My thoughts won't be too profound.
1) I was so psyched that 750 lumens would be like an antiaircraft searchlight. It's not. It's just incrementally brighter than a now-common 200 lumen light. But it sure ain't bad.
2) But it WILL light up an entire room handily when tailstanding. You really don't need room lights any more unless you're going to stay there a while.
3) It is VERY floody; certainly when compared to an HDS 170 clicky with the Golden Dragon, but even compared to, say, a Quark Mini.
4) The beam has a pronounced lemony fringe, so much so that it doesn't seem to be cool white; at least not when compared with, say, a Quark Mini. On balance it's a very nice tint indeed.
5) The button is so fantastically hard to operate (especially double click) as to be a pain. Right now, given I have no intention of EVER carrying this light in my pocket, I would give anything for the luxurious old style button. Zebralight would DEFINITELY make one more sale if they offered it as an option.
6) Five minutes on high, free standing, does not produce what I would call a scary amount of heat.
7) The Panasonic batteries definitely do get warm in the Pila charger. Enough to cause me some concern.
