This product can emit light without using any electricity, at any time and at any place you like. You have only to crush it flat with your fingers. It will provide light of comfort for the sufferers at the time of disaster.
It is safe as it does not give off heat. It emits a soft light with the same chemical reaction as the firefly does. When the yellow liquid in the capsule mixes with the transparent liquid around it, it emits light. You can adjust its brightness and length of time by the number of the capsule you crush at a time. You can put it on something flat, hold it, or hang it.
