This is my edc light. Bought about 4pcs for me and a lot for gifts. Put it every bag with Energizer AA lithium inside for long life :). This is the smsllest and the brightest light I've ever seen in this size. Size is comparable with most AAA lights.
I also have other bigger EDC, like UF-2100, or C8 in car, but Eastward is very good for its size!
I too carry a 2AAA penlight as my edc. My current fav is a Pelican 1920. I have the single AAA version of your 007 and it is decent but doesn’t really compare to the quality of the Pelican or Streamlight lights. They are only a couple of bucks more but are well worth it.
I also believe the Pelican or Streamlight lights are better quality, but they sit up out of the pocket.
The reason I took the Tank, was the clip. It sits right up at the end of the light, so that when the light is in a pocket (button down flap, guard pockets), you can't see or notice the light is there. It's totally covered, due to the flush fit in the pocket. That's a requirement. Nothing showing except a clip, for lights, pens, etc.
I carry this flashlight in my handbag, it is attached to one of pen holders in by bag. I have removed the extension tube and use with one 10440 battery.
