Sunwayman M30R or M60R - XML - anyone have the mah draw for these lights?

I am considering the M30r with Xml, but am discouraged by the low runtimes, compared to the m40c, m40a, etc, but reading a few reviews of the m40a, and m40c, seeing that the runtimes are sometimes significantly longer then the manuf estimates, since the mah draw is much lower and sometimes also brightness is a bit lower on the lower modes. Anyone have any idea on these lights?

Thanks.

Tony

PS. I just ordered an M20C, M30A, and M10A(looking forward to receiving them from Goinggear.com.) These will be my first Sunway lights, as all I currently own are surefires. Hopefully the Sunway lights will be as good as the surefires
