Hi fellow decorators! I'm new to RGB / LED lighting this year and a have been doing some research and planning for the last month and I am ready to pull the trigger on obtaining my lights and controller(s) (I know, I'm starting WAY LATER than I should be!) and I would welcome any input / suggestions / corrections on logic that any one can provide. First off, I've sketched out my plan and come up with the following: LED RGB strip lighting: 8 windows Garage Door Frame Front Door Frame Roof lines RGB "bullet" pixels: 4 - 50 pixel snowflakes over the garage door 1 - 180 pixel star above the garage roof Based on my measurements and calculations (as shown in the attached layout image and spreadsheet), I believe this works out to: approx. 77 meters of LED RGB strip lighting (just under 16 5m sections) approx. 400 "bullet" pixels I plan on on using 12v lighting and decided on the following key items to power the lighting / system: One 16 output controller: Falcon F16v2, PixLite 16 MkII or the brand-spankin' new HinksPix 16 (LINK) (3) 12v 350w power supplies: Something from Ray Wu or Amazon (this seems to have good reviews (eTopxizu 12v 30a Dc Universal Regulated Switching Power Supply 360w 5m DC12V WS2811 150LEDs (10pixes/m) led digital strip from Ray Wu (LINK) 18AWG wire 100pcs/string DC12V 12mm WS2811 addressable RGB led smart pixel node from Ray Wu (LINK) Based on my calculations, it looks like I'll working with about 3500 channels and 920 watts. It looks like I'll need to break the display up into about 11 outputs (each plan output group is denoted with the yellow boxes / orange text in the below diagram) on the controller and do power injection for some (all?) of the runs. I plan on trying to centrally locate the controller and PSU (shown as "C" and "P" on the attached diagram) and use CAT 5 for data cables and 18/16/14 gauge 2-core wire for the power injection cables. I'm working to get my head around power injection and will draw up a diagram for how I plan on making it work and will reply back with my plan for people to laugh at ( ). In the meantime, I would welcome any input / suggestions / correction any of you wonderful folks have! Thanks in advance and Happy Holidays!
