I recently needed something for both running and biking, having previously had an OLD hope vision 2.
I went with this, well within budget

from Torchy to ensure decent batteries and charger and then bought a headstrap from china for 1 whole pounds.
BRIGHT! comfortable on the head as its tiny.
Some people don’t like putting the battery pack in something like a bumbag but as I generally have a bum bag for waterproofs, food etc (trail and fell mainly) and that was the situ for the hope lights then I have no problem with it.
Plus it makes a very competent bar light for the bike
