I think there are some issues with the first batch of Avengers, according to the reviews and marketplace threads. At the $4x.xx price range, I'd go for the Fenix L0D Q4 (75 lumens) from Fenix-Store

I think alkalines will never be able to provide enough constant juice to power these high powered LEDs. I would go with a simple and reputable light like the LM31 from BatteryJunction for AA battery.
+1 on the
L0D Q4 seasonal special at the Fenix-Store.
I'm not as big a fan of the LM31. It has a really complicated two level clicky switch that has caused problems.

If lights are bad right out of the gate like this, it doesn't give me a warm fuzzy feeling about the long term reliability.
Also at least one person reported a runaround from their Lumapower dealer about having to return the light with 'all original packaging' just to get warrantee service. Who the hell keeps all that stuff? Of course this kind of garbage becomes just a 'big misunderstanding' when someone posts a complaint and the dealer starts to sweat lost sales, but what happens in a few years if LOTS of them start to fail, and the dealer starts to use these cop-outs with everyone?
Getting back to the L0D-Q4, you can read my Kudos thread to find out how folks like this light -
(100% positive on build quality and brightness).

Don't be fooled on the Tiablo A1 and Lumapower Avenger because they seem to be using specs that are total BullS#%T.
Personally I would prefer not to deal with a company that would lie as badly as both Lumapower and Tiablo are on these lights.
In the above thread I did calculations which prove that the L0D-Q4 is
brighter than a 100W work light at the same distance, and unlike most of the 'Avenger' and 'Tiablo' info that's
NOT B.S.
Here is a nice image that sums up the performance of the L0D-Q4 -
But surely this is an unfair comparison!!! What about runtime?
The output from the big incandescent Maglight starts to dim right off the bat when you first turn it on and hits the 50% level in only a little over an hour.
The really amazing thing is that the L0D-Q4 not only puts out more total light than Mag 4 D-Cell light, but will actually exceed the runtime to 50% brightness when run on on a single tiny L92 lithium cell, which will power the light even on max for over an hour and 20 minutes.
In fairness to that good ol 4 D-Cell Mag incandescent, it was designed for more throw with that huge reflector, and it will limp along getting dimmer and dimmer for maybe 10 or 12 hours before completely winking out on the runtime test, but in a keychain light you want a slightly floodier beam anyway, and the L0D has a nice low mode that will run up to about 9 hours on a L92 lithium cell, so if you need long runtimes, they are available, and unlike the Maglight that low mode is there when
you want it, with that incredible high mode only a quick twist away.
How many people can honestly say their keychain light outperforms a 4 D Maglight on both runtime and overall output?
NOTE:
Since I have criticized Lumapower and Tiablo for their TOTAL B.S. specs on their AAA lights, in the interest of 100% accuracy, I should point out that the Red L0D-Q4 was NOT rated by flashlightreviews.com only the standard L0D-CE WAS.
In their
review of the original standard L0D-CE flashlightreviews.com says -
"The shear volume of light produced is amazing for a single AAA cell light. My readings show that on the "high" setting the L0D-CE is producing more light overall than a 3-D Maglite. On "medium" it produces more light overall than a common 2-D cell light. All this from one AAA cell."
That statement was for the
original L0D-CE, the statement about the Q4 version was extrapolated by me based on my experience and measurements.
Specifically flashlightreviews.com rated the original (50 Lumen) L0D-CE as having an overall output of 3380 on his relative scale, while on the same scale the
4 D-Cell Maglight was actually measured only slightly higher at 3800, based on this I would expect the L0D-Q4 (75 Lumens) to rate about
5070 if it was measured in the same way. Obviously this will simply blow away the good ol 4 D-Cell Mag incandescent.
In any case, I don't think there is any doubt that, unlike Lumapower and Tiablo, the above Fenix L0D-Q4 numbers are conservative.
Side by side, some have reported that the Tiablo is very slightly brighter in the hotspot, but this is only because it has a
smaller much less useful hotspot. Total output seems to be
LESS (from a light with the B.S. rating of 100 plus lumens!)
The avenger is also no brighter and is a new light with an unproven track record at this point.
Here's a quote from one new 'Avenger' buyer -
"I got mine today and I must have received a bum unit. It had some intermittent problems where the low would not activate or I would tighten it and it would turn off from high but tighten it a bit further and it would turn on again."
Unlike the L0D-Q4, the Tiablo A1 also does
not have a long runtime mode (handy if you get stuck for several hours in a power failure).
Some have also received Tiablo A1 lights with crap behind the lens, so you are getting DX quality at Fenix prices.
Bottom line is that the Fenix L0D-Q4 is a MUCH safer choice for a gift (and comes in a really nice gift box, at no extra cost).
