I was in a Best Buy store again and picked up this light.
I really like the push button switch - click once for high, twice for low, 3 times for blinking (never use that one), and once it has been on for a few seconds, the next click is off.
It seems bright and has a lot of flood. Brighter than my Nano but the Nano's batteries are getting old so it may not be a fair comparison.
The case is metal and it has some nice weight and feel to it. The metal case is recessed around the exposed led so it helps reflect the light out for some nice throw.
It has a white led but seems to have some very light blue tint to it on a white wall (similar to the Nano).
