Fenix LR50R

So Fenix is coming out with a 4 pack 21700? Is this the first of its kind? I see they started naming their LED’s also again.

It uses battery pack or 21700,but when it uses 21700 the max output is 6000 lumens.
Fenix seems to have solved the problem of green light color that has been criticized, so they starts to name LEDs again.
