Oh I forgot to add you probably should buy some lenses too since it helps a lot with the light not going everywhere. You also want to ask them to switch out the leds, you don't want the all blues that normally come with that kit. You should go for some cool and some warm white leds. When you ask them to switch out the LEDs, make sure that the LEDs are solderless and that they match with the lenses you order (almost made that mistake). I tried to find the pics from when I had those LEDs running but I realized they are all on my old ipod which I have no idea where it is. I got the idea of using these leds from user RSS on terraforums and you can see his results with the same kit here:

On the last link he used a few types of leds, but I definitely recommend reading that thread. Good luck!
