I got a ShiningBeam S-Mini. Here are some remarks:
1. It's very lightweight, 90 grams with the battery installed, and really compact. This is the first 18650 light I've had where I felt like a standard TwoFish LockBlock was plenty (versus the heavy-duty Cycle Block). It's actually lighter than my 1xAA Romison.
2. Bryan at SB did a runtime test and it looks like you can expect 2 hours easy. runtime graph from CPF
3. The beam is somewhat like a Fenix L2D, with a fairly large, soft-edged hotspot, but considerably more output.
4. It has low, medium and high, and remembers the mode you used last (yay!).
OK, beamshots. Right-click the links below, open them in new browser tabs, and then you can toggle directly back and forth between any two lights for easy impressions. You're looking down the length of a ~20-meter basement in a bike shop.

Fenix L2D Q5 2xAA, on Turbo This is known to be about 145 lumens out-the-front.
Romison RC-2R4 II, on High This is an 18650-powered light, fairly burly compared to the svelte S-Mini.

Naturally, all the photos were shot with locked manual camera settings so they can be compared directly.
