Mr.Christmas/Gilrock,
Sean had posted somewhere that he used 4m weatherproofed 1809's 12v, 30 led per meter. I like that spacing and the individual control over each led. Just trying to find that particular one.

The ones I've always ordered are a direct link from the DLA Wiki for smart strings.

This is for 4meters, the max length supported by DLA, but I would just ask Ray to make them 5 meters and shortened them as needed.
If you want custom lengths and pigtails, I've found him to be willing and the extra cost is probably less than your own time.
