Absolutely! That’s what it’s designed for. Bolleke is your buddy on any summer evening, from sunset until late into the night. Bolleke is splash-proof. A little rain is no problem. But please take it inside during torrential downpours.
Always check to make sure Bolleke is properly closed in order to prevent water damage. The caps must be closed tightly. Also make sure that the 'legs' on the rubber ring are plugged into the lamp.
