I got a Tiablo A10 yesterday......I'm afraid it still holds the crown of throw king. The reflectors are not the same as rumored. The A10 reflector is about 1/2 mm larger. It will not fit the MPP1 head, but the MPP1 reflector will fit into the A10 housing. The A10 reflector has no weak spot in the middle unlike the MPP1. It also has a whiter emitter than the MPP1. My light meter does indicate higher with the A10, but it is easily thrown off by tint changes. While comparing outdoors there is no discernable difference other than the dark center of the MPP1. During testing I had a UCL lens in the MPP1, and stock glass in the A10. I later put a UCL lens from my A50 into the A10 and got an 11% increase in output. The A10 does however require a bit of focusing as mine was not well focused from the factory. During testing I adjusted the spot size to match the MPP1 spot for comparisons. Overall I like the MPP1 better mostly because I love the grip of the Surefire Z2 host better. The A10 has a horrible tailcap and mushy switch. It also requires two cells to operate at max output, regardless of the fact it says 2.7V-8.5V on the side.I forgot the numbers but it was way off on an 18650. Of course the MPP1 requires two also, but I replaced my driver with a 1.4 Amp 3.7V board. There was very little difference in output. Not sure why, I replaced the board in my Tiablo A9 Aspheric and seen a 22% increase in output with it. The MPP1 will be easily upgradeable with new pills. That is a huge advantage. The A10 is not upgradeable without some major surgery. Can't wait for a pill using the new Cree XM LED. 750 Lumen on 2.0 Amps. And I hope Solarforce will make an 18650 version of the new pills. I hate 16340 batteries rattling around in host that accept 18mm cells. Not to mention the big increase in runtime with 18650's.
