Hi,
sry im am new and I bet you heard this already a 1000 times. But im still struggeling to find the right answer.
There are so many different opinions here in this forum and also every seller of those led fixtures has its own ratios of leds in different wavelengths, its really confusing.
Here is what I have, all 3W 700mA high power mounted on star:
data are the typical values
21 x 660nm deep red, 80lm
20 x 630nm red, 110lm
15 x Warmwhite (2800-3000K), 220lm
10 x Coldwhite (20000K lol?), 170lm
10 x 450nm Royal blue, 45lm
They are all cheap china leds from satisled (about 95$ for 160Watts). So i dont have a wavelength spectrum for the warmwhite and coldwhite, so i can only guess its kind of similar to other WW (more red) and CW(more blue).
Its all to be run @ 650mA with 3 Constant current sources. Due to the limitations of the 3 CCS I can use only about 68-69 LEDs of those 76, as I want to have a 10% buffer from max -as efficency decreases using more then 90% of power..
Which of those LEDs would you leave out?
Also as I have 3 CCS I can wire them up in groups like e.g. all blue and CW to one source and deep reds to be exclusive on another or i could make groups that would get switched on off in different stages.
Could you give me some good Ratios for 3 different stages with the LEDs I have? Then I could calculate myself what do use forwardvoltage wise.
My thought is using 9 of the blue and only 4 of the CW. Or less blue and more CW instead.
Can you give me some advice on what to do please?
