I handled several of these at this year's SHOT Show and was impressed. I don't recall what the beam pattern was exactly, but I think it was similar to the X200b's flood beam.
One thing I didn't like is that the activation switch only turned on by pushing the lever up (on the right side) or down (on the left side). The X200 will go on with a forward push of the thumb on your support hand. This is something I could get used to but I like the Surefire switch better.
As I recall, the retail price was going to be about $125, but I may be off here.
I liked it and would buy one if I needed a rail mounted light. I think the X200 is a bit nicer, especially for a lefty like me, but the Streamlight is half the price and I could get used to the switch.
