More than 20, 000 hours long lifetime, you don't need to change the bulb for quite a long time. With 360 degree beam angle and strong illumination, the bulb is both nice-looking and practical. It only uses 6 watts of power but is equivalent to a 60 watt bulb, energy-saving and environmentally. Easy to install the bulb as the ordinary incandescent bulbs within a few seconds, no tools required. Great decoration to create the festival atmosphere of Christmas and you can enjoy the visual feast.
