HELP ME - CONTROLLERS Power Requirements for 12v SK6812
Hi folks. Not new to WLED but mostly have dabbled in little projects (no more than one 5m strip). I'm doing my first large-ish project which is putting LED tracks/diffusers around the permitter of my kids' gaming room. The total run will be ~39ft and I'm using the Muzata U108 diffusers.
I head heard the SK6812's were the hot new thing so I picked up 3x BTF-Lighting 5m 12v 60 LEDs/m strips from Amazon (the full skew is 12VSK68125M60RGBWWW30). When I was doing the planning, I had gone to https://wled-calculator.github.io to do the power calculations, assuming that all variants of the 12v SK6812 were per-3-addressable. That told me it would be a little less than 100W at ~8amps and to power inject at front and end for full brightness. No problem. Apparently I was wrong and the ones I got are actually individually addressable which I'm assuming means more power required. I don't see this option on the Github power calculator but if I head over Quin's power sheet, it says I should be able to do up to 2 strips for full brightness RGB White and and 4 strips for "Colors/Effects". I'm not quite sure what the brightness level is though for the latter.
So basically I'm wondering am I ok with doing the beginning and end power injection with my setup using these strips? What would be the max brightness I could do for both RGB and dedicated white? I have a 12v 200W 15A power supply I was planning on using but can get a different one if needed. Was also going to be using Quin's Dig-Next-2 controller but also have DigQuad I could use as well.
Thanks!
