Just hoping that someone can comment on my shopping list. I think I have worked out the components I need.
I intend to build a 2.5m 12 branch 2D mega tree using conduit and WS2812B LED strip. (may expand to 16 branches)
6 x WS2812B LED Strip 5mtr

12 x pigtails

6 x T - cables for power injection

2 x 5v 400w power supplies
http://www.aliexpress.com/store/product/5V-400W-rain-proof-switch-mode-Power-Supply-AC120V-or-AC230V-input-DC5V-output/701799_1750594048.html
1 x ECG-P2-2 controller
http://www.j1sys.com/ecg-p2/
I have chosen 2 x 400 watt power supplies given the pixel strings are 30LED/m = 14.4w
Thus 14.4 x 2.5 x 12 = 432. To be safe use only 80% capacity so I would need a 540w power supply.
It would seem better to get 2 x 400w and I could add another 4 strings and go to 16 branches if I wanted.
The controller, I have 30x2.5x12 = 900 pixels / 170 = 6 universes required.
The P2 should give me 2 connectors with the capacity for 4 universes each, again should be OK for this project and again able to go to 16 should I wish to expand.
I also considered the Pixelite 4, this would seem an attractive option, but costs a little more.
Is my logic OK, or is there an error in my thinking?
I have seen the odd comment that the P2 can be a little sluggish? Am I better with the Pixelite 4?
Any suggestions appreciated.
Daryl.
