So my P2D R100 arrived today, cheers to Lighthound for helpful service and fast shipping; I placed my over-the-phone two-credit-card order on Thursday, they said they'd ship my order out on Monday. And my order arrived ...Monday. Faster than advertised processing/shipping is always a pleasant surprise :thumbsup:
I've done some various indoor/outdoor testing and comparing, and the quality of the light is just as the reviews say; notably warmer than the Cree with a much smoother beam profile. My beam corona has some very faint wispy edges to it, but you don't notice it unless you rotate the light against a white wall, certainly nothing on the order of the Cree donut.
Color rendering is a bit better than the Cree. The Rebel isn't quite as red-phobic, and though blues and yellow-greens still slightly fluoresce, it's not as pronounced. The overall light characteristics of the Rebel, with its near-white tint and "pretty good" rendering, reminds me very much of a good quality CFL bulb.
Comparing the P2D R100 against a P1D Q5 outdoors, the spill is almost exactly the same size, the throw is identical, and overall both are very well matched. I can see why Fenix used both of these emitters, as they perform so similarly in almost every respect. Again, the one big difference is tint; the Cree's otherworldly super-cold tint seems out of place outdoors, while the Rebel's nearly incandescent hue seems much more natural. Now that I've compared both side-by-side, I think I'd prefer the Rebel for camping/walking use, while the Cree is better suited for indoor and urban situations.
As a longtime P1 user, I definitely dig the interface and appreciate the pushbutton operation. Being able to go instantly from turbo to low and back again is a big plus in my book, though when it comes to cycling through the levels, or starting on a lower level, this P2 has *pronounced* instaflash. Not a big deal since the P1s do the same thing, but it's more startling when you see it starting from the low setting. A quick 175 to 10 lumens in a dark room looks like a small explosion, so this still isn't the perfect nightstand light. Switch-wise, I agree with those waiting for a forward clicky, but as reverse clickys go, this one's nice and solid.
Overall the P2D R100 is a winner, easily on par with the Q5 competition despite having a wholly different tone. If you use your current light outdoors frequently, it's definitely worth a try :twothumbs
