make sure you are always going from the positive on the ldd to the positive of the first led then out the neg to the next positive and so on through each string. also make sure your greens and reds can take 1000 mamps. mine are 700 m amp max. so you may want to change to a 700 max mamp ldd for that string. other than that and the dimming issue above it looks like a promising light set up. i would be very interested int he par numbers and how you like the color of the light.
