I have a job lined up for next week and it will require 17-20w spots and 19-20w floods. Now the house is 4500sf first floor and the lights we be to seprate 500w systems front and back. The problem is with the back...it looks like it will be a 180' run around the pool deck with two lines splicing into that at 60 and 120' both of those go 50' and have 60w of lights on them. and power is on the side of the house so I know I will run out of voltage. I know this wont work...even with a 500w transformer Any ideas? I cant add a outlet in the back. I know I will loose 2-3 volts by the end of the line and have yellow light. Any Ideas?
