I agree on the mah capacity being a downside, but usually these lights are purpose driven and rely on different bulbs and drivers to produce either lumen and/or longevity. To me it is amazing I can crank out XX amount of lumens on high and XX amount of time on med while still bright because of the high efficiency of the driver. You're exactly right on mah claims on cheaper batteries, usually a boast or in ideal conditions which would never be attainable in the real world.
Although the 18650 is slightly fatter and longer than the 14500, the end result is usually a much bigger flash light cranking out more lumens and more runtime. Remember the thread is EDC pocket lights! You can really see the size comparisons in this photo I took:
Left to right: US quarter, eneloop AA, 18650, olight i3s EOS, eagletac d25a, olight s15, ultrafire zs-2, ultrafire 502b, olight m20x and m21x
Big differences on AA to 18650! For EDC I would much rather the smaller AA or AAA than the 18650. Also most lights that can take 14500 also use primary cells too which greatly extends runtime. I just like using 14500s for the added lumens.
Very cool link! Bookmarked. I was hoping he'd have a review on rechargeable ni-MH cells like c and d as that is what I am currently in the market for. I have a thread on CPF asking better brands/chargers and such.
