This lantern uses a special LED light instead of traditional nutame bulbs, giving it a warm candle color. The use of LED lights also provides high energy saving, and the power consumption is less than 1/10 of the nutme bulbs, and the long life of the bulb does not need to be replaced. The AC adapter and AC cord are uniformly white to create a divine atmosphere. Place it on both sides of the temple and turn it on when you visit, sunset or dark surroundings and off before sleep. If the place of a divine is a dark place that is hard to get sun, you can light it up from the morning.
