I'm hoping B&M releases something like
the eyro front light with more lux and running time, the eyro is a few years old but I put it on my road bike for riding brevets up to 300k, pretty unlikely to need to run it for more than 5 hours.
look into the B + M IXON Space. Rose has it on sale AND they will ship to the USA. Many power levels and decent battery. From some online forum members, it can also be powered from an external powerbank.
