This unique flashlight saves a lot of energy: In addition to using energy-efficient LED bulbs, the entire body can be split into two, with solar panels hidden in the middle. When the battery is out of use in the field, the flashlight can be turned "on" and charged with solar energy. In addition, when the flashlight is turned on, it can also be suspended and used as a pendant light.
