Big fan of Fenix. Even bigger fan of 4sevens lights. Very good and fantastic value for money, respectively.

I have a quark mini AA on my keychain. Just a tiny hair bigger than most AAA lights, but 2.7 times the capacity. Twist on = light. Twist off, then on = more light. Repeat = even more light. I am a big fan of sophisticated things that are really supersimple to use.


Ligth levels: 3 lumens = plenty enough for most close proximity things. Used most, and comes on first. 10 lumens = look for something in a large living room. Close to 100 lumens = look for something in a football field.
