    Hi guys,

    I got my Mum a iTP A3 EoS and succeeded in converting her to an EDC mindset, at least in part. However for Xmas this year she has asked me if there is a lighter weight option she could turn too.

    The iTP is all she has on her keys, other than keys, and finds it too heavy. She is a teacher and uses it to get to her car a night when leaving work, there is a lot of outdoor stairs at her school, and not much lighting.

    So without resorting to specialist battery types like 10180s what would be the best, or more importantly the brightest light I could get her.

    I'm guessing the Photon? anything I haven't though of?

    I carried a number of real Photons over the years, and never found the switch convenient to use... you can save some weight by removing the chain and replacing it with a small split ring, and considerable weight by switching to a lithium cell... I just switched to a Fenix E05 2014 model and so far I like it

    What do you think would be lighter than AAA that is not a specialty battery?
    I don't know of another battery offhand that you can find everywhere that can be any lighter.

    The Photon battery is not exactly widely available is it?

    Streamlight Nano (uses 3 fairly common button cells), or if budget permits a Quantum D2 (uses a tiny weird battery, but it comes with the battery and it's rechargeable via USB).

    That's a Quantum DD (left) in the picture btw, but the D2 looks very similar.

    Led lenser do some tiny ones - k1 and k2 I think. Maplins do them (if you're uk based). Neither will be as bright as an A3 I'd have thought - by a distance. If you fancy splashing the cash, maybe a nitecore sens mini? Not sure it would be that much lighter though.

    The Thrunite Ti2 V2 - available at Amazon for $11 runs on a single AAA battery. It's an upgrade from the TiS model they offered last year:

    1. Single mode
    2. 80 lumen output

    Cons:
    1. Limited runtime (45 minutes)

    The TiS was the gift light I gave to non-flashaholics for general keychain use. Easy operation, pretty impressive throw and surprisingly bright for what it is. I often used mine for navigating the porch/stairs in early morning darkness, as well as checking out dark corners ten to fifteen feet away.

    It's not likely to be any lighter than the ITP A3 you mentioned above, but once your mom has a chance to try it, I think she'll like it - even if she might need to keep it in her purse for specific uses, rather than a pure keychain light.

    Energizer L92's (ultimate lithium) are disposable AAA's that are superior to the alkalines in various ways. They are also lighter at .3 vs .4 ounces.

    The only light I can get my wife to carry is a Nano. It's cheap enough I can watch her thrash it and not cry inside. :p

    There are really no smaller "standard" (common) batteries than AAA. Even button / coin cells can be tricky to find. Other options might include CR2, N-cell, or AAAA. And you've already excluded specialized ICR Li-Ion (like 10180, 10250, etc).

    Each of these has advantages & disadvantages.

    CR2 are very small and powerful, but expensive. NiMH N-cells are cheap & rechargeable, but not many choices for a torch. AAAA have very little power and can leak. ICR are complicated to manage safely. Button / coin cells are weak, oddly shaped, and inconvenient to replace.

    Oh good call Arch. Ounce for ounce a CR2 light like the Foursevens MiNi CR2 (or whatever they call it) is a nice little light. My wife had mine on her keychain for a while. It's tough to find a light that will push about 200 lumens for more than 5 minutes with any other "small" cell.

    But the CR2 is hardly a widely available battery?

    The AAA is where its at for this period.!

    It's available at most grocery stores at a premium or $1-3 a cell online. So basically it's no more specialized than say a CR123.

    The OP didn't want any "specialized batteries" ie: tiny lithiums that require tiny lithium chargers. A CR2 is about the same weight as an alkaline AAA. IMHO, if you can deal with the diameter of the cell and a lack of lights that take them it's the bulldog of lithium primaries.

    ^I'm with archimedes

    Is it the light itself that is too heavy? Or the keys overall?

    Not knowing the exact situation/complaint is there maybe an alternate solution?

    A quick google search says the light weighs 9 or 10g (depending on the site), the AAA I just weighed came in at 9g. A random sampling of keys all came in from around 8.5-10g.

    So we are really looking at 2 keys worth of light.

    Could she maybe separate house keys and school keys to individual rings?

    Otherwise an Inova microlight runs 9.22g with batteries, about half the weight of the iTP. It runs on 2x2016 Lithiums which aren't perfectly common but are cheap enough to have a few on hand in a school desk drawer, a purse or what-have-you -- a 5 pack of will run you $3 or so on Amazon. That said, the light itself runs anywhere from $5-8 and if you really needed to you could get away with it or something similar and just swapping or replacing the thing when it went dead.

    Of course I agree and disagree with this.

    The CR2 is clearly a great battery and I like my CR2 lights a lot but there is no way I can accept that availability is anywhere near that of a AAA battery anywhere I have been and I have searched a lot.
    I buy mine in bulk online as I do CR123s or I find them not to be practical for my needs.
    YMMV of course.

    Haven't got one (yet!!!) But looking at the specs it should work - she should be able to charge it in her car or home easy enough I'd though. No money at all really. I've copied and pasted the specs from nitecore (let me know if this is a no no!)

    • High performance LED produces 45 lumen on high
    • Built-in rechargeable Li-ion battery provides a runtime of up to 48 hours on low
    • Integrated intelligent Li-ion battery charging circuit (micro USB charging port)
    • Single multi-stage switch offers access to all functions via one-handed control
    • Features two brightness levels and infinitely variable output mode
    • Features extremely wide 100° flawless beam to light up peripheral vision
    • Constructed from durable Polycarbonate materials
    • Dual metal key ring connector withstands up to 35 kg
    • Impact resistant to 1.5 meters
    • Extremely lightweight, compact and portable
    Dimensions
    56.5mm x 21mm x 8mm (2.22” x 0.83” x 0.31”)
    Weight
    9.6 gram (0.34oz)(with battery)

    Well a CR2 or an AAA light with the lightest cell is going to weigh about the same. IMO, a Nano or Photon would be a good "lightweight" light.

    Ok. So we are debating the phrase "specialist" which we don't exactly know the OP's opinion. It's two people talking for no reason whatsoever. ;)

    The reason why the CR2 is less widely available is it's designed primarily for cameras where as the AAA is used in everything. If you are fine with a light that pushes 60-80 lumens AAA's are great. If you want 200ish lumens you need about 3v. You can still buy them online from multiple places and they last 10-15 years. If they are too specialized then CR123's probably are as well.

    Just FYI, button / coin cells (and devices which contain them) need to be safely kept away from children, as they can be seriously hazardous.
