I just built my other MT-12 with a 219C 4000k 90+ CRI.
So it is 4000k vs 4000k and 80cri vs 90CRI.
The interesting part is how close they are, donāt get me wrong they are still quite different but way closer then I expected them to be.
The hotspot tints are quite close, the 219C is a bit rosier but that could easily just be from the 90CRI. Same for how it looks, about what you would expect for 80 CRI vs 90CRI. The XP-L2 just seems to have a bit less red/more blue overall.
The corona on both has a different tint then the hot spot. It is quite close to each other in size and shape of this corona. The nichia doesnāt shift the tint as much as the XP-L2 and remains more even overall. The XP-L2 seems to actually get warmer in the corona with a bit of yellow.
The real noticeable difference starts at the spill.
The nichia gets cooler as it moves into the spill but it is much more mild then the XP-L2 and it simply changes color temperature, not the tint.
The Cree on the other hand gets significantly cooler in the spill. The offset from the spill to the hotspot is what causes the beam to not look good on a whitewall.
I have not tried the nichia outside yet but I tried the XP-L2 last night and outside it looked good, you donāt notice the tint shift much outside. I look forward to the 219C. I really like these hosts.
Oh and some quick data on the 219C as a comparison. It is making about 850lumens @ 3A vs 1250 for the XP-L2 and in āturboā (have to limit the duty to about 75% to keep it from overloading the 219C) it makes around 1100.
The hotspot is about 65-75% of the XP-L2 size.
Some quick throw measurements.
219C Turbo - ~1100 lumens - 27Kcd - 330m
219C @ 3.15A - ~850 lumens - 22Kcd - 300m
XP-L2 Turbo - ~1900 lumens - 30Kcd - 350m
XP-L2 @ 3.15A - ~1250 lumens - 18Kcd - 270m
