Lumin
Originating from the mineral phosphorus, and observed in nature as early as 1000 BCE in both fireflies as well as glow-worms. It was first isolated in 1669 by the German physician Hennig Brand, who oddly enough was looking for gold through a (ahem) unique process. Happy accidents being what they are, he discovered a substance that had several (ahem, again) properties, including the ability to glow in the dark. Since its discovery, it has been used in countless applications. For Lumin, the exterior employs a phosphur, emitting light after coming into contact with a light source, and continues to glow. This makes our specific application a phosphorescent. The etymology of the name is derived from the Greek word, phosphoros, which meant, “bringer or light”
