I need to extend the wires on some of my bigW lights. I am running them through one of Alan's 2811DC 30 controllers on around 29V. They are a string of 200 Leds and I will run them as two banks. ie put one of the wires that used to come from the controller in the v+ and the other two in outputs 1 and 2. I need to extend them by say 10m. What sort of current do these strings draw so I can work out the voltage drop with different size cables. What sort of voltage drop do you think is acceptable. The strings say 10VA (10W) on the power transformer. The cables (wire) used measure around 0.6mm in diameter from memory (measured it a few days ago and getting old). Some sections of these lights are wired in series aren't they? How does that effect my calculations. Thanks for your help.
