Can someone comment on differences between the TK16 and TK22

I can read the specs, of course. Most notably, the TK16 puts out more lumens. How does that translate into actual use? What are the differences in the beams?

Is there any real differences in the way you would use them?

Advantages? Disadvantages?

Thanks very much.

You wouldn't even notice the 80 lumen difference. The main differences are the head size, 34mm vs 40mm, which means the TK22 will throw farther. And the U.I., the TK16 has a dual switch tailcap, and the TK22's mode switch is right below the head. The TK16 is better suited for overhand carry, the TK22 underhand carry. At lest for me, I can't change the modes on the TK22 without flipping it over in my hand. The beam on the TK22 is very smooth due to the OP reflector I can't comment on the beam of the TK16 because I don't have one.
