Something dynamo based if you want to keep it for life IMO
My current bike light is a bit of the opposite - a Towild DLite with a non-replaceable 21700 battery inside. It has a remote for the handlebar, so I can switch between the two beam angles to avoid blinding other pedestrians/drivers, and also functions as a USB-C powerbank.
Really hoping I can replace the battery when it eventually gives up the ghost - might need to 3d print a replaceable back for it or something

Power banks are much more efficient and effective than generator hubs anyway.
