are you still happy with your F90s?
the concept is quite interesting, i wonder it havent cought more attention here.
would like to know the ppfd output, looks like its quite good.
"For traditional LED technology, higher CRI results in a lower efficacy. By replacing broadband red nitride phosphor with narrowband red Potassium Fluorosilicate (PFS or KSF) phosphor, the F90 LED products can achieve today’s CRI80 LED efficacy with a CRI of 90. "
would prefer the 3000K, which spectrum is given in the datasheet, above is only the 4000K
edit:
hm... checked the product sim on the quick and at nominal the 3000K are just 2.5ppfd, thats a bit average.
could be wrong, need a bigger screen to really check.
