Have played with it several times, quality is very good but don't have runtime results. It's the brightest light I have right now - and I have many. Follows exactly the candlepower forums reference post with some minor differences. Battery pack is the 4 cell.
These guys are really making lighting affordable - materials for such a beast are $30 minimum alone in high quantities. So they're making a very modest markup. Surprised this isn't catching on. Still surprised that there are similar lights being sold for $200+ MSRP.
