LED Group buy!

Ok So I got 14 different ones connected to the 60W. No heatsink to mount them on so it's a little hard to see them all to make a comparison. They are way bright, even fully dimmed with these drivers. It's hard to type right now because I have spots from staring at them for 5 sec to see if I can tell the difference.
I don't see any difference from the blues at this point though. Need to go buy some thermal epoxy and see if I can mount these to something.

I through it together real fast to show people as they come to pick them up, in case they have questions. Also to test the difference between the blue and the super blue. Using extra LED's I ordered to see the difference in the whites and blues.
When they are dimmed they don't heat up at all, but if I turn them up they get hot fast. Not running them for more than 30sec at a time.
Crit, when you built your did you use the blue and the super blue? If so can you tell the difference?
When I look at the cree Royal blue vs blue, its easy to tell the difference, and I figured these would be the same.

Derek,
What are the specs on the 60W Drivers?
I think the 30W Drivers are the wrong ones. The ones I picked up from you say: DC OUTPUT:60-100V 320mA+-5% (20-30) x 1W
Shouldn't they be 700mA?
I tried to wire up my first bank, but all the do is flash every three seconds. Don't think there is enough current to drive 10 LEDs in a series.
Since I don't have a wiring guide here's how I wired my LED's up:
On one side of LED Driver, a single pair of whites. I connected these to 110V AC.
On the other side of the LED dirver, a pair of white and a red and black. I connected up the RED to the + on my first LED, then the BLACK to the - on my last (string of 10) LED. The white pair, I connected to pins 2 & 3 of the potentiometer.

Also, Gale just brought this to my attention. It looks like some of the Labels on the drivers are printed backwards.
Just to clarify, The Red cable is your + to your LED, the Black cable is your - to your LED.
On the other side of the driver is 2 white cables, I plugged the one thats at the same height of the red cable on the oposite side into AC+ and the other one into AC-, I don't think that matters though.
For the dimmer circuit, the white above the red is Dim+ (it connects to the center posts on the Pot). the other cable above the black is the Dim-, it connects to one of the other posts (doesnt matter, will just change which way you turn it to dim it).
