I know this reply is months late but I thought to post it in case others run across this thread like I did.
I run the Fenix TK11 and have used it as my primary tac light, weapon light, and all around flashlight for a few years. It's been dropped from over 20 feet up onto a concrete warehouse floor, soaked in rain and mud, tossed around in gear bags, etc.
It kicks butt! If I had to choose a single word to describe it, that word would be QUALITY.
Very bright, good on batteries, and extremely durable. Another plus is that although it uses the 123 batteries, one can also purchase the 18650 rechargeable battery and the charger. They last so long that I end up swapping them out just to keep a good rotation on the batteries going.
