we need to demand that mfg's use 219C and stop 219B emitters agreed?

Well, you have CRI, and you have the designation for the colour temperature. But I’m not sure (I’m a noob) whether the tint is designated at all. Isn’t that something that is just being observed by end users?

Here’s food for thought Mr. Ronin:

- Noctigon Meteor 219B (5000K 90+CRI): 4450 lumen

- Noctigon Meteor XP-G2 5700K: 7400 lumen

- Manker MK34 219B (unknown CRI): 6500 lumen

Manker MK34 XP-G3 6500K: 8000 lumen

Now for the cool white tint, the Manker produces 8000 lumens compared to 7400 lumens for the Noctigon. Slightly different colour temperature, but ah well. So you’re going from 7400 lumens to 8000 lumens, which is like a feasable increase going from XP-G2 to XP-G3, assuming you have comparable performing drivers.
But if you look at the Nichia variants, you’re going from 4450 lumens for the Noctigon to a whopping 6500 lumens for the Manker! How is that possible? So, is it possible that the Manker is using like a 70+ CRI 219B emitter, if that exists (I really don’t know)?
Is this odd or what?

The MK34 numbers are inflated not sure why you take them as absolute numbers.
Check out some real output numbers:

It is between 6200 to 6800lm for max. 20seconds no matter if it is cooled or not cooled.
Considering it is using XP-G3 with much lower Vf’s that the XP-G2 I find that max output rather underwhelming for 20sec max.
My 219B-V1 M43 with only 4450lumens does 20Kcd even after 30seconds (measured myself even if rating is the same), their XP-G3 is claimed to do 20kcd, may not be true just like the max lumen output claims.
