    That's exactly why he can use Li ion without a problem.



    Those are not for the average Joe. You have to understand the ins and outs and do your own research before using them.

    Don't worry, it's not like playing with radioactive stuff but they still require some precautions because they are POTENTIALLY dangerous.

    And yes, you need a dedicated charger and no, they won't fit in every flashlights.



    You better stick with AA (LSD rechargeable like Eneloop) for now.

    Just ordered a Jetbeam Raptor after doing some looking around. I couldn't resist the 550 lumen output with a CR123A.:eek1
    Should work out just fine. I'll post up my review if anyone is interested.

    That's a lot of bang for the buck. 900 lumens from a $15.00 light!

    right... theres two general numbers everyone is familiar with on batteries.. voltage, and mAh. mAh is milliamp HOURS... which is a measurement of energy storage(capacity) over time, not the amount of power (amps) a battery can deliver at once.


    Theres another rating that most people dont get or see on batteries... its the discharge rate. an example would be that A123 LiFePO4 cells only hold a capacity of around 2300mah at 3.3v, but they have a DISCHARGE RATE of 70Amps nominal, and 120A peak.

    http://www.espritmodel.com/a123-2300mah-cells-lifepo4.aspx

    as a good example, you could take 4 of these little cells, wire them up, and use them as a starter battery for the average bike. (my KTM 450 Supermoto would pull about 70-90 amps).

    (note: don't confuse the A123 cells i used as an example with CR123 cells)


    Now.... on all of these flashlights, the LED's are driven by smart circuits. Most will handle a narrow voltage range (anywhere from 1 or 2 volts range, to 5 or 10v or more). Because of the design of the LED, the driver circuit also limits the AMPERAGE going to the LED... some can handle a few hundred milliwats, some can handle 2 or 3 AMPS or more. the more the amps, the brighter the LED (mostly). Also, the more efficient the LED, the cooler it runs for the light it outputs.

    You still need to look for flashlight circuit specs.

    Just ordered the Xeno 03 because of this thread. I just bought a 3 LED flashlight pack from Sams, guess I could give those away :D

    I've always liked flashlights, ever since I was 3 years old. I always asked for a new flashlight for Christmas or my birthday. I haven't been much of a flashlight person since I grew up. Hopefully this won't become an obsession now that I ordered (what looks to be) a high quality flashlight.

    If you over discharge a 18650 Li Ion it they almost always short internally and fail. If it does come back the life and capacity are very much shortened.

    If you overcharge an 18650 it will also fail, and can even catch fire in extreme cases. It takes special charger and protection circuits to be safe.

    It has more energy than a common firecracker (not M80 or cherry bomb, just your common 1 1/2 inch), you do not let those go off in your hand, well, not more than once.

    If you know what you are doing, they are great, they are not for everyone.

    A123 does not have all these problems, they also have less energy.

    It's why protected cells exist though.

    Delivered today.

    Nice piece of work. Drowns out my old el-cheapo 9 LED 3 AAA hardware store lights on its lowest setting. Great output! My only complaint is the adjuster ring is a bit too easy to turn and will probably self-adjust in my pocket. Should have detents.

    I saw a review and it was stated that the CR123A>AA adapter was an extra bit that needed to be ordered separately. Came with my order along with spare O-rings, lanyard, pocket clip, and a switch boot.

    I ordered from Battery Junction for the only reason being that they are close by and didn't shop around a lot so there may be better deals to be had but they did send me a coupon code for 5% off of my next purchase. Not sure if it's specific to me and how many times it can be used but if anyone wants it PM me. I'll post it if that's not against the rules....:dunno Don't want to piss anyone off. I'll never use it. Got a dozen CR123A's with my order and fully expect them to last me a long time.

    So I finally lost that tiny Streamlight I started this thread about! The thing about tiny things seems that they are easy to loose. Anyhow, I have been on the lookout for a birghter replacement for it ever since I lost it a couple months ago. I was doing an install yesterday and could have REALLY used that little light so got stoked to just go to Sportsmans and have a root round for a replacement. I found what I now feel is the perfect replacement for me. Made by 511, well SOLD under their moniker, it is called the Atac PLx. 69l, 2 AAA, and the perfect grip having grippy ribs down four sides of the round barrel. It has a really nice pocket clip that is neither too snug or too loose. It is almost exactly the same size as a tactical pen so is perfect for pamts pocket or shirt pocket. Nice bright Cree led. Surprisingly bright useable light, very white and useable in the sense it isn't overly bright shined right at something close, but bright enough outside at night to light up a trail or driveway or interior of a car very well.

    Pete take that warning seriously. I recommend li ions because they are rechargeable and more powerful than regular batteries but you do need a dedicated charger and your light needs to be specd for them. The lights I recommend all can use both types so no worries there, but just make sure you read the specs for your light our else you can have problems

    I have gone solely to rechargeable in all my devices. They out power, and outlast all common batteries and of course, are re-usable! I have enough sets to power my flashlights (6) for a couple months without a recharge. Now I just need to find sets of 123 batts......

    I have them in my Surefire C3 that has a Cree LED conversion and in my Surefire shotgun fore end light. They work just fine.

    The Fenix LD-01 in stainless has been my EDC light for about two years now. Really bright with 10440's but battery life is too short with 'em. Still plenty bright with NIMH's . I wish the brightness levels were spread out more though. I like the size. You don't even know you have it on you until you need it. The threads have worn out within a year on every aluminum light I've had, but not this one. The stainless holds up much better in a pocket full of change and keys too.

    If you look at the start of this thread, the torch I posted up about is a lot like that. I loved it but it was so small, I lost it. The new torch is three times as bright but only has one setting so I may buy a new Fenix today to augment when on an install that uses 2 AA and has four settings and is 250l on turbo.

    After the few days I had it, the switch on the 511 Atak PLx went belly up. SOooo, I went back to Sportsmans and decided since i have just ordered a set of 8 rechargeable CR123s (thanks TT PAete!) I decided to get something WAY brighter that had variable power. For an added 35 clams I bought a Fenix PD32. It is bright at 300l on turbo but goes to 4 settings plus strobe, SOS and lasts a long time on the lower settings. Setting number 2 is brighter than the Atak Plx, and it is a better pattern. It even fits in the pocket a little better since it is half as long as the Plx. It is a little fatter round but that seems to make it stay in the pocket better as well.

    Here's my ultimate flashlight rig running 14500s and AA/AAA Eneloops, with ultra-portable solar/12v/wall charging options. My favorite is the Quark X run with a 1xAA tube and 14500... covers from 300 lumens to 300 hours in a tiny, EDC light.
