I know, slightly old thread. That happens sometimes when searching around.
Quark usurped my business. I have beein EDC'ing the same Fenix P3D for 2.5 years, since August of 2007. I decided it has been long enough and the technology has advanced sufficiently that it is time to upgrade. (the P1D-Q5 will remain on my keychain)
And it didn't take me long AT ALL to determine that a quark 123^2 Tactical R5 would get the nod.
It is, of course, brighter/more efficient, has a programmable UI, available tactical tailcap for momentary on, LOW low and more. What's not to like?
The 0.2 lumens moonlight mode, for example, will be perfect for traveling, staying with relatives vacation, etc, where my sleeping quarters have less light than I am used to and I generally don't know where things are. Leave it on moonline mode next to my glasses, gun and cell phone....awsome.
And with the clip attached it won't roll all over the often flat/hard surface that it will need to be left on. Hell, I might use it as my new nightstand light as well as EDC. Right now I have two nightstand lights, one really cheap and dim brinkman I've been using for like 4 years and one bright "oh crap what was that!" bump in the night investigation light...currently an Olight M20 R2. But with the Quark I think I could have both in one with nothing but a twist of the head separating which option I want.
So, uh, why would I get the Fenix?
