Landscape Lighting
 
I attempted to add a 35W spotlight to my exiting landscape ligthing. I also replaced the 105W transformer with a 200W. The load before the spotlight was around 70 to 75W. After the spotlight was installed every other ligth in the system dimed. Current wiring is 16 gauge about 175-200 ft long. Will a larger gauge solve the diming problem or should I wire the system diffrenlty?

Check your voltage at the end of the line. You might want to do both, heavier wire and wire differently, 200' is a pretty long run

Will do. I've heard of using a T method or loop in wiring. What benefits do those types provide?

Check Voltage
 
The human eye cannot tell the difference when landscape lighting is running between 10.7 and 12 volts. The Utah outdoor lighting systems we install follow this rule and it has helped give us a range to work in.
