Frequently asked questions about luminescent stones: 1. Q: A glowing stone does not emit light, is it ineffective? A: Luminescent stone is a type of light storage product. The principle is that it can emit light by absorbing a light source. The illumination time is 8-12 hours each time, during which the first 1-2 hours are the highlight period and continue to emit light. The received product did not emit light because there was no absorption of light during the logistics process. As long as you receive sunlight or light for a period of time, you can shine again. 2. Question: Why do I have one day's sun during the day, but it still doesn't light up at night? A: Because the principle of luminescence is to absorb light and emit light, which means it begins to emit light while storing light. If light is absorbed during the day, but after dusk, the luminous period of the glowing light ends, so you can only see it slightly. Weak light, but when you turn on the light, you can see very bright. 3. Question: What is the brightest color of luminescent stones?
