Thank you very much.
But is the red chip suitable for a grow light? dont we run into the same problem of the phosphor layer being less efficient than monos?
I have read a lot of threads here and have some LEDs myself. I agree that strips seem to be the best atm. Not saying that COB are bad but I just prefer the strip builds.
But I cant remember reading anywhere your opinion on the recent best building option. ( like what ratio between strips and monos, spectrum etc.)
Asking because I need a new light and I'm always wondering which strips to use. Before discovering the optisolis I wanted to go with the EB gen 3 series with 660 and 730 monos. Maybe some 430 and few UV.
But I'm totally lost at what ratio... do i just suppelement a few 660 and even less 730 or do I add a significant amount of 660nm.
Do you maybe know of any source for cree XPE-2 660nm strips besides cutter? (really nothing against cutter.. I love this shop but it would be easier for me because of trouble with customs to source it from anywhere else but australia)
At first I wanted to just supplement a few 660nm with even less 730nm for the emerson effect, but then read about a LED called Sanlight Q6W. They pretty much perform as good as the fluence spyderx but use a very different approach:

As you can see they use much less LEDs and about 53% are just red mono's. They have their chips custom made by phillips.
Considering how hard they are driving the LEDS to reach the wattage its obvious that the LEDs arent run very efficient like the fluence with its tons of LEDs. But they still perform quite equally.
They also have a higher peak at 640nm than the peak at 660nm. Im also a bit puzzled by the 440nm peak... The company claims they chose it so the plant wont produce more leafs than it needs. Called it hormonal controll.
People also report no stretching and very short nodes despite this little blue and high red ratio,
considering how well they perform I thought maybe it is true and the balance of a grow light should be more towards the red area...
I would really love to hear your (and of course everybody else's) thoughts on this.
edit: of course I meant the sanlight performs as good as the fluence in g/watt. Not like the 200 watt can beat the 600 watt in total.
