Shame these chips aint more available bro but i’m no sure we really need em, they do look good though eh Export Estonia’s got clu38 at 5000K which is apparently equal to midday sun according to some and also about the same as a metal halide fixture (white).
The thing that gets me is full sun in a clear blue sky can produce light at up to 10,000K or higher so there is your royal blue. Looking into it further but not too much info on plant growth under artificial lighting at such high K temps. I did notice that the new version Hans Panel has had it’s royal blue cobs changed for white ones but no pseudoscientific explanation available for a change. Just it looks more natural. Maybe the blue aint needed or maybe they cost too much. Or maybe both

As a note, blue max lighting claim 5900K is the closest to natural daylight you can get in the home. as long as the CRI rating is 96 plus
