Round high cri emitters for Convoy Z1

Hi everyone- I do photography and make music videos for local bands as a hobby. I have often used flashlights as a quick, easily portable light source (and they just look so cool!). I have gone down the rabbit hole thanks to finding this sub and purchased several Wurkkos lights looking for something usable for various scenarios. I bought a TS27, TS28, TS11, TD01C, and then got a few with Nichia 519a: the TS26S, WK03, and an FC11 2700K (can’t remember which emitters in that one)… and then got a Convoy C8+ 519A 3500k and (just to see how it would look) a Convoy Z1 519A 1800K. The adjustable spot/throw looked great except that the spot was square. I think I’d like to try a few Z1s with different high cri emitters from 3000K to maybe 5000K. Can you recommend high cri emitters that would make a round spot when it’s dialed all the way down? Any help would be appreciated. I think the Z1 would be what I need. I’m going for style over throw but throw is great too. Sorry if this is long winded and thanks in advance for any help. I’ve really been enjoying the bean shots and specs in this sub. The picture is of the C8+ 519A 3500K on the left and Z1 519A 1800K on the right.
