It's about the same dimensions as the 4Sevens Maelstrom X7 which I used to carry. I prefer to pocket carry and the X7 was just a little too large for me to do so comfortably on an every day basis. In a holster it was just fine.
Now a Surefire C2 is about the largest I carry on a routine basis. Just like StriderSMF, I carry mine clipped inside my front left pocket.
I regularly carry the Nitecore P25, Eagletac G25C2 Mk II with flip-up diffuser, and the Klarus RS11 (though not all at the same time ). Have EDCed the Nitecore TM26 a few times, but not part of my regular rotation (overkill for daily needs). If you have a good holster, the size isn't really much of an issue. In fact, the only light I have that I haven't ever EDCed is my Fenix TK75.
If I know for sure I'm going to be out in the dark and will need a light, I'll carry something larger than your typical EDC format light. As far as a light in my pocket or on a neck lanyard, no bigger than 120mm length and 25 mm head. My V10 or V11R with AA extender are always on me.
Eagletac D25A2 Clicky is the biggest I would comfortably pocket carry, regular days biggest is any single AA or single CR123 size lights. I have a sx25a6 in my bag.
My biggest EDC light is a tie between my ZL SC60 and SF E1B. I dislike having things on my belt, and anything bigger than ~4.5"x1" get's annoying for pocket carry.
I usually have a 9P or C3 with me, often both, plus a 6P. I also keep a SF E2 (though it isn't very big) in a holster on my backpack, just in case I get caught out without any of the three lights mentioned above. None of the above are typically carried in pockets.
Most days, I clip a Malkoff MD2 bezel down into a front pocket comfortably. Occasionally I'll replace it with a Surefire C2, or VME-d E2L the few times I need to go smaller.
I carry my nitecore p25 on my jeans hip when I need it, mainly for the early hours of the morning till the sun rises.
I don't wear a belt so I use the clip and fix it to my work pants. Works fine for me as an EDC. And it's USB rechargeable which is convenient.
My EDC is a Fenix E01 in Purple. It rides on a 'biner with my keys and my Spyderco Ladybug3 in ZDP. If I'm going out at night or in the late afternoon I generally take my Surefire E1B along with me, too.
