The glow-in-the-dark Therm-o-compass RIDGE Ver.
A new luminous type has been added to the Therm-o-compass RIDGE Ver.
This product uses a phosphorescent material that absorbs ultraviolet light or light, stores energy for a certain period of time, and then emits light in the dark.
When light is absorbed, the electrons in the material are excited to a higher energy state, and over time they emit light as they return to their original lower energy state.
This light is emitted slowly, so it appears to glow for a long time in the dark to the human eye. It continues to emit light for up to 6 hours. (Manufacturer's nominal value)
It increases visibility inside a tent at night, so we recommend attaching it to pouches that you use frequently.
