Brightest light that will fit in a Maxpedition M2?

[bigmikey]

What is the brightest light using single AA's, or 2AA's About the size of a minimag, or inva X1 size, that will fit in a Maxpedition M2 waist pack?, I was looking at the Inova X1, but dont know the lumens it has or how far the throw is, but that is one I am considering. Please give me your opinions which is the brightest single AA with the farthest throw. Thanks in advance..

If two AAs, you should look at Lambdas Illuminators...
