Designed as a weapon light, a twist bezel w/2 modes seems apropos. Other than now offering an XM-L emitter, I wouldn't compare it to the PD35.
Two different lights entirely.
+1! The PD35 and the T100C2 MkII are not really comparable lights. True they both are 2xCR123/1x18650 but if we really want to find a close Fenix equivalent to the T100C2 it would probably be the TK11.
The difference is Eagletac update their older models with newer LEDs while the TK11 has had the same old and underdriven XP-GR5 since the March 2010! I assume Eagletac do that because their older models keep selling well.
Fenix seem to focus more on new products and discontinue older models or no longer update them until they phase them out.
And twisting to switch modes isn't that handy with bigger lights.
It depends what you look for the UI. In fact twisty offer several advantages:
- they can be operated with any kind of gloves;
- the head is in one place and, unlike side switches, does not need to be located;
- if the threads are properly lubed the head can easily be twisted one-handed and without changing grip;
- they allow selecting the output while the light is off.
Definitely not the best UI if you are looking for several brightness levels and expect to change output very often but otherwise I find it to be very practical.
