I'd like to add a few things, if I may.
I don't own the MC, but I have read, more than once, where someone ran the MC w/ WA 1160 constant on and it melted something or other: reflector or bulb pedestal or both. The MC was definitely NOT designed to run that hot and at that current! If you can get your hands on the PMR for the MC (Perfect Mag Reflector - specially made Carley reflector for a group CPF buy, now closed) then that might solve or at least help the problem.
Now the TL can run an entire battery discharge with no problems, just like the SF lights. Yes, the TL will get definitely warm, but nothing to concern you. I often need to run my high power incans for 30-45 minutes at a time, or longer, so I would not get the MC unless I could solve the over heating issue.
As for the TL vs. US or MC, I have never owned either the US or MC, but what I can say is that the TL is AWESOME! I love it. It is a VERY well built, simple, bomb proof light. It is HA type III, so it does not scratch very easily and will look good for at least a decade of normal use, vs. the normal type II which seems to look like dog meat after a few months. It has gold contacts inside and a rear mounted switch and the beam has a nice combination of focused hot spot/good throw, and good useable spill light. And, the company is really great to deal with and stands behind their lights. Go for the TL! You won't go wrong!
Also, you didn't hear it from me, but certain of us incan. boys are scheming up an equivalent WA bulb upgrade for the TL. How's 500 lumens sound? Run time to be determined, and will have to be a bulb/reflector combo assembly. TL may soon be on top again . . .
What? Did someone say something? OK . . . moving on . . . nothing to see here. These aren't the droids you're looking for.
