I just ordered one of these yesterday. I hadn't seen them before but they look really neat and compact. The one I ordered is made from titanium with a silver finish. It runs on a single 123CR, and is only 2.3" in length. Puts out 3, 40, and 189 Lumens. Also has the strobe and SOS feature, along with a Beacon, Hi and Low. Not sure what the Beacon feature is. It is available in a single AA, with a lumen output of 2.7, 25, and 90. Anyone else have one or know anything about them? Was sorta an impulse buy, but I did like the compactness of the light as an edc.
