Interesting. Like you, I don't use my headlamp for night riding (unless the head is a ways from my campsite), but rather for around camp and (mostly) reading at night. I have a more powerful PrincetonTech light, but it chews up batteries like crazy. To combat this, I bought some Watson rechargeable NiMH batteries, but that requires me to carry the charger, which plugs into a normal wall outlet. Since I already carry a phone charging cord with a USB/wall outlet adaptor, this lamp might be a better option for me for longer tours, reserving the PTech light for things like three-day trips.
BTW...Would you please review a stove so we can get a food flame war (no pun intended) going?
