I have just received my 30 metres of LED Strips which are 12V 5050 -60- WS2811. They use 14.4W per metre. I have attached them to 25mm conduit and will be attaching that below the guttering. My question is in relation to the wiring and the best way to connect to the LED strips and size. I will need approx 100m of wiring in total with 19 metres being the longest distance between a power source and Strip. The LED's are a 3 Wire setup so I was thinking of running 3 core 1.5mm flat insulated wire back to the garage where the 4 Power Supply Units and Basic LED Controller will be. There are 7 Sections/Channels with 10 strips in total. I have attached a layout to help visualise what I am trying to do. My Questions is: Is the 1.5mm wire good enough to go the distances I require so I don't lose voltage/signal etc and have I forgotten anything. Thanks in advance! Klaus.
