My wife picked up a pack of these. They run off of 3xAAA batteries, and are brighter than my Fenix L2D premium Q5 (Fenix claims a lumen rating of 180 on turbo, though I have no way to verify that). They are also brighter than the Lowes/Task Force lights (clamed 150 lumens).

The OP stated they are brighter than his Fenix L2D (claimed 185 lumens) but not as bright at his Terralux (claimed 220 lumens).

The actual lumens they put out is unknown, but it seems reasonable to conclude it's somewhere around the claimed 200.
