Yes. If there are demands for 2700K - 4000K, I’ll definitely purchase more of those CCT again. Expect early February delivery. Together with a bulk 4500K 219C for some US/EU manufacturer. As usual, nothing less than 3 steps binned
@djozz
Can you take me from the list for now?
After reading this i want to wait for the 4500K 219C (and hope for some in 5000K)
Because the Q8 will also take some time i can wait a bit longer.
Will it be possible to order this next time (February)?
There will be NO 4500K 219C higher than Ra8000. At least for the entire 2017 production plan. I’ve asked, checked, and got official confirmation (today). If you really want 9050 4500K Nichia LED, then 219C is not the LED you’re looking for. Try 219B or 144A instead.
Most of you might know the following chromaticity chart with ANSI quadrangles by CCT and Cree’s binning system. You can click all of the following images for a higher resolution version.
Now, with the MacAdam binning system that Nichia uses for their newer LED’s, I overlayed Nichia’s charts to make it easier for you to see the benefits of getting 3-step (sm_3) binned emitters versus 5- or 7-step binned ones (sm5/sm_7)…
Thanks for the overlays chouster, very helpful.
For me it all depends if the 3 step macadams is a benefit or not. I really prefer the rosy tints so anything in the Cree 4A, 4D, 5,6,7 (A1, A4, D1, D4) section is my choice. It looks like the macadams 5 and 7 step has a chance to land in those areas better than the 3 step but then they could also get up in the green/yellow tint section as well.
