DIY LED Hood: Prebuild Thoughts...

[GMGQ]

So instead of jumping into the big LED hood build, I figured I'd do a small scale project first.

I want to build a refugium LED light with 6 LEDs:

4 x Cree XP-G CW (3W, max drive = 1500mA, forward voltage = 3.0 @ 700mA)
2 x Cree XP-E RB (3W, max drive = 1000mA, forward voltage = 3.4 @ 700mA)

I plan on using a buck puck with a potentiometer. Will this one work?

If so, what power supply would I need for it to drive the 6 above LEDs? (24V, 1000mA as per the buck puck?).

And I assume I should wire them in series?

Thanks guys.
