haha. i this it is little more similar than both having an on/off switch and different modes, the button to change modes is also hold to strobe etc. but you have pointed out many important differences.
i now have the m20x. it is quite floody. in my inexperienced opinion, it certainly isn't much of a spotlight which i guess is more practical for most people.. the beam still reaches a good distance but there is no spot real spot involved, (3 trees will light up, rather than just a super-bright branch) what % of people really need good light on stuff over 150-200m away? i would guess less than 50%, not me anyway. would've been fun though.
it is fantastically bright, has a nice transition from spot to spill, and is feels well made. got it got $140 delivered with red filter, ATP Ti A3 AAA keychain light, weapon mount, 2x 18650 protected cells and a quality charger, holster, remote switch. very good deal.
CONS:
- the side switch blends in well with the barrel and is a pain in the *** to find in the dark. people say you can line up the belt clip with the button but the belt clip has a special indent to sit in a particular spot... unless you stop screwing the tailcap when the button lines up. either way - not ideal.
- the holster is strictly built for belt use. it won't work well as a cover in your bag as the torch moves around a lot and the barrel can fall out quite a bit, won't protect from dirt, and there is a strange hole in the holster so you can turn it on and use it while its in the cover, a little pointless but hey. i don't like velcro either. but that's just me. maybe you love it.
- it comes with a great GITD tail switch, but it took me 20minutes to put on and it still isn't perfect. - make sure you really want to use it before removing the black one.
Overall it's great. For a light that small, it is very, very bright. And sufficiently floody for amost anything in my opinion. Unless you're reading maps all night.
Good difference between modes and you never need to see strobe unless you want to. I've noticed the beam floods more if you take the strike bezel off too. Good purchase, would like to compare it to the XT11. I think the UI would be easier. Dam that side switch isn't easy to find.
