Does Lantern Festival cost electricity?

There are three kinds of lanterns in the Lantern Festival industry: 1, long bulbs, about 3 cm long, and thick chopsticks. This is a lantern bulb produced a long time ago. It consumes a lot of electricity and is very cheap. At present, the production is relatively small.

2, rice bubble, about the size of soybean grain, this is one of the main vacuum tungsten filament bubbles at present, with low power consumption and low price, and it is the most popular holiday lamp on the market.

3.LED is about the same size as a rice bubble (the main difference between the two is that the rice bubble is glass vacuum-pumped, painted outside, fragile, and LED is epoxy resin sealed semiconductor material, which is not fragile), with low power consumption and high price, especially high brightness white light, blue light and green light.

According to the landlord, the power of the above three kinds is not easy to determine, so the working voltage of each kind of light bulb is different, and each string is composed of several circuits, so I haven't seen it or known it.

But in the case of the same brightness, energy-saving lamps save electricity; If it is an LED, the power consumption is close to that of an energy-saving lamp.
