Pöbel, that was an EXCELLENT guess even if calculated. I measured .3lms on low but it didn't matter which battery I used. However, the Med and High outputs were battery dependent. You can check my M11R review for full details if interested.
EDIT: The low level on the M11R is nowhere near the V-series lights I have. Here are shots of the output I took of the three on LiIon's:
L: M11R | M: V10R Ti | R: V10A
As you can see, the V series light didn't even register a reading on their lowest output.
Also, here are three head on shots of each LED using the same exposure (same order as above):
The V10A is the undisputed winner of the "How low can you go" contest.
Cheers,
Tim
