【Note: This is a junk item as it no longer turns on】 ※Please refer to the photos‼︎※ It receives power while charging via Type-C. The lithium batteries were charged separately, and each battery worked when put into other lights, so there's no problem with them. The circuit board also looks like it has no corrosion. However, it doesn't turn on. If you can fix it, great! If not, consider it for parts and the cost of the batteries. Batteries: 21700 x 3 (5000mAh) ※Estimated market price: ¥1300 each x 3 When it works, it has a maximum output of 15000 lumens and a beam distance of 555 meters, making it an incredibly bright underwater light. When I took it diving, I could capture wide shots of schools of fish perfectly.
