Well, it's not $35, but it's not much more https://www.blackdiamondequipment.com/en_US/headlamps-and-lanterns/revolt-BD620631_19_cfg.html#cgid=lighting&start=15
Runs on AAA that are rechargeable (via USB). been using it for a year and also have the Storm. Well worth just getting the revolt. Save the money in the first month not buying batteries (if you use it a lot).
