Nothing better to date, and maybe for years, and years! And, we don't want powerful!Not very powerful, though, looks high quality!

La Petite Killer, the one, the only and best ever button cell light in history. Made by a master machinist. There are many, however, this IS it, and that's that!
Oh in Titanium!
I have three, must in case...

....I mean, if a single AAA can be 120 lumens, why can't a stacked button batteries get that high?

I'm bringing up the topic of powerful. Is there a key chain sized button cell light with an amplifier out there with power? The Bright Shine may be but I didn't hear the video say 70 lumens, and I haven't found FL1 specs for it legit yet. I suppose I don't mean to hold back the momentum of the post if the OP had a goal of simply mentioning lights that are recognized, but I'd like to see a high performance LED use an amplifier to reduce volts and boost amperage to get a nice high lumen count. I mean, if a single AAA can be 120 lumens, why can't a stacked button batteries get that high?
I don't think it is worth a new post, but are there any AAAA battery run flashlights out there? They would be fun to have and use, as they would be in between AAA and button cells.

About LR44
LR44 is an alkaline 1.5 V battery. The most common equivalent batteries are:
Silver Oxide Equivalent Batteries
- AG13
- L1154
- LR1154
- 157
LR44 can be also be replaced with a silver oxide battery. The most common silver oxide equivalents are:
- SR44
- SR44SW
- 303
- 357
Short answer is that the high internal resistance limits sustained current draw.
Thing is, to get 120 lumens 2015 technology allows about 1.0 even perhaps 0.8 volts, so according to your numbers, it would only take 6 LR44 batteries to match it in amps. Then we can talk about how 6x150 mah of energy total is way more than a 600 mah AAA, meaning the bat life would outlast a typical AAA. If above comment saying you can get LR44 batteries for 8¢ on eBay shipped, then you have an equivalent to AAA light, in all aspects, accept one-use the LR44 flashlight would last %30 longer. So,, there's your math.
I didn't think LR44 could even DO that... Even 3 in series with 2 stacks parallel. Don't they choke at something like 50 milliamps individually?Well ... it should be pretty easy to discharge test a AAA vs a stack of 6x LR44, for capacity ... at what was the current draw you were wanting ? An amp (1000 mA) ?
:shakehead

Man.. That thing is absolutely incredible. If it werent for the price tag on one of them id be all over it. I really love how that lamp looks.

NiMH AAAx1 Eneloop can draw a bit more than 300 milliamps, afaik.Amplifier. Amplifiers do what they sound like they increase amperage and drop voltage.There is no way one AAA completely outperforms 6-8 single batteries in an unreachable way, the energy density just isn't there.
