Lightrap was made during a workshop aiming at conceiving an appartment without using petrol.
Lightrap is a phosphorescent ceiling that loads during the day, allowing a 12h long free luminosity during the night. Pigments used for its cloth are non toxic and stronger than ordinary phosphorescent pigments.
