Hi, I already know their beams because I have seen them on Internet but I'd like to know what is better for their features.
If you know them, can give me some info please? What would you buy?
Thank you!
They do different things.
So far, its like you asked if its better to buy a screw driver or a hammer or a wrench.
The UI on the XT11 wins #1, as its so easy and intuitive, but, its meant for tactical use, and designed to always come on in high, and you dim it down from there if you want it less bright, etc.
The UI on the SC600 is not hard per se, but it is complicated, but does have a memory, and can be set to come on, and change modes to your settings if you have the patience to learn it. I never did, I mostly just use it on high..and, the short cut is you can just hold the on button down, and let it cycle until it hits what you want, and you let go. (H-M-L, H-M-L, etc...)
The twisty UI on the TN12 would be last for me at least, as twisties mean I need two hands to operate the light.
The XT11 is a floody beamed light, the SC600 is a FLOOD light, and the TN12 is mostly throw, and needs to be to compensate for it having the least real lumen output....to get enough lumens out there to see things.
If you want an EDC sized floody beam with throw and use mostly high, the XT11 wins hands down, hence its primary popularity...you can see a lot close up AND far away, all at once, with a great tint and quality of light.
If you want a small, close range flood light, and the ability to come on at a low brightness, the SC600 wins, as that's ITS claim to fame. If you want a warmer version, they also have the SC600W as well.
If you want a weaker light that throws around the same as the XT11, but with less peripheral light, then the TN12 is OK...but its also hampered by short run times compared to the other two.
For me at least, the short run times, dimmer high, twisty UI, and less useful beam, eliminate the TN12 from contention in this contest.
(Its going to have fans of course, its still a good light, but, the competition above is too fierce. )
