Sneakers's one is rated at 220 lumens. This one is 200 but mil. Comes with a QD low profile mount, strobe and a pressure switch. This is the one I have on my gun.
I read an interesting article on a police site that was like 'don't use too many lumens if you're indoors or close range, or the reflected light will fuck you up', which I experienced first hand at Hoki. Especially with the lads trying to light doorways from 20 meters back and doing nothing but blind and illum' the friendlies stacked up beside it.
