Today, let's take a look at a powerful Skywolfeye "90 000 lm" 5-mode zoomable LED flashlight from Ebay that runs on two rechargeable 18650 Li-Ion cells. Let's test it, do some measurements, open it, reverse engineer it, explain how does it work and see how well it's designed. You can support me on Patreon: / diodegonewild
