My only AAA light at present is a Streamlight Microstream 1xAAA. It's very versatile since it has both a forward and reverse clip. That's why I bought it. However it has over 2 hour runtime on 800mah nimh so I'm thinking there has to be something brighter out there. The catch is, it has to have a clip.
Then you are pretty much stuck to the ITP A3 which has a reversible clip. It is often sold out nowadays, lightake seems to still have the SS version (q5) and focalprice (R5). The SS version is good when you switch the clip position often. I own the Maratac AAA SS which is similar.
If you intend to clip use it rather than key ring use it then do you really need to stick to 1*AAA? Some AA lights are not that bulky and your choices open up dramatically as most AA lights have clips, all have more run time and you can have far greater output.
Equally worth considering if you will be clip using the light then does it need to be 1*AAA? There are some very decent 2*AAA lights such as the Tank007 E06 that are pen sized (i.e. 12cm / 4.75 inches).
Single AA lights are just a fraction too heavy, as are CR123 and 2 AAA unfortunately. So yes it does limit my options. The 28 lumen Microstream does do the job. I guess I'm a bit spoiled by bigger brighter lights.
The Olight I3 has a screw on clip and can't be reversed. Make sure to get an A3 for baseball-hat- headlamp configuration. I scratched the eloxation on one aluminium A3s of mine which looks kind of nasty. Make sure to get a Maratac AAA SS (if you can find one cheap, they are hard to get) or ITP A3 SS. And if can take the R5 version because the PWM (flickering) is fixed in the XP-G R5 version. I have 2 alu A3 (Q5 and R5) and the Maratac AAA SS. Great lights overall.
I will probably get kicked out of BUDGETlightforums for this, but the IlluminaTi is a really nice light. Its an XP-G R5 emitter and 115 lumens on high. It DOES HAVE a clip, even though the picture does not show it.
Theres a non-titanium budget version, and an S2 bin version that hits 125 lumens.

In this scenario, brightness is more of a battery function than the light itself. Many people use a 10440 lithium ion battery to turbocharge their light. This does exceed safety parameters for the small battery though unless you go IMR, so I would be dubious about it. It also will overheat FAST! But as long as you used turbo in short bursts, this might be an option for you.
