I just finished three of these for my 5x5 tent.

Each one has:
2 x cxb3590 3000k 72v
- powered by HLG-120H-C1050A
1 x cxb3590 3000k 36v
- powered by HLN-80H-42A
3 x Cpu cooler fans
- powered by LPV-20-12
AC inlets and outlets.
All cobs mounted on Alpine Arctic 64 Plus cpu coolers with Ideal holders and then fixed using cpu cooler motherboard brackets inside of a vinyl fence post (vinyl post idea borrowed from @SomeGuy if I'm not mistaken).
They use about 250w each for a total of 750.

How do you work inside the vinyl fence post? Do you split the post and after getting everything mounted, tape or glue it back together?

Vinyl fence post from Lowes http://m.lowes.com/pd/Gatehouse-Arborley-White-Vinyl-Fence-Post-Common-96-in-Actual-96-in/4009495

Used chop saw and dremel tool to cut it up.

Again I got the fence post idea from @SomeGuy. I simply liked the look better than the fully exposed look.

This excercise kinda freed my mind a little as wacky as that may sound.

Btw, I also got a nice amount of helpful info from @SupraSPL and a couple others.

caretak3r has a photo of one that he built using the vinyl fence post on the first page of this thread. I like caretak3r's idea of running an exhaust fan at one end and an intake fan at the other end of the fence post, but I don't see how to fit the parts inside the fence post without cutting it open first and then taping it back together but in the pictures shown, I don't see where the post has been split open.

I have the 4.9inch from heatsink usa. Then bought the 5 inch fence post from homedepot. Cut it to length then in half. I have it on top to channel air flow.

The inside work was done through the end holes and the large fan holes on the top.
I will admit that it was a big time pain, but that's just because it was a first pass effort and I wasn't really that smart about it.
Next time I would take measurements from these and then do the difficult parts outside of the vinyl. I would then slide the whole internal assembly into place and add bolts where needed.

I did the fence post method as well. It's really clean. I found the same thing, once I knew what I was doing on the first one, assembling the others was a breeze.

Finally got the time to throw up my new light i built. Designed to cover a 3x3 area but really covers about 3.5'x3.5' with (4) 72v cxb3590 3000k 80cri driven by two hlg120hc1050 dissipating about 75w per cob and ~49% efficient. Actively cooled by 4 artic f12 120mm fans. Heatsinksusa with the 5.375 profile by 6". I am slowly making the switch and driving them a little harder to lower upfront cost. I like that i can later swap drivers and build a more efficent light as i can afford more cobs.

Plants are cuttings from a pack of gods ak47 in rdwc. GH base nutes. I think i am going to shatter my best g/watt. Heres a shot of the 1st gods ak47 with a couple weeks to go in organic super soil. And the dwc roots, super healthy, they love twmps in the 60s, absolutely blowing up 2nd week of flower.

@cdgmoney250 very nice set up you should look into running variable light cycles half on half off with overlapping times it's old tech but people were claiming 1gpw for every 30 days of flowering the real way to calculate gpw that's like 2.5 in today's standards something you may want to look into

That would definitely apply if he couldn't dim his Lights. Dimming would not "waste" light pushing past the light saturation threshold but would give him better system efficiency. Just food for thought as there is a different variable in the led equation.

Big kapton fan :) too easy!
Last drill attempt broke 3 bits...



I can drill holes to put wires through, but not to screw in the cobs lol. I crack myself up! The cab it's in is blinding. Super stoked off this build :)

My HS looks terrible with tape everywhere lol.
My 2nd hole drill bit broke and I just bought Kapton tape .

you guys are making me want to do a video tutorial on tapping..lol. I would if I knew how, no video skills. Its faster than kapton once you get it down

lube, lube, and lube. lube the drill bit, the tap, sh@t put a drop in the hole before you tap. Back out when you feel resistance...

Glad you guys are getting it done anyway. That light you made should grow some fire @Waiks

$3 and enough to last a really really long time...
