    They should be pretty much about the same.
    Its more about which battery you prefer to use.

    i just found these comparison shots:

    http://fonarevka.ru/index.html?scene=0&light=90&mode=0&shutter=0 --- 18650

    http://fonarevka.ru/index.html?scene=0&light=91&mode=0&shutter=0 --- 3 aaa's



    not sure what kind of aaa's he is using but the 18650 is significantly brighter


    i have nimh aaa's that are 1.2 volts and 900 mAh, so that should be the same as a 18650 with 3.6v and 2700 mah, not sure what normal alkaline aaa's are.

    Yeah, the problem is you dont know what batterys they used for the test.

    Rechargeable AAA are usually around 1.2v and Alkalines are around 1.5v, and a 18650 is around 4.2v when fully charged.

    So, possibly they used rechargeables!

    I would normally tell people to go for 18650 due to better runtime and usually better brightness (It all depends on the light), but some people want batterys they can easily get their hands on or that they have lying about the house.

    The thing with NiMH, they do have memory and if you dont have a decent charger, then over time, you wont get the best out of them.

    If you're going to be getting into flashlights, then i'd recommend getting 18650's.

    okay thank you for your help, btw its an energizer charger/batteries, so it should be good but i will probably get a 18650 charger from here and some batteries then i will be able to buy some other 18650 flashlights later on, the only thing is after reading the reviews on alot of those chargers alot of comments on the forums say they can blow up/start on fire, so i am a little skeptical about buying them

    sku.14885 and sku.6105 seem to have mainly good feedback
    and sku.20392 for batteries.

    The charger i use is a BL700, i ended up getting that as all the batterys i had were rubbish due to being charged with a basic charger for years.
    It revived all my batterys and let me know if any were fit for the bucket.

    Its a bit pricey, but now i have NiMH batterys i can use and i also know the capacitys too.

    In my opinion, you dont really need protected batterys unless you're using flashlights that take more than one battery.
    You need to stay well clear of sku.14885, as thats the one that was included in the JFT flashlight bundle, and none worked out off 7!

    The sku.6105 is the only one i get and i use sku.6979 batterys.

    Click on my reviews and you'll see what i wrote about them.

    I have this one and C30. So I prefer C30, because this one has bluish light, driver is bad (every time you swith on the flashlight, driver will change mode). C30 has more yellow than that one and a little brighter, IMHO.

    P. S. С30 - 3 AAA eneloops (eBay)
