The S2i is a simplified version of the Search S2 10000 lumens search flashlight, it focuses on the spotlight with a single high-performance LED and optimized new deep reflector, thanks to the new reflector, it has a max 500 meters beam distance.
Like its older brother - Search S2, it uses a display to show the remaining battery voltage to know how many hours you can use the light until you need to charge it via the USB-C port, the S2i uses 2x 5000mAh 21700 battery to support a long burn time. And the strong magnetic tail makes it possible to attach to a metal surface if needed for work that uses two hands.
