Assalam o Alaikumdoes pak army used cree flashlights or do they use those cheap tin foil bulb torch.
i got a few of these even build my own from driver circuits and t6 led. best bit is i had old laptops, i just crack the laptop battery case open and get 10 batteries 18650 lithium that i can use in the flashights.
Man you are one geeky self reliant scientist
Wish i could do such projects
