According to the lamp base, G4 SMD LED Bulb is a type of LED bulb which use the base of G4, G4 SMD LED bulb adopts SMD LED as its lighting source which makes soldering points steady. L.E.D means Light Emitting Diode, which is a lighting technology used in almost every electrical and electronic product on the market, from a tiny on/off light to digital readouts, flashlights, traffic lights and perimeter lighting. There are mainly SMD 3528, SMD335 and SMD 5050 for SMD LED bulb. G4 SMD LED bulb with high power LED provide long life, which offer clean pure white light and other great color. It is shock and vibration resistant, as well as direct screw-in replacement. G4 SMD LED bulb do not use the older 5mm round LED as used in earlier LED light bulbs. This SMD LED bulb uses the new super flux SMD LED. G4 SMD LED bulb is applied to supermarkets, jeweler's shops, advertisement box, office building or for direct replacement of convention lamps, homes, shopping malls, office lighting, as well as commercial building, villa, restaurant, hotel, table lamb, garden lamp and more.
