Streamlight ProTac 1L-1AA:Triple Fuel Flashlight 

Couldn't agree more. Streamlight has superior quality compared to their competition.

I like Nitecore, I'm thinking of this one next

@Avengers: The Investing Initiative I'm 0 for 2 with Olight, and I've tried a few other brands looking for a deal. I just stick with what has worked for me. I made a statement hoping to save a few people the expense of trying a bunch of lights, in support of what Fernando shared. Good luck.

Super Moon I’ve been wondering too. It might work, but with the risk of burning up if used too long. The highest voltage for these lights is 3.2, 14500s, 10440s and rechargeable versions of CR123s are 3.7 volts. What I don’t know is why Streamlight hasn’t upgraded to handle 3.7v.

Can you use the rechargeable c123a 3.7 volts? Or will it burn out flashlight?

WTF....I never seen AAAA 🔋. Thanks for the info. 👍🏻

Just got mine I love the damn thing can’t wait to carry it...... everywhere

14500 works in your rail mount 1 how long have you tested that?

Robert Russo Not sure about actual usage time. I used it for a year on my rifle and now my buddy has it and it's still going strong.

workingclassless84 how big ighter is the 14500 compared to the other battery

Outdoors Man it's definitely a lot brighter than your standard aa battery, but maybe just a little brighter than when you run a cr123. In terms of lumens I couldn't tell you.

I have to agree with this comment 💯percent. I usually blast my streamlights in their highest setting when turning wrenches and not one has fulfilled the posted times for 🔋 life. I keep using because of their durable and reliability but my stinger HL has already killed 3 🔋 's since owning them. Thirsty bastard😆.

@@forgedsteelwrench9249 Dang. I got a Stinger about 11 years ago. Never used it though. What percentage of the advertised life does each of your flashlights last?

I run mine on both types with no issues.

@@livewithnick still no problem? I like the idea but i like the convenience of rechargeables a bit more. Also, the runtimes and outputs changed or are the same as with AA and 123?

FYI, no adapter necessary to switch between batteries.

Use what you like

Ya usaste las recargables 3.7 y si funciona bien

14500

Si, funciona sin problema.

That’s one of the modes you can program. (Tap 10 times and hold on the 10th to switch modes) 1.High/strobe/low 2.High only 3.Low/high

But i holds that amount for few minutes before stepping down and the whole idea is different.

No, not all AA are dual fuel, because you dont use it as is, as you said, you have to stick a magnet. I very much doubt you carry magnets around with you at all times.

@@TheModernSurvivalist - Then you would be wrong, it's on the end of the flashlight.

sounds goofy

@@uuuultra May sound goofy but if it works, then is it really goofy? Besides a moron told me I was having to use a magnet? That's only for the severly underlength batteries. If you want something that will work with 8 or more different batteries, maybe you need a cheap flashlight and a couple magnets. Certainly today, dual fuel is nothing special. Some manufacturers provide O-rings to use under diameter batteries in their flashlights. What is really goofy is throwing away capabilities in a survival situation. My flashlight has a cap magnet, it takes virtually no space to stick another magnet to it so it's always with you.
