For my mega tree last year I used WS2801 pixels but this year I'm looking at replacing all the lights on the roof with RGB's (which are currently traditional green and red light zip tied together). I wouldn't think the pixels would be the best choice as they need to be supported and that would be an additional cost. I'm looking at probably getting about 50 5 meter strips. What does everyone recommend. I really don't want to pay over $20.00 per 5 meter strip. I'm also questioning what controller I would need to control all of these. My mega tree which is 12 strands runs off 1 p12r.
