DIY led grow

That driver is an awesome deal. You end up with just as many (DC) wires as separate drivers but it is hard to find a very high efficiency, power factor corrected, 700mA driver for COBs.

Looks like a good driver. The only one available too, guess they don't show up on ebay much.

Looks like it'll run 4 like you said..plus at around low voltage levels.

Only thing bad is it's not dimmable so it comes down to is that how many watts you want at 700ma. 18$ looks a steal if it's real...lol

You can check future electronics to see how much it normally goes for. They seem to be the main distributor. The 200w ones I got weren't in stock and were basically made at the factory and shipped..took almost 2 months

The Meanwell HLG-185H-C700A will do the job and is dimmable, power factor corrected, very high efficiency, but setup for a single high voltage string. Cost $72, 3 in stock

I am not sure if the inventronics in the add is power factor corrected, not that it is a big deal but it says it takes 2.1A which is too high for a 160W driver.

Good catch on that one supra. Thinking about it and I wouldn't want to buy a driver without a link to a datasheet. The description is too vague on that sellers page.

Those multi channel drivers would be great for running these cxas..less voltage..less individual drivers....good idea

Here's a article I found reading up on drivers..inventronics biased but useful info

Couldn't find a whole lot of data on this driver, so hedging for the moment. Will try later this evening.

--I am intrigued by a multiple channel driver as well, particularly if it is like the 150U series which was 93.5% efficient. Do you just put a quality zeneer inline with a high voltage series?

But, have to see what circuitry a multichannel driver is using as well, because it may have issues too, especially with efficiency.

Going to read that last pdf you posted in a few....hope its good

I think because their constant current you don't need any sort of protection inline. I suppose you could for an added level of protection?

Worked on my ventilation a bit. Almost moved up to a 6" inline. Glad I didn't! Just shortened some ducting and changed my charcoal filter from a 4" x 12" to a 4" x 24"

Just about all the kinks worked out. Fans turned down to a nice powerful purr consuming about 20w..5w apiece.

Maintains a few degrees lower than ambient at 88*f on a 90*f + day at full draw. On a 70*f night it stays up at around 80*f......so much better temps.

At 300w draw the heatsink is literally cool to the touch...tempted to just run it around that power level. Drivers...everything cold..really does cruise at that power level

Plant health is also back quickly..leaving the light at 3' till I get the par meter

Ready to flower finally..maybe tomorrow day 1

Uvb 4hrs...flower initiator 6 minutes...12/12

This is going to be a hell of a show

Your panel looks bad-ass Posi..............like a god-damn alien space ship, no need to land in area51

Just wanting to get this correct positivity, you turn off all other LED's and just run the REDS for the 6 minutes ?
Why not run the flower power for the last 30 minutes of the light cycle, or are you trying to control stretch of the plant with the shorter time ?

Super nice build. I like it a lot.

i think those are 730nm flower initiator LEDs...

Kind of a funky light schedule realhigh..

The main light will be on all 12hrs. Main light has all the oslon hyper reds..14 of them running at 2.7w

The UVB will be on for 4 - 6 hours midcycle depending on how well they take to it. I've got two t5 bulbs instead of just one now so need to feel it out a little.

And the skinny bar I put my 730nm leds on will come on at the end of the 12hr cycle...right before lights out and a few minutes after. The 730nm leds change the phytochrome state and put the plant to sleep faster. Knocking a week or two off of flower.

I have two different reds...oslon hyper/deep red covering 640nm to 670nm with a peak at 656nm. That hits the chlorophyll peaks so their always on.

The other red..too much 730nm will stretch plants out so they are used just as a switch. Gotta remember the warm white leds have some 730nm in them so any additional will probably be too much.

Think that makes sense..lol..

I follow your work, so understanding it is a must and that is why I asked the question. Thanks for the info my friend.

How do you like your Oslons...? Not seeing many people incorporate them lately...i guess with the all 'conquering COB show' taking over.... mine are waiting to be installed...the LT-1974 SSL 80's

Do you remember the bin you used?

I put a oslon in my xml light right next to a luxeon deep red...the oslon is actually a little brighter visually...might just be a touch less deep red also..

I like them..I would of just used the luxeons but I was a bit worried about overheating. So oslons rated at 1a plus on a sinkpad made sense...the prolimatech pk3 that a few recommended was icing on the cake. Pk3 is really easy to work with..

Oslon hyper red on a sinkpad bin 3t4t. Couldn't find just a 4t batch. They have ledil Tina 2 70* reflectors on them since the only 3t4t bin oslons I could find were 150*

Red might not even be needed...lol. What the hell...
These cxas are bright and then some. But..for now..I like more 660nm in my spectrum

I'm curious what the specs are between the luxeons vs osram... Center peak both 645?, efficiency, output/ratings? You know pos?

Oslon ssl 150 hyper red datasheet....http://www.farnell.com/datasheets/1635541.pdf

Luxeon rebel es deep red datasheet....http://www.philipslumileds.com/uploads/265/DS68-pdf

Just know their supposed to be really close spec wise with the oslon 4t slightly better. Think supra had it calculated to within 1 or 2% of each other efficiency wise.

One day growth..holy sh!t. Didn't really flush them..just saturated with act and let them soak up the runoff. May have to just try casting tea the whole way..

Supercropped them a bit to open up the thick growth..running 320w right now. Trying to see if this can grow a small tree..

So..day 1 lights out. Hopefully the trigger makes this quick

plants running for peak, humans for dominant wavelenght.
Osram deep red here

I forget these little important bits of info..you can't even see the peak wavelength. Amazing
I did wonder what they meant by dominant..thanks
