The Fenix E01 V2.0 is a keychain flashlight that runs on one AAA battery and puts out up to 100 lumens from a Cree XP-G2 S3 LED. You change modes by twisting the head through three levels, and the built-in key ring keeps it on your keys. It is IP68 rated and draws no standby current, so a battery left inside stays ready. Against other AAA keychain lights it trades a tail switch and higher outputs for simplicity and a sealed, drain-free body; owners rate it highly for everyday carry.
