    Holy moly, what a difference, LMFO! Wonder if they have the same density as the ones from CRI80.. Can't wait to see the final weights!
    Hope you feel better and you hit the bug, which bothered you..

    That spectrum shift to slightly more energy in the deeper reds seems to make a difference, at least in flower. Same strains always seem faster with trich development and more flower. The light produced also has a warm feel to humans.

    Noob question; how do the lm563c diodes from Quantum Boards rate on this CRI/R9 mumbo jumbo? Will they create one that is R9 or whatever? Or at 80cri is it already OK in r9?

    The differences in the various spectrums in white LEDs are small in the 3000k to 3500k area. In most cases the 90 cri rated LEDs make a little more and deeper reds. It does seem to make a difference.

    Keep in mind that the growth differences are small and 70 or 80 cri COBs or boards kill any other light source. If I didn't have plenty of COBs and high end white panels I would be playing with boards!

    what about manufacturers who label their led's @ 80cri but when you test them they come back @ 93 cri,still no r9 in those ?
    @The Dawg nothing wrong with short n stocky,chics dig it lol. This thread has made it easy for me to continue my dislike for the shitizens haha.

    No idea. I speak only for their data sheets . You would need the tools to measure .
    Many guys like Growmau5 and ledgardener have these tools but took for granted the average CRI from r1-r14 you could actually have a 99cri with 0 R9 in theory.
    In practice R9 starts to increase above 90 CRI

    I wouldn't bash the Citizens so much, they have an extreme high cri 97+ and R9 COB, but it trades off efficiency for that .

    What we have yet to discover is how important is R9 . Or even if it is is important at all. These are just second guesses so far

    looks like a baby ganoderma applanatum. they're considered
    to be a medicinal mushroom. taste is bitter as hell, they're usually
    consumed in tincture or tea.
  17. OHH...I GET IT...different light spectrums can change the way a plant grows!... your friggin genius... I don't care what you had to go through or how much money you had to spend to figure that Golden Nugget of information...

    Ok Me Understand The Frame On The Left Is Made From 1 Inch Angle Aluminum And That's A Solderless Design To Attach The Cob To The Heat Sink All Is Needed Is Thermal Paste And A Screw Driver :hump:
