How does the Inova x1 compare to the low setting on the L1T. I've heard people saying the L1T is too bright on low and that they can't really see much of a difference between the two. Isn't it 10 lumens low and 37 lumens high? That seems like it would be quite a large and perceivable difference. Just wondering b/c I already own a x1 and have been looking into getting the L1T and would like some information about it that I can relate to something I can directly compare it to.
