Cree Xlamp Grow-Light Schematic Design (Wanted)

[Weezard]

hey weez,

how much would an array of those 660s be with say 10 or 12 in each? or would it need to be less, like 6 LEDs because of power?

I'm using 5 now.
4 reds, 1 blue and I'm only pushing the reds to 12W.
Using a 10" by 12" cake pan as a reflector, I still need to keep it at least 3" off the tops.
That's a picture of this light on my profile.
From the results with WW and AK47, I can't see the need for more power.
(Yeah, I know, blasphemy!)

I'm pretty sure that the 660nm. LEDs make the difference and allow me to use less than 100W. and still get hard, fat colas.
(Though I may add another blue for shorter internodes)

I think they cost $31 ea for the reds and $36 for the blue.
Don't quote me on the price, it's been a while, and grey ram being what it is...
Suggest you goto Mouser.com and do a search for LZ1* for a current price.


The 15W. Ledengins are easy to mount, easy to wire. You can turn out a finished light in, say, 2 hours.

Lemme know if I can help.
Weeze

Their time is now :) Yes I've seen the extraordinarily overpriced products being offered by businesses. Not worth the money if you can use a soldering kit, imo. I can solder, but I'm no engineer, so, I'm asking for help in creating a circuit design that balances low cost, simplicity of construction and high efficiency.
