From what I can find the LD41 max output is 520 lumens for 2 hours, while the M40a is rated for about 600 lumens for 1 hour, both using 4xaa batteries.
What would account for them having similar brightness, but one having two times longer runtime?
I'm hoping the answer will help me decide between two. Thanks.
