Multichip LED panels

BygonEra · Jun 15, 2013

I found a DIY video for making a 100-200 watt LED panel for an aquarium, and it seems much cheaper to buy all the parts to make this rather than buy a grow light with the same amount of wattage. Does anyone know if these can be used effectively as grow lights? And I know light spectrum makes a huge difference and I don't really know much about that... but concept wise I don't know why it wouldn't work.

Added up the costs:

LED multichip - $35
Heatsink + fan - $10
Driver - $30
Thermal adhesive - $5

Soo... around $80? I think?

Has anyone tried this?

use some hours to search in here, many do DIY LEDs, also use a few hours to research light spectrums a bit, its not that simple and a lot of debating on what is the best

here is a link to a nice pages where you can see the different spectrums and where they peak aso

http://www.buildmyled.com/custom-led-strip/

newest panels I have seen online carrie a lot of white`s in em, seem like the white LEDs are the new black so to speak, I also have some 6500K in my panel I use to flower with, seem to do a big different since its not only blue/red the plants need

beside whites it also seems like red and fare red (630-660nm) is important, specially in flowering

based on all the hours of reading/reaching I done so fare, I would probably make em with a mix of 6500/2700K (ratio depending on grow phase) with a few 660nm mixed in, Etc. 1x6500K 3x2700k and 1x 660nm ratio (for flowering) just one way, many opinions here, agin as I said. do a lot of research, google is a great tool

The 'problems' with multichips (and I do like them < 30w) include; you need 3+, so cost multiplies + they are a point source light

Having vg results with HOT5s, I am moving toward T8 LED tubes $35 @23w/4ft. Of course a 'fixture' is needed, but it's a simple DIY, or buy one and bypass the internal ballasts. Super easy to add more as needed, or as $$$ is available

If they offered a PLL equivalent, I'd be all over those tubes

. I like PLLs because they can pack up to 55w into less than 23", which is just the right size for my tent.

I've been toying with something similar, in theory. I want LEDs that would only be for flowering, so would 6500k be beneficial, or would it be better to go lower, like 5000k? So perhaps 1x6500k, 3x2700k, 1x660nm?

According to the Buildmyled site, that ratio would give:

Blue (400 – 499nm)9%
Green (500 – 599nm)32%
Red (600 – 699nm)56%
Far Red (700 – 750nm)3%

Substituting the 6500k for 5000k would move the Blue up to 10% and the Red down to 54%. Not much difference, obviously, but could be when it comes to flowering. Then again, 4000k in place of 6500k or 5000k would net the following:

Blue (400 – 499nm)7%
Green (500 – 599nm)31%
Red (600 – 699nm)58%
Far Red (700 – 750nm)4%

Suggestions?

I think any of them will work, as you said, not much difference, was told the 6500K was the most effective of the white`s but Im sure thats also minimal and all would grow you some Bud`s Im sure

brotherjericho · Jun 15, 2013

Come to think of it, 6500k would probably be best for my grow space because I like to control height. The extra blue might be enough to keep stretch more manageable. It least the hypothesis works in my head.

it's most effective , as it's more blue ( white LED are blue LED with phosphor coating )

there not minimal, cool whites put out more light then warm whites / neutral whites
