Wuben L50 LED flashlight emits as powerful as 1200 lumens but small and portable to carry. The size is 5.46in x 1.02in (L x D) and it only weighs 138g (4.87oz) with battery included. We utilize high-quality material for our flashlights. For example, we use gold plated springs in the flashlights, which are more durable than common springs. The USB charging port of L50 is waterproof itself. It will not damage the flashlight if the charging port is wet. But please keep the charging port dry and clean when charging.
