Yet another variant of the classic rechargeable LED keychain lights. This one has fairly decent functionality even if it is using very dubious circuitry for driving the LEDs.

It has a proper lithium cell charge circuit - minus the capacitors, and fairly functional software with the handy feature of turning off instantly instead of having to mince your way through every mode.

The use of a standard 14500 lithium cell means there is some reasonable upgradability to the unit.

This light came from AliExpress (not a sponsor):-

It's available in four colours, and may pop up as a cheap option in the bundle deals section of the site.

I'm currently travelling with work, and do not have the data I mentioned in the video with me. Suffice to say it was giving the LEDs a very hard time and the cell was not outstanding. It's a functional light, but not one of the best.
