It's beautiful, no donut hole.
The focus on the Makai needs a bit of distance, so close up it will have a bit of a hole with any LED. I can't give an exact measure right now but it's a fair bit more than say a Haiku. E.g. using a guesstimate, if a Haiku needs 10cm then the Makai might need 40cm (from the target of illumination).
Are you getting the hole (with the XPL Hi) at reasonable distance?
I do have an XPL Hi engine but I'm not tempted to remove the 519a de-dome and haven't tried it yet.
The beam with the (5700K) 519a de-dome is very clean with minimal to no tint shift in the corona/spill. Lovely clean and white. A really nicely balanced combination with the reflector all round.
In time I'll add some beam shots etc.
