A diode produces a specific light spectrum, two diodes of different spectrums do not make an average spectrum. A 3000k spectrum diode produces wavelengths beneficial to plants not found in 4000k and 3500k spectrums.
A 2012 article about colored diodes? Really? How does that help your argument this is a totally different tech.
It is the amount of heat they produce. which is negligible. If you need to pass 250mW you use a 250mW resistor, for example. The board doesn't have to cool shit.
3000K, 4000K et al are simply a kelvin value of color temperature which produce a range of lightwaves, measured in nanometers, ie. 450nm, 640nm, etc.
Dude you have no clue what you talking about. When you bash something at least have real experience not something you read online. I use 3000k, 4000k and 5000k COB fixtures and strips for growing and all 3 cct colors combined produce way better results than each one individually. I have them all on at the same time and the plants that under just 3000k visibly stretch a lot more than ones under 5000k & 3000k combined. So please don't spread unconfirmed BS.
Yes, they actually DO. Stephen has shown this using a spectrometer.
No it does not produce averaged lightwaves, it produces an averaged SPECTRUM. CCT describes a SPECTRUM, not individual lightwaves. Both CCTs produce lightwaves ALL ACROSS the visible spectrum (not just two frequencies), differing only by the amount of photons at various frequencies. it is the amount of photons produced at various bands that determine the CCT. As CCT increases the spectrum shifts towards the blue end.
I really don't care what your individual experience is, TBH. CCT is something that is easily measureable using a spectrometer.
I agree with you about your description of CCT.
We simply don't agree.
May be get some experience then come back
Maybe get some intelligence and then come back. This is simply not debatable, nor is it an opinion - it is a simple point of fact. CCT is determined by spectrum which is measurable with a spectrometer, and has been done by Stephen of HLG to demonstrate this exact fact.
No, you really are dumb, take a look at 5000k chart, 3000k and 4000k one, so you saying when they are combined make up 4000k no way. 5000k has more blues, which 4000k does not, same for far red, 4000k barely has any, when 3000k over 15% of the spectrum. So combining spectrums does not equal to median one, don't you get it?
Do you grasp the fact that monochrome light does not have a "CCT"? Your argument above makes no sense and does not apply in any way to combining WHITE LIGHT spectrums. You are in effect, pointing at rabbits while arguing about the existence of chickens.
Looking at curves is misleading. Sure it looks like you are just adding a chunk of red light from 640 - 700nm - but you are also adding everything on the curve that's below 640. Once the combined curve is re-normalized all you really have is a red peak shifted some. Again, at the risk of repeating myself, this is something that Stephen has actually measured with his spectrometer and posted. You don't really get anything that "wasn't" there, you just get more of EVERYTHING with the ratio shifted some. All of those red wavelengths from 640-700 ARE present (in the 400K), just not as much of them. if you want more far red, then just add far red, without all the rest of the spectrum that comes with a white diode.
CCT does not equal wavelength (nm).
No they dont... high cri was only relevant because it coincided with deeper reds but still a photon filter otherwise cri tends to be worthless for measuring radiometric output [read:non_quantifiable]. Newer gens like vero have gotten better but they still bottleneck photon delivery at the expense of red delivery....besides far red and far blue are still in much debate about in vitro physiology occuring....
