I did a small lighting job, about 30 lights and 10 spots. Customer wanted 5 spot lights in this one flower bed that is located about 60 feet from the transformer then over the next 100 feet 5 50watt spots spaced evenly apart. The lights are malibu and the transformer is a 300 watt malibu. (it is all the customer wanted to pay for) i used 10/2 gadgue wire and they are dim. is there anything else i can do to get full power out of the lights?
