Is the starry sky lamp easy to break down?

Generally speaking, it has a long life, but it depends on how you use it. The current should not be too large, less than 20 mA.

The small way to check the starry lights is to electrify them. If it is not a live inspection, it is very inconvenient to check because of the long line. Let it charge first, and touch a light bulb in the middle with a test pen. If the neon bulb of the test pen glows, it means that the damaged bulb is between the bulb just measured and the zero line. If the neon bulb of the test pen does not light up, it means that the damaged bulb is between the bulb just measured and the phase line. Then measure the middle bulb of the damaged part of the bulb. If the neon bulb of the test pen glows, it means that the damaged bulb is between the bulb just measured and the zero line. Take the middle bulb in turn and measure it, and you will soon find the damaged bulb. If you find that the light bulb is damaged, you should short the light bulb and turn it on to see if the light will be on. If it doesn't light up, it means that more than one light on the line is broken, and more than one light is broken, or the wiring is broken.
