What Did I do on the wiring?
1) I wired the LEDs in series for both white and blue
2) I wired the JBJ stock fans in series
3) I wired the white LED string onto 1000mA driver and the blue string onto 700mA.
4) I wired the outputs of the drivers with the fan outputs together in parallel
Tips for myself in future:
1) Use W40 or any kind of non-flammable oil during drilling and tapping to make life easier. I spent approximately 2.5 hours to drill and tapped 24 holes. I broke one of the drill bit but luckily my friend has one extra.
2) Polish your heatsink with Mothers Mag and Alum polish. I use a power drill with a cloth attached to it and add some polisher onto the cloth. I spent only about 20 minutes total including cleaning the heatsink after.
Soldering wasn’t my forte and I really suck at it! I need to use a better cable than that.
Enough said, here are the pictures:

Ghetto “project” BOX
All wired up, ready to fired up
All light up
1) How hot the heatsink can gets? The cable is rated 90C or 100C (one of them). Can this be a problem with melting if the temperature gets about 100C.
2) Any help with attaching the heatsink onto the JBJ NC12 hood? I can’t figure that out yet….I have two holes each side of the heatsink drilled and tap and I have 2 angle bracket attached to it right now. Can I use those + something else?
3) The 1000mA buckpuck run a little hot …almost too hot to touch…while the 700mA is not, what should I do?
4) When you guys saying you are adjusting the light to 50%, 60% or 70%, how can you tell from the potentiometer you have? LOL
5) How about those summer months when AC is not on?
