Actually, maybe +/- 20 seconds or so is possible? Percentage wise it is a lot thenā¦
Wait, the temperature is set at 50 degrees, so going from 20 or 0 degrees ambient temperature to 50 does indeed make a differenceā¦
I would imagine if these were high CRI Crees they would be advertised as much. Assuming these are the low CRI Crees their CRI is likely in the high 60s bottom 70s which is a far cry from the Nichia 80+ offerings.
My subjective opinion of the 80+ 5000K 219C vs. 90+ 4500K 219B:
219C is much brighter --- noticeably so
219C is just as neutral, if not more so (the 4500K always looked a little rosy; the 5000K does not)
Colors look very close on the 219C. The 219B may render flesh tones a little bit better, but really subjectively for flashlight use you are cutting hairs.
I have not put a 219B into any of my personal lights since I got my hands on the 219C. The 219C has been my #1 personal light LED since I got them.
For the most part the 219C and its 80+ CRI is quite enough. The 5000K CCT is perfect and because itās absolutely stable from the spot (if you can even call it that) all the way to the spill with no shift, you canāt really criticize it. Iāll take this form of beam every day before a high CRI light that doesnāt have a stable CCT. I havenāt seen the 219B Meteor so cannot comment on that, but generally I really like the rosy tint.
I havenāt measured the Meteor, but hereās a Reylight triple with the same 80+ CRI 219C:
