I have bought three EDC lights in the past month.
They are:
1) Quark Tactical 123*2 XP-G R5 (OP reflector)
2) Fenix PD30 123*2 CREE XP-G R4 (SMO reflector)
3) EagleTac P20C2 MkII 123*2 (OP reflector)
The Fenix PD30 is small, perfect for EDC. But the Quark is the same size, and noticeably brighter. The Fenix lumen rating is higher, but rated at emitter, while the Quark lumen rating is OTF (out the front). The light coming out of the Quark is definitely brighter than the Fenix to my eye.
I totally love the Quark's UI. The forward-clicky Quark is the only one (of these three) that allows me to have a hi-power tactical strobe available in the first press (which can be momentary). You can program ANY two options on the Quark for immediate access, one of which will be available when head is tight, the other when head is loose. To me, this is the absolute best UI. But hey, everyone's different, so pick and choose the UI carefully depending on your wants and needs.
The EagleTac slightly outshines the Quark for sheer lumens-power, but the EagleTac is a little bit bigger than the Quark. Plus, the EagleTac (like the Fenix) requires two presses to get a tactical strobe. In a high-stress self-defense situation, I do not want to have to remember two presses, I will be too busy worrying about surviving - I simply want to hit the switch and have tactical strobe immediately available. But of course, this may be of no concern to you.
My vote goes to the
Quark Tactical 123*2 XP-G R5 as the best EDC light of the three. It's bright, lightweight, fits in pocket real easy and has a great UI, with tactical strobe immediately accessible.
My next choice would be the
EagleTac P20C2 MkII. It has the most lumens of the three, no doubt.
My last choice would be the
Fenix PD30. The SMO (smooth) reflector makes the spot too focused.
The main reason I went for the Quark Tactical 123*2 version, is because I want something that slips into my pocket very easily. If you buy the CR123 batteries in bulk, they are fairly cheap.
