Emergency Fluorescent / Emergency light

This is a simple and convenient emergency light, which can be used in disaster relief or camping.It’s operating principle is similar to the fireflies. There is luciferin on the inner wall of the light. The luciferin will turn into the excited state oxyluciferin as soon as it contact the oxygen in the air. Photons will then be released when the excited state oxyluciferin become back to the ground state. When it’s not in use, fold and button it, so it’s isolated from the air. When use, please unplug it and pull it wide as playing an accordion. The air come inside and it gives light. If the light becomes dim, just push and pull it several times.
