That wiseled looks nice, but 780 bucks!?! Holy crap man. I guess if you are rich or have a legitimate and important use for that kind of power, go for it.
I am not so sure about that ultrafire. I think the Trustfire will throw better and it is 50 bucks. The ultrafire uses a SST-50, so the best case is going to be around 800 lumens, even at 3 amps. Probably a lot less.
The Trustfire uses 5 smaller emitters that are known for having good throw. As such, it can drive them within their range of efficiency for a better overall output. There are multiple reviews and beamshots of the Trustfire around.
In any case, neither Trustfire nor WF will hit close to 2000 lumens. I mentioned the trustfire because it is probably 800 real lumens and super cheap with great throw.
But if you really want high power, you will need to step up to the XTAR or Olight.
