Monocrom please get back to me when you awaken!
Well, considering your requirements; there are a few good choices indeed.
I
don't recommend the T1. The TK10 has the same emitter, same output as the T1. (225 lumens out the front, if you use Surefire CR123 cells). That's impressive. But the TK10 is an improved version of the T1. Better tailcap, improved clip, better checkering. Go with the TK10 instead, if you want a T1.
Avoid the LED Scorpion. I have a Streamlight LED TL-2, 2nd Gen. model. Same emitter and output as the LED Scorpion. But both lights are only rated at 47 lumens. And those are emitter lumens, so the light isn't even that bright. Don't get me wrong, the output is very good, but it's an older light. Although a proven design, the TK10 will blow it out of the water, in terms of output.
And I actually own the Streamlight NF-2 Xenon model. It is possibly the worst designed flashlight I have ever seen. The hard plastic grip-ring seems to have been designed for some sort of alien from outer space. It's way too big, way too uncomfortable. And the tailcap switch makes no sense. A flush tailcap on a light with a grip-ring is like putting ice cream as a topping, inside of a roast beef sandwich. While trying to adjust the ring, I lost the tiny nut that helps hold the ring in place. So, I tossed the ring in the trash. Without it, the NF-2 is actually a very handy light with good output. Small and light weight.
I've never ordered from Pacific Tactical Solutions, but the site has an excellent reputation on CPF.
Another option would be the Sniper model from Wolf-Eyes. Designed to fit the same role as a Surefire 6P. And it can run on one 18650 or two CR123 cells. (The other lights mentioned are not rated for use with rechargeable cells. I've heard that the TK10 can run on two RCR123 cells. But can't confirm if anyone has run those rechargeable cells successfully in the TK10). The tailcap switch is a bit soft. But other than that, a good light that is available in both xenon and Cree versions. Good bang for the buck.
