I saw a flash sale for the NiteFox K3 AAA keychain flashlight somewhere on here a week or two ago and grabbed one, as well as a U05 micro usb rechargeable headlamp. I give a little run thru of them in the video. The K3 was about $6 bucks on sale and the U05 is under $10. Seem to be OK budget lights for the $$ that get the job done.
