Summary

I think best type of torch is a head lamp when you can lit things and your both hands are available.

I could not find a small EDC head lamp on the market. There are already small EDC lamps like Wuben G2 that are small and chargeable. I think this concept is new to use Petzl type winding head band and connect it to small and flat lamp with 3D printed part.

This concept could be made better with better designed plastic piece that can be attached to the lamp. Anyway I really like this velcro connection as well since I can store this separately with the lamp in my EDC kit.

I found cheap version of winding head lamp where I manage to take the winding mechanism and use it in my build.
