Ideas for e21a and optisolis hosts

Normally the non K variants of the 219B are on the BBL or even above and not very rosy at all. However, the SW40 I have are from Clemence, which is very rosy not unlike the SW45K. The D220 version of the E21A 4000K looks very similar to the SW40. Nearly identical but maybe a tad bit less rosy. I think I like the E21A slightly more because it is domeless so the tint is more even. Both are beautiful. However, the most recent sold out batch of E21A 4000K is D240, which is basically right on the BBL so it is not as nice and rosy. The good thing about E21A is that you can mix emitters in the quad board so you can get the same nice rosy 4000K with 2x 3500K + 2x 4500K. Results may look even better than the D220 4000K since mixing CCT usually results in higher Rg values for more saturated colors.
