Cypher,
The 8??mA current that I am getting is double the stock bias, what ever that may be. It differs from one unit to the next. I'd say the runtime is roughly cut in half when you go to the 850mA bias. As for performance, I'm thinking that the KL3 at 850mA will kick the 6P's butt in terms of all out throw. Of course, the incand will have a better flood out to medium distances, but in a pitching match, the KL3 will be it.
If you are just looking to clean up the beam, you could just have the KL3 modded with a high dome luxeon and reflector. The high dome will be a higher flux bin than the low dome in there and you will gain output simply by virtue of the bin of the luxeons that I use. Going with the reflector will get you more output because the 27mm reflector is just plain more efficient than the NX05 that you have now. Believe me, leaving the bias at stock and going with the Lux III and reflector will make a nice and day difference. You'll be surprised at the throw you'll get from the KL3, even at the stock bias, which is around 430mA.
My modding thread is here...
Link to mods
If you want to get the mod with just the lux swap and reflector, knock $10 off of the price of the mode. Follow the instructions in the link for the rest of the info.
If you go with the full mod, you'll have a KL3 that will perform on par with any Aleph I or McLux light. Your stock 6P head may very well wind up on BST after you see the modded KL3 in full form.
After having experienced hotrodded LED lights, I don't have any incands any more. Well, I have one, an M3. I run a modded KL2 on that, but keep the stock head and lamps for when I sell it. The incand head never sees service. I've just grown too accustomed to having light that doesn't dim and I can't remember the last time I bought a replacement LA.
