Can you tell a difference between the brightness using the three AAA batteries versus the 18650?

I'm sorry but I can't. I bought it for my son for Christmas so I don't have it to compare.

Brightest is very close to same, but battery life is much shorter with aaa batteries.

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.

No, the 18650 is both slightly longer than two CR-123a's and larger in diameter. Also, they run 3.3-4.2V as opposed to 5.6-6.4V total for two 123a's - the LED flashlight must be designed to accommodate them. Many two '123a cell lights made in the PRC, like my Olight M21 & M22 and Fenix PD-35, will use them - and work better, too. None of my 2-cell US-made Surefires will fit them - the body tube's ID is too small.

I got the light and a holster. I have to disagree with William - I noticed no difference between Ultrafire 26650 and Samsung 18650 (I guess Ultrafire overstates its capacity). Also no increase in brightness by using 3 batteries - just more heat.

Inherent brightness is controlled by whether on battery or not. As to ambient light sensing: mine works well.

If you use AAAs and use it often thru out the day ( Contractor and a mechanic) you will use them up. It will SUCK them up!!I have 6 of the 18650 an this is the best battery ive ever had the light output is comparable to a large mag light an goes thru half a battery a month if you get this light buy a 18650 battery an charger combo 12 bucks extra an the difference will blow your mind. or you could waste that same cash on aaa an think you got a bum light. we use this light daily for a couple months good light also have a 501b an a couple 502b's awesome lights

This model is 500 lumens. I doubt you would be able to tell the difference between the two different powers.

18650 Batteries come in two versions, one "unprotected" and the other "protected". The "protected" batteries are just a tiny bit longer than the other. That might make the difference for you.

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.

truthly I don't know. they are flat top batteries and appear a little bit bigger then actual 18650.

Not sure of the reason for the variance. From what I understand, if you use rechargable lithium batteries, you'll achieve maximum lumen output.

I just ordered this battery for it UltraFire 3000mAh 3.7V 18650 Li-ion Rechargeable BatteryI haven't got it in yet so not sure if it affects brightness with other batteriesPressure switch should be as simple as squeezing together opposite sides of small flat end piece

The 18650 is a number that represents the dimensions, aka size,, and the mAh amperage current capacity indicates the bigger the better @ same voltage 3.7-4.2 volts,, so YES aim to purchase the higher mAh. There are really COOL Battery Forums that explain in more detail.

No, they are not the same battery. The 18650 is a rechargeable lithium ion battery. The cost is reasonable and, having used about 8 of this type battery, I can vouch for their longevity and utility.

The light uses 3-AAA batteries in a cartridge. I would think it's not compatible with a 18650 but am not sure.

I must confess that I do not possess a meter to measure lumens. I can, however, assure you that any flashlight being operated by a 3.7 V battery will have a startling effect when suddenly switched on. I am more than satisfied with the capability of my unit. If you purchase one and find yourself dissatisfied with the intensity of the light, you can always return it. I hope my comment will assist you in your decision. Have a nice day, Steve

Ther only one LED but may have three light settings. There is only one 18650 battery that powers the light. The battries are from 1800-4100mah.
