I also have the OP TK11 R2. (I was not aware there was a smooth reflector) this light recently got a very heavy workout when I had to navigate with a team (8 teenage girls & 2 adults) down some extremely difficult features during a night move
. Whilst I had other illumination (Petzl XP Tactica) The TK11 R2 was my only means of making distance illuminated observations :candle: to find a suitable (albeit still challenging) route down and off the feature .
An excellent combo of throw plus flood for a challenging situation.
Any more challenging and I would have spent the night on the hill which may have been an option had I not had a suitable "thrower" with me
I will never venture into the wilderness nowadays without a good "Thrower".
The TK11 R2 is a good compromise in a single cell (Smaller) light :thumbsup:
My Olight M30 is just a tad too big (even with 2x18500) to carry with all my other equipment when backpacking.
I might take my Olight M20 R2 (that I know I am getting for Xmas in the current gift set
) as a replacement for the TK11 R2 but from the quick play I did with it before wifey wrapped it for under the tree I would say they are both in the same league (M20 & TK11).
Using the TK11 R2 as my primary night navigation light and back up SAR, I only replaced the 18650 once during the 8 days I was in the field. Probably about 6 hours total use with at least 3+ hours on high overall. Mostly used for average of 3-4 mins at a time. Second Batt still going strong when I got home. I think short duration high power shots assist with longevity of the Batt (not letting them get too hot?).
To answer the question (sorry I did not mean to give a review) I think the OP reflector is just dandy
