Question: The technical details say "8 Lithium ion batteries required." Are lithium ion batteries required or can it use other types of AAs such as NiMH?
Document: It is the size of an old classic 2-D flashlight but uses 8-AA batteries in a cartridge holder. It can also run on just 4-AA but for a reduced time (about half). This unit accepts AA batteries in common Alkaline (~ 50% performance), rechargeable NiMH (~ 90-95+%), and AA Lithium (100%). They got all the features right - or as right as possible with current affordable technology.
I recommend Sanyo Eneloop rechargeable NiMH batteries (1500 charges) and a best-quality smart charger (3V 4-cell La Crosse Alpha Power BC700, or 12V 8-cell BatteryJunction M-8800 also usable in cars). The Maglite ASXD036 belt holder fits, but the plastic ring smells terrible. If treated well, this Fenix light is a lifetime flashlight. It is so well made it is worthy to simply display and admire.
I use 8 rechargeable AA eneloop batteries, and this light can last a good long time between recharges.This thing is bright enough to give someone serious temporary blindness at night.I live on some land, and my driveway is 850 feet long.
), power source (battery types and long-term cost of use), battery life (run times at various brightness settings, level-light electronics that hold a constantly bright beam as the batteries drain, &#34;parasitic drain&#34; electronics that can drain your batteries when not in use or in long storage, etc. ), and of course the all-important LED used (brightness, color of light, energy efficiency, heat, lifespan, etc.).
This is bright but doesn't have the same CRI as an incandescent - just so you know.I have not tried any of the lights that use CR123A cells or any of the special lithium cells, but if you want a really good flashlight that uses cells that you can buy at any CVS, this might just be it.
I've tested it in the neighborhood and in the thick New England forests for the past few nights and the neighbors peer out and phones start ringing. Local police even cruised by and wanted to know what we're SEARCHING for! They now own a FENIX for their own. If you are serious about emergency preparedness, this is the light you need. Worth EVERY penny. I suggest a 16 pack of Sanyo Enneloop "AA" NiMH rechargeble batteries with charger and a backup pack of premium alkaline batteries.
During my two weeks in Kenya I used this light a fair amount but to my surprise I didn't even fully exhaust a single set of batteries, which is good considering it takes 8 AA (that's almost a negative but I considered all the other flashlight battery options and really wanted to stay with a common type, plus I already have about 60 AA Eneloops)!
I received my new Fenix TK41U2 today and was literally blown away by the "brightest light EVER" from just 8 AA batteries! Starting with the super-clear lens and reflector cone all the way to the knurl on the end cap, the overall quality construction is flawless! Dark glasses, although not practical, should be on stand-by due to 860 lumens of extreme brightness! :-)  The icing on the cake is the 30-month warranty and free repair service!

I won't go into details, as there are many descriptions that are spot-on (I agree wtih all the positive reviews).
Answer: yes
