The «Overnight» mode is to be understood as glow of the lantern throughout darkness hour at presence a sufficient number of sunny days (to be specified with reference to the terrain).

The lantern has a reserve of stored energy for operation during periods of low solar activity (the parameter is specified in the table drawing)
