The light output is only slightly less with the 18650 when the AAAs are new, but unless you were to view two flashlights side by side you wouldn't notice a difference. Even then the difference is very small. The big differences are the AAAs discharge quickly compared to the 18650, and of course the 18650 is rechargeable. I found a low cost charger with two 18650 batteries combo and it has been great. I used to use a CREE using a single AA due to the high drain of the Ostart, but now I am using the Ostart all the time. The 18650 is a big winner.

All that I've ever used is 3 AAA's but I've wondered also . If you find the difference please let me know . Thank you very much .

I use the 3AAA batteries because the light intensity is the same but the AAA batteries are Cheaper and easier to change. The light intensity is the same as far as I can ascertain.

Considerable difference. You can get two 18650 batteries with charger & free delivery for $10 - do it.

No, but you can use the CR123A, just don't use more than 3, and of course the 18650, and 3 of them as well.

My light works fine with 1.5v AA batteries. But the 3.7v Li Ion batteries make it brighter.

One battery stores more energy than the another as in a flash light will make light longer with 5000 mah than with the 1650 mah battery Also there is a battery style that is call a 18650 that is 3.7 volts and very in amperage.

It can use either 3 AAA, or one rechargeable 18650 battery. It comes with a holder for the 3 AAA, and also with a charger and two 18650 batteries.

Ive used it with one single 18650 and with 3ea AAA NiMH batteries in the holder. But what I'm curious about is will it work using 2ea 18350 batteries loaded?

The light takes the 18650 3000mAh 3.7V Rechargeable Li-Ion Battery. You have to buy that separately. Try an UltraFire, they work fine. BUT...as for the light, see my review on this scope combo. The light is the worst part of it - you'll want to buy a better light. Still worth the cost overall.

I use the 18650 batteries , And yes I do believe there is a difference between the two batteries I think its brighter with the 18650

You can use three AAA batteries with the supplied battery pack, or you can use one 18650 (i.e. Ultrafire) battery without the battery pack.

It depends on the battery. Aaa batteries go fast. The 18650 3400mAH take about 5-6. I love my i4!

18650 3.7 v0lt, up to 3600 mAH, 4 each, get ultrafire or surefire for quality. Try onlybatteries.com.

With all due respect, if you do not know what a 18650 battery is, you should probably look for another flashlight that uses AA or AAA. There are a lot of possible dangers associated with this type of battery if you do not fully understand it. There is a 4 dollar flashlight on Amazon similar to this that uses a single AA battery (search for "cree flashlight" - FordEx Group is a popular one).

I'm not sure what the best are. The batteries provided were one use of course. I've got ultrafire 18650 rechargeable right now.

Usually these flashlights that specify 18650's will also take two 123a's in series. The electronics makes the adjustment.And 123a's also have a cousin the same size that is rechargeable.And remember the universal rule of Li-ion batteries; the cheaper and more off-brand that you buy, the bigger the mAh rating lie!General rule for 18650's is that none will ever actually test over 3400 mAh.

I have a lot of different UltraFire flashlights. All are very bright. if the model does not use the 3.7V Lithium battery, the model is designed for three AAA batteries. I never saw a model that uses AA batteries.
