compared with the general standard fluorescent materials, the luminous time of Chromalight is almost doubled, and the luminous intensity remains relatively stable during the whole diving process, which can last for more than 8 hours.

noctilucent powder is based on powdered zinc sulfide, which does not emit light itself, but has phosphorescence characteristics, that is, it will continue to emit light for a certain time after being excited by sunlight or light, but for a short time.

in order to continuously excite zinc sulfide, a certain amount of radioactive elements should be mixed.
