Massdrop has the 2017 version of the ReVolt headlamp for $39.99; retail is $59.99. It’ll drop by another dollar if they meet their threshold (big deal, right?).
Specs are up to 300 lumen, 25 hours on high, 180 hours on low, and 3.1 oz with batteries. It runs on 3 AAA alkaline or rechargeable NiMH batteries, and apparently comes with a set of each, according to the info on Massdrop.
Disclaimer: Yeah, my Massdrop referral code is in there in the link.
