storage area, and smaller
