Fresh out of test production: Light-Recycler!

Special developed glowing crystals allow this alternative energy product to glow for almost 4 days by one hour of charging with sunlight or artificial light.
10 cm x 10 cm is fully enough for real orientation at night.

For every woman and every man. For indoor and outdoor.
Of course we have to check this first pieces in every aspect of behavior in function, etc.
