Just about all I keep for leds any more are XM-L and the Nichia. I figured to put the T6 3C in this one. 2.8A driver for the T6 and a single 7135 chip for the leds. 20 leds @20mA each = 400mA and a single chip should do about 350mA, so about 17something mA for each led. Hopefully it will work out for this.
It’s only because I bought T6 3C from China. All I could find at the price I was willing to pay, so that’s what I will put in.
I would put in a Nichia, but the new batches of the 219 that I have gotten from IS are Not warm White and I suspect, not high CIR either. They are borderline neutral to cool white and don't look like high CRI from what I can tell with my eyes.
Yes, I just got some last week. They are nothing like the original batch. I would rate them at 5700K and 85 CRI or so. Just by eye, so you know how much that is worth, but for sure, much whiter than the first batch. The last two batches have been consistently whiter, but maybe that first batch was a different bin.
