The paint itself emits for a very long time. The most important parameter to take into account is the length of time its light emission is perceptible to the human eye.
In an outdoor environment devoid of any light, we consider that the eye can perceive light emission up to around 8 millicandela/m², i.e. after 10 hours of emission. If the environment presents light pollution (full moon, proximity of public lighting), this threshold will be raised and the duration of visibility will be shortened.
Indoors, in absolute darkness, the perception threshold is much lower, and you can observe the luminescence of our paint for over 12 hours.
