Thanks for bringing to our attention.
Odd they went with 2 18650 so 2x3400 = 6800 rather than 1 26650 5000mah, so wider diameter instead of longer.
Also, you'd predict a sibling of the LC130 which is 2 26650.
As the days shorten I am using my LC90 more often now. I love the LC40 pocketability and the LC90 zoom. I really doubt I would personally ever buy the double-length LC90, because the LC130 I have is, in part, a room illuminator via putting on its flat end pointing to the ceiling, a longer torch will be harder to balance on its end.
