So I had a cob burn out due to improper mounting. Got a little carried away with the replacement. Wanted to see if I could cool this with the heatsink I had.

none are running over 20 watts ATM.
It's really bright though. You can barely see the light my blurple light puts out lol.

I'm curious what the mistake was, specifically. Kinda makes me nervous
The plants look great btw

Didn't mount it well enough to the heat sink so half of it popped off and burnt out.

It's cool I ended up with twice as much light and about 5% more efficiency.

Thanks bass. Was waiting on a bigger build so I had the brand new cobs sitting around. Doing some spectrum experimentation figure they're more likely to mix close together. Plus, just means I can buy better cobs for my bigger build lol. I do have some of the 90 cri cxbs in there right now. The spectrum was too tempting.

I have several different cobs here, so I will never know which is responsible or not for the outcome from my grows.
I am interested in seeing how high CRI compares to 80 and or 70 cri grows

Well I now have them more or less clustered and have
3 X 80cri 3000k crees
2 X 93cri 3000k Crees and
4x 80 cri 4000k veros. I'm hoping the spectrums mix the way I have it arranged.

I have cobs on 8"x8" Heatsinks. Right now a pair per heatsink, but I am going to redo it soon and might change it

Hey bass!
How thick is the base of your 8x8 hs?

.375" or 9.5mm

littlejacob · Feb 6, 2016

Wow that is a very thick base (man...lol)...almost 2 time mine...5mm!
So I guess one of those could run a cxb3590 @1400mA passively or 3 with a fan!

I ran 2 passive for a whole day by accident as I forgot to add a fan on it.
It wsnt super hot, but it was very warm.

I run these one per HS and they are super quiet and keep HS cool

Nice pic! I notice the legacy HID sockets hanging on the side. After discovering DIY COBing, my HID fixtures are now gathering dust as well. So please clarify a few details of your build. So you have 5” pieces of the 4.9” HSUSA heatsink, with a CXB3590 on each one driven at 50 watts. I am assuming you have a fan on each one? A picture of the top would really help. I like to see how other guys put their light bars together. Also, as a side question, please explain your watering scheme. Thanks.

So added 4K Vero spectrum seems to have shifted nug structure in flower. Starting to kick out completely new calyx growth on the sides of the colas. May just be the extra light though.

up till this pint they stayed pretty rounded/flush.
