>>1968665Excessive as in you'd need to carry an external battery to power it, which automatically makes it last 10+ hours at max brightness if you power it with a 10 Ah bank and requires another bag or strap, unless you already ride with a large top tube bag.
Picrel. I'm that autismo. These lights do indeed seem to have a li-ion regulator with a shutoff at around 3.2 volts, regardless if the other end is USB or a cylinder dc plug. So I just bypassed my powerbanks' boost converter to avoid unecessarry losses from double conversion.
It worked, but then I got a towild br800 and enfitnix navi800 and don't use anything else anymore. On multi-day trips I just charge them while riding.
Also, having lights that are too bright can have the opposite effect unless their beam is really really honed in. The light can make your pupils shrink and make you not see what you otherwise would in the dark.
