[QUOTE="Saratj1"]All parts availible from eBay I would post links to everything but I'm using the app and it takes a while. Just search my part listings an find the cheapest or best for the money.
9x 10w hybrid led
power supply that is rated at 36v 3000mA~ $40
1x potentiometer (dimmer) ~ $10
molex power supply ~$12
2x 120mm computer fans ~$12
1x three prong power cord $10
1x CPU thermal paste ~ $5
1x large heatsink aluminum ~$60
Misc wiring and soldering supplies. ~$20
this setup will be 90w of led
, if you want 120w you could get 3 more emitters, and get a power supply that was rated at 36v 4000mA or 48v 3000mA
With a 36v 3000mA power supply you will run 3 rows of three emitters wired in series.
With a 36v 4000mA power supply you will run 4 rows of 3 emitters in series.
With a 48v 3000mA power supply you will run 3 rows of 4 emitters in a series.
If you have any questions feel free to ask.
You will end up with something like this-
