Question: When the luminous powder is received, it will not shine, is it invalid? Answer: Luminous powder is a light-storing product. The principle is that it can emit light by absorbing the light source. Each light emission is 2-8 hours, of which the first 1-2 hours is the highlight period and then continues to emit light. The received product does not emit light because the luminous powder does not absorb the light source during the logistics process. Just put it in the sun or the light for a while to re-illuminate. 2. Question: Why is it not bright at night when I bask in the sun during the day? Answer: Because the principle of luminous light is to emit light while absorbing light, that is to say, it also starts to emit light during the process of storing light. If light is absorbed during the day, but after dusk, after the highlight period of luminous light, you can only see a little weak light, but at this time, turn on the light and light it again and you can see that it is very bright.
