I currently have a few of both 12VDC AND 5VDC strips of 2811 strips and experimenting with both of them. If I decide to use 5DVC strips (2811's) is it necessary to power up both ends of a 5V 5 meter strip with power at both ends? I would MUCH prefer to NOT run wires up to the top end if I don't have to.
The advantage of using 5VDC strips is that I possibly do not need to wire up the 'other' end at the top of the tree. Therefore I would only have wires at the bottom of the tree where maintenance is more practical. The disadvantage is that I need to purchase more P12R's as each 5VDC 2811 strip nearly requires one of the 12 outputs. Each of the 5VDC strips requires 150 of the 170 pixels. I am willing to purchase more P12R's as the only negative I see. 5VDC strips would have NO wires at the TOP of the strip. Easier to set up in the winter time and I would have control of each individual LED on the strip making for more beautiful and complex patterns. With 12VDC strips, I would have wires connecting strips together at the top of the tree as 12VDC strips can drive 3 strips. Wires connecting strips at the top of the tree would be a big mess. Not cool.
My question is whether or not the 5VDC strips require 5DVC power on both ends of a 5 meter strip?
Does this strip require power on both ends?
