hey all,
Firstly I'd like to thank the pioneers here - without growmau5 alone I'd never even attempt this.
I decided to take the leap and replace my hps with a bunch of cree cxb3590's. I've been running 1-2 600w hps and struggle dumping the heat especially in the warm weather. Creating less heat per watt alone had me sold on the COB technology.
My goal was to create a modular COB arrray that can replace 600-1800w hps depending on the number of panels used. I decided to build 4 separate panels each housing 6 cxb3590. The citizen and bridgelux products were not on my radar when I made the design - I may kick myself over that one later but my knowledge of cobs is a little lacking.
Here's the parts I used:
24@ cree cxb3590 3500k cd bin
4@ meanwell hlg320 1400b
150mm kingbrite heat sinks
Ideal holders / adapters, kingbrite reflectors
~70ft 3/4x3/4x1/8 6061 aluminum angle
Firstly, the cobs and sinks:
1/2 of an array mocked up:
Frame and wiring done (sorry for the quick jump - I was entrenched in my work)
And into the tent:
Well that's two arrays completed - the other two are framed out but need all electrical work done.
When finishing those two I'll be changing the ac side of the connection a little - I'm planning to wire a nema locking receptical on the driver pigtail vs the direct soldered connection to the cord. I believe this will be a cleaner solution.
I'm also going to add a switch in the dimming circuit.
A couple things I learned -
-While a stronger option the 6061 aluminum has a rounded inside corner.
-mount cobs to heatsink after the array/framework is completed.
-drilling and cutting aluminum in your house will make your wife crazy.
-these things are heavy! - I might have to beef up my tent.
Any tips on the transition from hps? As you can see I tossed these over a hps grow in progress.

what size are they?
