Hello everyone ... first post here on the forum, however, I have been following for about a year.



So, my issue: I have two Nitecore D11s (both XP-G R5 models) that seemingly are different flashlights.



Differences:

- One is black and one is dark gray;

- One has a red circuit board the other has a green one.

- The D11 with the green circuit board (gray unit) seems more flood like and the beam seemingly is less focused that the D11 with the red circuit board (black unit).

- The piston on the black (red circuit board) unit is much easier to push.

- The black unit is still in the box and not used.



Both units were purchased from goinggear.com in October 2010; both units are using fully charged Sanyo Eneloop AA batteries; the UI on both units is the same. So why the performance differences? I understand there will be some fluctuation with these units but should there be so much of a variation? Does using one more often decrease its performance?



Thanks for your opinions in advance.
