the k40 will have a slightly larger hot spot. that could be a plus or minus to you. i think the slightly larger hot spot will make it more useful. not sure what kind of numbers it will produce, but i would bet it would still be over 400kcd
edit: i would be willing to bet the tn31 is made by Supbeam.
I think Vinh said that it was not the much of a difference of throw. There was some, but he thought that the small size of the K40 was the way to go. He said that he would also pick the K40 over it if it was his choice. Wait a bit, I think there are a few guys who will have both in their hands soon!
Congrats on your monster thrower! Do you know what current sense resistors are being used in Vinhn’s TN31? Was the stock XM-L2 led the one that was dedomed?
Unfortunately I don’t know. This light is second hand, so not sure if it was the original XML2 or not. And if I am hearing correctly, Vinh totally bypasses the resistors. Tom E or Vinh answer that one much better than I can.
Crap your right. Looks like I missed a level. I just tested them again. I stopped at 1050 thinking that was below the highest level. Nope. Level 5 is 1515 and level 6 is 1740. I’ll correct my numbers above. It has THREE power levels over 1000 lumens on an XML based thrower. This light is truly a beast.
That sounds like a beast
I remember when Vihn did initial XM-L2 testing he couldn’t get much more than 4.5A into them, even direct drive. I wonder how he got around it?
