The house you see in the picture has 600 C9 lights on the house, 90’ of lit garland, and 300’ of mini lights all running on just one outlet. The reason this can be done is because everything is LED and nothing is incandescent. The 600 C9 LED lights use about 2.7 amps of power but the same incandescent version of the bulbs would use 42 amps. That is a big difference. LED is the future of holiday lights. LED does cost more but you get a great return on your investment and much better longevity.
