I don't know how to build one. Or where or what parts to get.

We can help you with all of that here. It might seem overwhelming at first but once you get the parts in hand it is honestly very simple. Building it at least. All the math I still struggle with but I know everything is golden from everyone's help.

I got a 400w light built for $700, that includes shipping too, and expecting 1gpw at least on this new system. Doubling my yield and decreasing my electric use in half. Only requires a simple box fan to keep the lights cool, which was already in the grow area for air circulation. No ventilation and heat to deal with. Well there is heat, just not near as much.

It's worth it

Me too.. I would love a LED for dummies thread. I've never used LEDs but I'm ready to attempt a build.

@ Airwalker.. Ive seen a few guys using the T8's led home depot bulbs ...they just swapped the fluorescents to LEDs on old fixtures.

400w of light is 400w of heat no matter how you slice it your gonna need adequate ventilation just cause the led run cooler it's still the same energy pumping in there

No not completely true.

400 watt heater can have many efficiencies for heat production. But it's purpose is heat so not complicated and thus its main byproduct from the electricity is heat.

400 watt light will not produce the same heat as a 400 watt heater. The technology of incandescent lights are very close to some radiator heaters and thus have similar heat production. 400 watts of cobs run at 25 watts each will not come close to a 400 watt heater because of soft ran cobs are awesomely efficient

@SupraSPL can help with how much heat my 400w 8x cxb3070 setup dissapates, he knows the math.

Might give you an idea for a 400w system like mine. I don't have the best cobs which are the cxb3590s, but I have the second best with the cxb3070s. And at half the cost it's nice for a first time setup like you or I.

So I have been reading a lot here and have kind of an idea what's what.. Please correct any mid information.

Cobs - chips on board - There are 2 kinds that are suitable ? Vero 29 and Cree ? They come in 3, 5 and ten watt diodes???
Cob holders - simply hold the cob light in place.
Drivers ( mean well) seem to be top of the line? Each driver can handle 2 Cobs?

Heat Sink- Aluminum piece that spreads heat evenly amongst the cobs with a fan??

not instantly sure but its still all energy is converted to heat and you got to deal with that

This argument had been discussed so much and i didn't want to believe at first either but the people who know there shit know this even the misses (physics major)explained to me that it still the same energy flowing

I think people get confused with watt dissipated and heat dissipated.

The more efficient a circuit is the less resistant it is. Resistance to electricity adds heat. Otherwise the very efficient copper wire running through our walls would produce the amount of heat in them same to a toaster or electric oven that was being fed by the wires.

I'll find more accurate data. But a light uses energy to produce light or photons as its byproduct. The higher effiency the more light it produces from less resistance and thus less heat.

Give me a while to find a better articulated explanation

$700?!?!?
The go green 400w cob LED is only $450. I thought by buildin you meant like $100,200?

No ..vegging ... But I know those tubes would kick the crap out of those blurple UFO for any phase of growing. My buddy used to grow with those UFOs ..That's why I thought Leds were garbage until he upgraded to a blackstar.

email jerry at kingbrite with what you're making and he will tell you want you need and send you a paypal bill.
Then you need a heatsink and some stuff from RadioShack

I don't know what kind of parts and at what efficiency this go green runs their systems. But my cree cxb3070s cost me 40$ each, and I used eight to cover my 12sqft of flowering.

I had two lights before hand, a 600w HPS, and a Chinese made full spectrum Apollo Purple Sun 384w, 180w actual draw, so 800w total. And that 200w Chinese cob led got me an ounce less then my 600w HPS.

I'm looking at 1gpw minimum with my scrog and 400w DIY cob led fixture, nothing I could imagine with HIDs.

your on to something but the wires aren't using the energy they are just moving it big difference. The other good point was that we have more efficient lighting which means we use less energy to obtain the photons from the light the key is saturating the area with more light doesn't equal more light being used
edit:sorry misread the wire thing
