I know that I linked to the Surefire 6PX-Pro not to long ago, but I just found this model when I needed a second Surefire — and man is it great. It’s a dual stage LED that outputs 15 lumens on the low end and 500 lumens on the high end (the aforementioned 6PX-Pro tops out at 200 lumens).
It’s really bright — like amazingly so.
It is just a touch bigger than the 6PX and yet it is over twice as much the output. Really amazing.
