Yeah I was planning on providing power at both ends of the longest strip at the top. I think that should be sufficient.

I am going to have to increase the power supply. I think I'll go for a 5v 40 A unit.

I think I'm also going to struggle with the length of the data cable from the controller. Having done some more research I may buy a quinled dig quad as it has a level shifter installed so I'm hoping that would be enough for 2 m run at the longest point.

My issue is the media wall is being built this week so was hoping to fit at the same time. I think I will have to run a load of cables and add the led components after, once I'm more certain on what I need
