Japan successfully developed spherical battery-powered LED solar flashlight

According to the American technology blog Gizmodo, solar flashlights have always had a significant problem: the appearance is ugly. Recently, a new product in Japan seems to solve this problem. A team based in Osaka recently released their product on the MoMa website. The team has a wide range of members, including architects, chefs, furniture designers and more. This solar flashlight not only looks good, but is also very technical from a technical point of view. The so-called Sphelar solar flashlight is powered by an environmentally friendly spherical solar cell assembled in the handle. Spherical solar cells are capable of collecting sunlight from all sides rather than just from the surface. This LED flashlight can work for four hours when fully charged. The wooden base ensures that the spherical battery can be exposed to sunlight while charging. The flashlight is priced at $150 (about 920 yuan). Of course, with this flashlight, you will never need to change batteries anymore.
