About luminous stone must read before buying:
Many customers think that the luminous stone is to keep it in the sun during the day, and then it will always shine at night! But don't think so. The so-called luminous stone does not mean that it must be on at night. It can still be bright during the day, but in the dark The luminous effect of the luminous stone can also be shown in the environment with few light sources. Of course, the darker the effect, the better! Just let them absorb the light source (sunlight, fluorescent lamp, outdoor natural light), but the environment must have a contrast of light and dark! ! Then as time goes by, the luminous effect will gradually fade away. The luminous light is short-lived, not long-lasting, but it can be repeatedly absorbed and brightened. Of course, the longer it absorbs light, the longer it lasts, the longer it will last.

Frequently Asked Questions about Luminous Stone:
1. Question: Will the luminous stone emit light and is it invalid?
Answer: Luminous stone is a light storage product. The principle is that it can emit light by absorbing the light source. The light emission time is 8-12 hours each time, and the first 1-2 hours of this period are the highlight period and continue to emit light. The received product does not emit light because the light source is not absorbed during the logistics process. As long as there is sunshine or light for a while, you can shine again.
2. Question: Why do I have sunlight during the day, but it is still not bright at night?
Answer: Because the principle of light emission is to absorb light and emit light, which means that it starts to emit light during the process of storing light. If the light is absorbed during the day, but after twilight, the luminous cycle of the luminous light ends, so you can only see it slightly. The light is weak, but when you turn on the light, you will see very bright.
