FWIW I have an earlier version of this light. Mine takes 3 rechargeable AAA batteries but the newer ones are all USB rechargeable. It has flood, spot, and red for preserving night vision. I use it for auto repair, night bike riding, walking the dog, camping, astronomy (red light), and it is a super useful tool. Mine will last 8 hours or more on high spot but I can't speak for the new ones.
A good headlamp is must have tool.
