Nitefox UW360. I reviewed it at [review] Nitefox UW360 as well as on Amazon.
Got one review unit, ordered a second because they’re so handy.
Flex-neck, 18650, pure flood (mule), usb charging, tail-magnet (stands on its own by magnetic-suck action and also has a baseplate to use as a standalone floodlight).
Weird little puppies, but I like ’em a lot.
