Now that all this has been said, what do you think of a theoretical greenhouse supplemental lighting that is mono blue for vegging and mono red for flowering? Let the ambient sunlight take care of the rest... would enough green and amber be getting to the plants on an average overcast day, in the greenhouse? I know it would probably be more effective to have a 4000K for vegging with a supplemental red, but please humor me!BTW ...I'm not quite sure if this the appropriate thread to post this ,but what the heck ...
I'm gonna do it ...
Maybe it will be a bit of help for the FCO team ....
I've multiplied the McCree curve ( aka "Photosynthesis Action Spectrum ) with the Absorptance curve of Cannabis Sativa
species ....
The result is ... a mixture of absorptance & RQE per nanometer ...
A combined curve that shows the overall photosynthetic potential (! ) per nanometer ...

The highest " photosynthetic potentional " ( PP ) ,at the range of 400-700 nm ,
is located at 625 nm ( PP=0.893 ) .
The lowest points :
1 ) At 530 nm (PP=0.592 )
2 ) At 400 nm (PP=0.590 )
3 ) From 688 nm to 700 nm ( PP= 0.586 to PP= 0.31 ,respectively )
PP >= 0.8 have the photons of the range 582 nm up to 679 nm ( deep yellow to deep red )
Cheers.
It's A lot easier than using a holder!
so you're running the Luna300 at about 250W right?This is a size comparison between the Luna 300 and the Citizen CLU056.

So for 250, you need meanwell HLG240's for each one? What amperage? What's their forward voltage?I am running them at 120 w, 250w, and I have run them 320w. 250w is where I like so far.
Ah. So there's no reason to use a Constant Current driver with just 1 cob really huh?HLG240h-48b or the HBG240h-48b. Same driver different case. 5 amps. 46v.
I still have no clue how by they work compared to the C versionI was told by Flip Chips engineers that because of the way the wire there COBs that you can run them in parallel without any problems. And to your question, no.
You keep forgetting that that driver is a Constant Current driver, it just has a voltage limit. As long as you are under that limit it runs Constant Current @ 5 amps.
