From the project
An open source USB rechargable LED Torch
Generally speaking is to have a decently powerful open source LED torch, Im hoping for 10K lumens and some basic brightness control, anything else is bonnus features but there are some i'd like such as PD charging and being able to act as a battery bank if needed.
