Who knows with Surefire...I ordered my L4 when they first came out and it took forever...months...They are so tied up with military contracts that generally the regular consumer waits longer.
SF customer service told me yesterday the helmet light will be available by the
end of March or mid-April but the Kroma won't be available until end of this year
Out of curiosity I just called SureFire up to see what I could find out. In summary it seems that the answer I got from them is pretty much consistent with what Seery previously posted.
I admit that I would prefer my K2 Kroma sooner than later. But in the end, I know that the quality will be worth the wait.
