Just received my P10A.
But the P10A produces the exactly the same output on 2AA as it does on 1AA! I didn't want to do a full run like this, since I'm not sure that's safe for the head or batteries.
Selfbuilt - thank you so much for following up on this - interesting results.
I am definitely getting different results to you.
I also did a head swap - to be explicit
P10A head on the 2x AA P10A2 body
P10A2 head on the 1x AA P10A body
and did the following side-by-side comparison beamshots -
Hi level -
seems like very similar levels.
Lo Level -
the P10A2 head on 1x AA Lo level is noticably brighter than the P10A on 2x AA -
kind of corroborating what I saw in Post #
29 with P10A2 head on 1x AA on Lo and "control" comparison of the Fenix LD10 on Medium.
But there is a slight wrinkle -
and
NOT a small one at that......
I'm using my basement which is cold today -
and the P10A2 head on 1x AA was being very temperamental -
there were
LOTS of times when it wouldn't even light up in either Hi or Lo -
I did not see that when I tried it back in Post #
29 (Dec/31/2008).
I doubled checked - changed batteries (freshly charged Kodak Pre-Charged) even changed the tail-switch and the P10A2 head worked fine on 2x AA -
so it was defintely the P10A2 head on 1x AA that was misbehaving.
At least on my one sample the P10A2 head does not seem to want to work consistently on 1x AA today.
If I went by the evidence today -
I would have said this sample of the P10A2 head does not work properly on 1x AA
- so there has to be a difference in circuits between these samples of the P10A and P10A2.
