Has anyone used DB or DD bin Cree CXB3590?

Hey Coolj!

1. The large cobs like CXB3070 / 3590 or Vero29 should fade the Kessil things loose.
2. If you add 12 xte's to your cobs you will lost a lot of effiency. The DD bin/36v is up to 74% eff. @700mA, but the xte's are only <50% @350mA. The more mono's you add the more decreases the efficiency!
3. If you still want to add some mono's, you should take light blue 465-485nmnm and cyan 495-515nm for a bad ass vegging light, because the cobs has more than enough royal blue(peak), but is lower on light blue/cyan range/460-520nm. But I would only add max. 2+2 to each cob.

If you really want to have kick-ass vegging light, omit the Mono's and take more Cobs 4000 / 5000K and lower current to 350-700mA.
No need to add mono's, because the 4k/5k spectrum works awesome for vegging!

whats the difference with the BIN codes in general is DD better (newer rev?) than DC DB DA, etc?

I was reading this thread and what you just said hit me. thanks more photons, not more power. I am finalizing my beg light and that just helped the most.

I wondering for vegging if youd be better with straight 5000k 3590s, or 3000k 6500k alternating... That would give more reds and blues and a little less green/yellow.... Ive got a LED strip light that is single 3w diodes with 6500k, 2700k, 660 red repeating and it works very well for growing houseplants!

Screenshot (210).png Screenshot (210).png Check this out: It looks like a ammo box. Good idea for an easy to modify design. That $1199 would buy a lot of COBs and drivers. This guy's design has an independent driver for each COB.
