how did you end up with ab bins?
also how can you tell what binning you get? by looking at the chiP? mine just say cree...

[StevenJennings]

I just wanna say hell yeah man, amd im only at the end of page 1. Your builds are a hell of a lot cleaner than mine. Ill keep readimg before i ask any questions. Lol

[StevenJennings]

It should def say what bin you are gettimg on the site you get em from holmes. They are not located on the led itself.

Welcome Steven!

I'm dialing out the new grow operation (3d take), and boy... it takes time and patience to "master" the scenario!

I will be using the COBs on active CPU heatsinks to supplement the 400W HPS, to reach 600W. As the driver is dimmable, I'll be adjusting the LED intensity depending on temperature by using mycodo.

Will post pics of them, due to the purpose I'm going to deploy them, the binning no longer worries me too much.

I sourced them from Mouser, this is on the invoice:

Mouser REF: Manufacturer. N.o: Desc.:
941-CXA30700N00Z230F CXA3070-0000-000N00Z230F High Power LED Warm White, 3000K 8646lm, 1.9A, 80CRI
TARIC:8541401000 ECCN:EAR99 COO:CN

Points to Z2?

BTW, loved your barrel build! with suitable low power LEDs would make a great "Mother Keeping Capsule"! Though I think would be even greater for those wanting to flower stealthy using COB w/ external heatsink as you designed!

[StevenJennings]

Thanks man. I get those barrels from work and had been thinking about sticking a few in the garage or something after i make it a little more stealth. Hide wires, and the light being emitted. Man i got all these drivers laying around to power a cob at anywhere from 1050 to 1750 ma and had id known id be setting up more stuff i prob wouldve just went for the more costly driver. Ill be following your grows man. When i rrach 50 posts ill start a thread or two with my closet and other past grows. I will say that im a firm believer in the reds royal blue and various whites. Since i added my bar ive noticed less stretch and frostier content. Not tht the 3500k cobs dont produce quality. I can def tell a difference. I been thinking about doing a deep red puck or something to see if the emerson effect is substantial for me.

Do you use hoods for the COBs? Are they a must?

I definitely noticed a difference when I added reds. All ladies did show clear preference for the WW XM-Ls, positioning their colas underneath.

Problem with LEDs is the sativas I'm keen on all need lots of UV to properly develop their nugs, that's the reason I went back to HPS as main light source.

Don't get me wrong, they did yield really aromatic, and potent (7 over 10) nugs, with the HML, I got my gram per watt, but it was clear the nugs weren't fully developed. Again, I was using 10W LEDs, not COBs.

Something is clear for me at least; coco + LEDs produce the most aromatic nugs.
