Surefire M600P vs. M600U

[Beat Trash]

I was wondering if anyone had experience with both of the above weaponlights, and could offer any insight on differences in throw/spill. I searched and could not find much about the P model in particular.

I am currently between the two as a light for a 14.5 BCM KMR ELW with a H1 2moa micro. Both lights have 500 or so lumens. I know the U model will have greater throw and the P will have greater spill. I am wondering how far out the P will still effectively throw vs. the U model for the purpose of target ID and detail such as hands. Projected distance for the use of this upper at night is between 20 to 60 yards, occasionally maybe out to 80. As light as this upper is, the 2oz weight increase of the P is not really an issue.

I have a 3 cell Fury, but that is around 1k lumens I believe, so I cannot really judge the Fury head performance by the output of that light. I have a X300u I can try, but I think that uses a larger reflector than the 600u. For this rifle, the X300 is not an option. The P is a bit cheaper, but I do not mind spending a bit extra to get the desired performance.

I appreciate any assistance with this comparison.

I am using the same gun as you mention, just with a T-1 as an optic. I went with a Surefire M300c in an Arisaka mount. This is my Patrol Rifle for work. I found the throw of he 300 lum was sufficient for me needs. I wanted to keep the size and weight down with the accessories mounted on this upper. I like it so much that I set up an exact spare gun to be kept at home for my wife. It was the only way I could keep her from appropriating my Patrol Rifle once she shot it.

My guns run the 600u my brother has the 600p on one of his.

Between the two the flood is noticeably wider and does not have the focused hot spot in the middle like the ultra which I'd say is an appreciable difference indoors. Outdoors the throw of fury compared to ultra is maybe 40% less (rough estimate on my part) but that said at the distances you mention its a non issue. There us still plenty of light to ID at that range IMO.

Lastly from what I've read the fury does not use the same TIR lense as the scout ultra so that is where some of the cost difference comes from.

Any chance you and brother can take some pictures indoors? Let's say a garage or basement? I'm in between choices too, but could benefit with tape switch due to multiple spots indoor that need to switch off/weak hand.
Thanks
