New style grow light mixed frequency

Considering a new design for a new grow light. Four 3590 COB, 2- 3500K, 2-5000K and 18 730nm LED diodes producing 200w at about 700mA, passive heat sinks, remote driver mount, 56% - 64% efficiency.

What do you think?

Im no expert but I think you might see more benefit using 3000k or 2700k for the far red than the 18 individuals. Unless you are planning to run them separately for the emmerson effect or whatever its called, after main lights shut off. Have you considered the 3000k 2530's that cutter has for $10 each in combination with some 4000k 3590's? Ive got some 5000k led strip lights and IMO they are borderline TOO blue....

thanks for the comments. right now I am trying to use what I got and make it work. I find the best ideas come from what you got and not what you can buy. thanks for the thoughts. I plan on running the red diodes along with the other frequencies, full time, to create a complete sun light indoors. I have mixed colors in the past to some pleasing effects, and I am wondering about using LED's to get the same outcome for a fixture that can be used for both veg and bloom. looking towards the future and experimenting to get there. peace

if your going to mix cobs ala cool white + warm white, then go the widest spread between the temps that's available.
ie 6500K plus 2700k instead of 5000K plus 3500K

I would skip the 730s. Warm white cobs do have a bit of far red light, not far off from the ratios found in sunlight,
especially with the warmer temps (3000k, 2700k) I usually let my Flower Initiator just run a little bit during the day cycle for a little bit extra while deep in flowering.

Will the 730nm induce stretching if left on?

Yes but that can be a good thing too when handled properly.

When I start building after the prototype that is excellent idea. Peace
