Lights for extremely long!
These phosphorescent film with self adhesive back designed for the safety technology of skyscrapers - hence their unusual properties:
It recharges in a few minutes on the light and glows in the dark, first 20 minutes of fairly strong and then again for 8 hours.
Perfect for the home-made starry sky on the ceiling or luminous markings in dark rooms. Non-toxic and harmless.
