Hello Mactrix and welcome to CPF
The poll is not objective.
All depends on your tasks. The beams of the mentioned lights are all different.
Also the discussions of brightness.
No question, the new Led's (Cree/SSC) are more efficient but they must not be brighter than a LuxeonV, because it depends on the driving current.
The used Cree's in the lights which are available today are not as bright as a LuxV W-bin's, driven at specs, that's my experiences. Perhaps that's subjective because I can't measure the Lumens output, but for my eyes and the eyes of friends of mine.
Also there is a big difference in overall brightness and Throw. I have build a light with an Aspherical lens, which is very bright in the hotspot (used a Cree and its brighter than a Fenix P1D-CE due to the higher driving level). It throws easily 100m, but the overall output is weaker than my LuxV lights.
The SSC's, driven at about 1,2A are about the same brightness, but which stock light drives the Led so hard?
No Lumapower, Lumahunter........
So at the end, each light is its own package which individual tasks. My Fenix P1D-CE is a nice light, but build for other tasks than my LuxV lights.
When you like the U2, buy it, it will fullfil its tasks.
Also the Fenix lights or other brands, they are build for different tasks.
Best regards
