I've been EDCing one for about 2 months, and I second what AV says. Tint on mine seems perfectly white, but I'm not too picky about tint unless it's really green, blue or yellow. It has PWM on low, but that doesn't bother me since I usually don't look at rotating objects. I've ordered a Microstream clip so I can use it as a headlamp if I need to. The ten-tap programming is nice, you aren't stuck with one UI. I've programmed mine low-high. The only thing I think I would change is the mode switching, I prefer a "click on, click off, click again to advance." It uses a "half press from off" to advance (forward clicky) like other Protac series lights. Again this is not a big deal, I've never found the perfect EDC, but this is as close as I've found. It's built like a tank, very small so it fits easily in my pocket, and has adequate output (70 lumens may not impress some, but meets 99% of my EDC needs). With a Eneloop Pro, I get an honest 1.5 hours before significant output drop on high.
Just to show what competition it's up against, lights I've EDCed in the past are NovaTac 120E, SureFire Stratus, 6PX, G2X, G2 and 6P w/incan and Malkoff M61LL, E2E w/ Veleno drop-in, V11R (2 different lights), Stylus, Stylus Pro, Quark QTA Gen 2 (2 different lights), Preon Penlight, Minimag incan, Maglight XL50, Peak Eiger Lug SS #8 Medium (non-QTC, still carry that on my keyring) and several E1Bs (my second favorite light). There are other obscure lights going back to 1975 when I started carrying an EDC, and I pretty much liked them all for various reasons, but hands down the Protac 1AAA is my favorite so far. But remember, YMMV.
