Lumintop Tool AA 2.0
This little light has been wonderful for me for over three years. It's always in my pocket. I have taken it on multiple thru hikes now. Clips onto my hat very securely. I wear it as a cycle commuting head light. It's just perfect. And affordable!
I should pick some of these up for gifts, especially since they come in more colors now. Are they dual fuel?
Yeah, only concern is the tail switch aux light coming on when using 14500 and draining the battery when cell voltage isn't checked for a while. If you're gifting to normies, I would pull out the tail switch and put a screwdriver thru those LEDs, or just desolder it, or just tell them to keep it stored with tail cap unscrewed slightly.
They will run off both a 14500 lithium battery or a standard AA battery. Although the output is much worse with a standard AA.
I always use the lithium ion battery. Amazon has a light and battery combo for 30$ usd.
