De-domed LEDS like the factory de-domed XPL-HI are better for throw.
My C8 and L2 both have the XPL-HI V2-1A. The L2 is the better thrower, which is to be expected since it has a bigger reflector and the LED is driven a bit harder.
Also, cooler tints putting out a few more lumens are reckoned to be better for throw.
TBH, I find the C8 is plenty for most things and I use it more because it’s handier, but it will depend on your needs. The L2 has tremendous endurance especially with 2 x 26650. I use my M1 more than either and it’s not a thrower.
