Proton 3V 1W Blue 2835 SMD LED (Pack of 4000) thick film composition TTL logic)This is a High Quality Blue Colour SMD LED. These LEDs consume low power and emit low intense bright light, 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. 2 volt and the wavelength is 450 460nm. 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
