Cob light color choices

[MadButcher]

If you would build a light which you are planning to use for full cycle growing, what of these color temps would you pick??
White @6000-6500k?
Warm white @3000-3500k?
Full spectrum 380-840nm?

Or a combination of either one?

Please tell me which you would choose and why.
I'm planning to build something that I've not seen here yet in this form, so sceptics are not needed.

Either all spectrum or a mixture of 3500 + 6000k... I would personally use 4000k if available..

 

[MadButcher]

Why no 3500 , 4000 or 5000k? Just wondering... Either all spectrum or a mixture of 3200 +6000k... I would personally use 4000k if available..

There are only these 3 kinds. 3500 are there, sorry, had my numbers buggered

Care to elaborate? Or is curiosity just another form of skepticism now?

No, it's not.
There really are only those 3 kinds available and I just want to hear what people think would be the best combination.

So just to be clear, "Warm white @3000-3500k" is the option you have, and not a choice between 3000k, 3200k, 3500k etc?

Yes. That's how the colors are listed. And that's why I'm almost thinking full spectrum

There are a couple DIY threads here/ Check out Quantum Boards, which have greater potential than CoBs

Thanks, I'm aware of those. But if that is what I wanted to work with, I would have asked something about those.

I can't figure this out. Doesn't seem to matter what kind of light a guy wants to use and inquires about , there's always rightaway somebody recommending something completely different...

Sorry, been at leds from the beginning. I have 3 CoB lights and one ML SPYDR 600 which is like QBs on steroids, covers 4 x 4 @ 360w all monos, but I mixed CW/NW/WW + 450 and 630. I like them all, but the SPYDR coverage is a lot more uniform

I am totally sold on QBoards as soon as I can find someone selling them.

So Im assuming they are all dirt cheap chinese crap? "Full spectrum" seems pretty vague without an SPD to go with it, no?

I don't know.
That wasn't the question either.


Thanks @HydoDan for the input

 

[CobKits]

3500k 80 cri

 

[MadButcher]

3500k 80 cri

Cool, thanks. Although these say cri85 but I think that should do too. Or not?

 

[CobKits]

should work fine. lights sound cheap and unreliable in absence of a spec but thats been said already

Yes, I'm aware of that. Thanks

 

[Shugglet]

Why can't you divulge more information? Why not just link to the leds? Or what your plans are?

I can assure you no one is going to swoop in and buy these out from under you lol...

I mix 3500k 5000k and full spectrum for fantastic results. I use same for veg and bloom. Thick stalks healthy plants large flowers and aromatic as well. I tried straight cxb but not best results but quite good adding full spectrum completed the cycle. Additional red and blue are necessary for healthy plants based on research by industry.

All cobs are made in China new cobs out are full spectrum rated at 10w to 500w based on current draw up to 8A. I have some of these just as good as cree and others in construction and luminance. Industry uses full spectrum only small groups use white only lights with no real coloration except color correction factors cri and temperatures kelvin lacking in many spectrum. You would need to use 2700k to 6500k to get full spectrum like a single cob.
