Wow !


What a great review !


Thank you to everybody for all this Great Information.

soyou could get a p10a2 and use a 1aa body but not vice versa.
good research

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.

Interesting Vincent ... we clearly have different P10A heads, because mine will not do anywhere close to the max output of the P10A2 on 2AA.

I'm about the leave on holiday, but here are some detailed output numbers in my lightbox (all on eneloops)

P10A2 Hi 2xAA = 79
P10A2 Lo 2xAA = 35

P10A2 Hi 1xAA = 57
P10A2 Lo 1xAA = 36

P10A Hi 2xAA = 57
P10A Lo 2xAA = 21

P10A Hi 1xAA = 58
P10A Lo 1xAA = 22

As you can see, my P10A head has exactly the same output on Lo or Hi on both 2xAA and 1xAA.

In contrast, the P10A2 maintains the same output on Lo (which, like yours, is higher than the P10A on Lo), but has different outputs on Hi in 1xAA or 2xAA format.

I wonder what kind of runtime I would get on the P10A on 2xAA, since output is unaltered compared to 1xAA ... but I don't plan to test this, since it may not be safe for the light (or batteries).

P10A2 Hi 1xAA = 57
.............
P10A Hi 2xAA = 57

Hmmmm... perhaps our results may not be differing afterall -
P10A on 2x AA Hi and the P10A2 on 1 xAA Hi looked to be about the same level in the comparison beamshots in Post #43 .....
but the problem with comparsion beamshots is that they just compare and do not measure - so we don't know if they are both 220 lumens or 20 lumens.......

So I compared the P10A on 2x AA with the Fenix PD30 (2xCR123 Q5 rated at 220 lumens)

this shows the Fenix PD30 is brighter than the P10A on 2x AA
(in EagleTac P10A2 Comparison Review the P10A2 seemed on par with the Fenix PD30) -
so this shows the P10A on 2x AA is not as bright as the P10A2.

But it still looks reasonably bright - so how bright is it?
vs. NiteCore D10 (Q5) on 3.7V rechargeable Li-Ion 14500

looks about the same ballpark -
and the Guesstimate was my sample of the D10 on 14500 may be around 190 lumens, as that combo essentially matched the NiteCore Extreme see post #44 in NiteCore D10 Comparison Review

So this means that the P10A on 2x AA is brighter than the P10A on a single AA.

P10A2 Lo 1xAA = 36
.......
P10A Lo 2xAA = 21

This also seems to corrobate the brighter Lo level of the P10A2 on 1x AA in the second set of beamshots in Post #43.

Re: EagleTac P10A tint?

I was hoping to buy a P10A in neutral white to go with my P20A2 in neutral white. Was the P10A, like the P20A2, even offered in a choice of tints? If not, how would you describe the tint. According to this review, it's neutral-white. But I find it hard to believe that no one else would mention it.

Suggest asking that reviewer whether the light tested was a Neutral White emitter - or if they were just using the "neutral" colloquially to describe a lack of obvious tint.

The light(s) I reviewed are the basic Cool White emitter(s) - there are 34 comparison beamshots in this thread alone - so hopefully one can judge for oneself?
