50% is very Inefficient....get some brain maybe it helps!
If
you are
that butthurt-desparate to prove me wrong by quoting and refuting that tidbit I can only assume you ran out of valid arguments that actually refute the main point.
You guys have a real hard time understanding percentages and relatively. If you run your photored at 50% (in practice) you choose to run them at 50% efficiency. If you run your cobs at 60% or at higher bibled claims that is relatively a high difference. In fact, it's roughly the same difference between the cri 80 and 90. When it suits you 17% is a lot, when it doesn't suit you it's meaningless. That's all your intellectual dishonesty, your bias. I can do that too.... if you run the photored more efficient, it would be for a narrow part of the spectrum and not outweigh the efficiency of the white cob, and if intensity is all that matters, you should thus add more of 4000k, not add photos....
The whole reason you use the wrong high blue white cobs is because they are easy and cheaper to run more efficient for high amounts of light. If you were honest you would have posted how many xpe you need to buy and build into the system to make up for the difference, and add what they'd really run at an produce in total.
In any case, adding those photos helps but won't improve the spectrum as much if you're using 4k, as in psua's example case I was obviously referring to. Pretending 4000k+photored xpe is better than 3000 (or even2700) cri 90 is just...
If it happened to be the other way around and white cob were red leds with phosphor pushing the light ouput to the left of the spectrum you definitely wouldn't add as much blue, and used some of my arguments to refute the value of adding that much blue... Hypocrites.
Good luck trying to change the argument, I'm sure there are plenty you
can win.
You can choose the intensity you want to run within reasonable limits, with a hps, leds with a suboptimal spectrum, or leds with a more ideal spectrum. If maximum intensity is key (it's a very imporant factor but not the only one) the more reason to use an optimal spectrum. With hps you will burn the plants before you reach the max intensity, not just from the IR, while with an optimal spectrum you can push the range where it actually makes sense without pushing range where it doesn't.
Max intensity per cob does not determine the max intensity on the plant. Max intensity, high efficiency, and a better spectrum are not mutually exclusive.
