Voltage Drop Calculations for 12 Volt Outdoor Lighting Systems

I bought a new 300 watt low voltage transformer that is attached to about 175 feet of wire. The lights that I have attached, although significantly less than the indicated 300, drop off drastically in brightness at about the 100 foot mark. What need I do?

You need to split the lighting load into several home run wires back to the transformer or you can run a continous loop wire from the end of the run back to the transformer to boost your voltage. In other words, feed from both ends! Please review our information page on low voltage lighting designs and voltage calculations.
