Do these numbers sound right? XP-L vs 219C

I made an X6 triple with XP-L 3Ds and it measures 278 meters.

Now, I finished up a X6 219C 80cri triple and it measures 305 meters.

Is that about right? I thought the 219C was going to have much better throw than just a 27 meters increase over the XP-L.

Sounds like it could be right to me. I tested a 219C 70+CRI in a trustfire A8, which has a ~440mm^2 reflector, and got 31.8Kcd at ~5.5A, which means the emitter has a luminance of ~72cd/mm^2.

I tested a domed XPL V6 1A in a EE X6, which has a ~609mm^2 reflector, and got 49Kcd at ~5.5A, which means the emitter has a luminance of ~80cd/mm^2.

Your emitters are slightly different than the ones I tested, but this shows they are not all that different in throw.

Thanks for the response! :smiley: I was just a bit worried that I did something incorrectly when I reflowed the emitters onto the board which could have caused what I thought was weird performance. I expected more throw.
