LED grow lights

Does anyone have any experience with Cree CXB3590 cob?
I want to make a bar using some of these for running mums and cuttings under.
Any suggestion on which spectrum to use
I like the 2700K, but I think they r probably better for flowering.
I'll use a bit of t5 with the LEDs to add UV.

## I know these chips rn't top of the pile anymore, but these r what cutters is offering in the d.I.y. kit.
They put out 1.9 umol so I'll take that
Any suggestion on the 2.7-3K spectra for veg?

Their 1.7K( bridgelux)looks cool for bloom only.

I have had them Vlad.. i had 3500k around 90w cobs.. great light but I used them in flower.. I stuffed up and swapped over for QBs (which I've advised others to use . Sorry). Wish I'd kept them, instead of watching mate now get harvests I want, lol.. don't know if any of that helps you though, lol.
 
Hi Vlad,

I have some of them. If you take the latest binning (DB)then they are still top range ;)

I personally would go for the 3500K spectrum. With these you can grow and flower, has enough blue spectrum and its the better priced cob 2700k or 3000k are usally more expensive or less output.

I was looking here, as a replacement of my old panel.

dimmable optic 2 gen4

Or 2nd choice rebuilding my old panel, as I would like to get it wired properly, as the man who made it must had been ill. :( No comercial panel., but working for 5 years now. Just so I was cleaning it i saw the mess....
