The MecArmy X3S whacks out a huge 130 lumens in a tiny flashlight, not much larger than your little finger!

It is crafted from copper with a real feeling of solidity in your hand. This tiny torch is just 4.6cm long – about the same size as the blade on your car key. It is activated by a twist of the head. As for batteries, you can forget about buying those. It’s supplied with a 10180 Li-ion cell which can be recharged in situ.

This lamp is rechargeable via a micro-USB socket, located in the side of the head when it’s unscrewed from the body but remains attached so will not be lost. It has two brightness levels – a stated 130 ANSI Lumens on High mode, for 30 minutes, or 12 lumens on Low mode, for a quoted six hours. It’s supplied with two spare o ring seals, a USB cable and a keyring. This version has a very attractive copper body.
