I just took the k40mvn out for a spin last night.
The amount of flood is huge, and it can out all that light down range pretty well with the deep smooth reflector.
I'm very impressed.
The x40vn is going to be a much tighter, more throwy beam, while the k40mvn is going to have an immensely wide beam, but can still throw it pretty well . Of course not as much, but currently, I have no mtg2 that will throw this far.
Having the 6 modes is great too. At 4 it's getting painful indoors, and when you reach 6 it's just incredible.
When performing a cieling bounce, It's just as bright as my tk75vnkt, and Shockervn, both dedomed around 4000lm . The k40mvn was supposed to come dedomed, but didn't. After testing my first dome on mtg2, I can say even though I love warm tint, the crazy brightness of the mtg2 with dome, is hard to argue.
I compared it to my other single mtg2 mx25l3vn and performance wise it crushes it completely. I personally love the mx25l3vn, but in terms of output, the k40mvn just has the muscle.
Compared to my tk75vnkt (pretty close to the x40vn.... Sorta
) the size of the hotspot was the immediate difference. The tk75vnkt was tight and very intense.
The k40mvn was huge, and even being so much bigger hotspot, was just as intense.
Taken outside, it was blanketing both sides of my street with very bright light, while the tk75vnkt shot right up the middle, and kept on going of course. Both lights reached everything in my test, so I can't really call just how well the k40mvn throws.
For general purpose, and situations where you need a huge area illuminated, at a good distance ( to be determined after more testing)this is the light you want to bring.
