High Quality / Exactly Right

I finally made the leap to pro style lights this year after contemplating it for a few years. I'm glad I did. I measured my roof line using Google Earth and proceeded to order 150 feet of C7 stringer lights (3 X 50 ft), tabs, faceted LED bulbs, extra SPT-1 wire, and five male and female gilbert plugs. My first set up did take several hours but I things will go faster next year. All of the products were very high quality and work perfectly - I'm VERY pleased with Christmas Light Source! I'm glad I watched some videos on YouTube about installation as that was helpful. I should have ordered more gilbert plugs as the ability to make your own perfect custom extension cords quickly becomes an addition. Part of my hesitation to go this route was committing. I originally wanted white stringers with 6" spacing. Now that they're up on my house I know the green cord is fine regardless of your house exterior so I would not worry about wire color - just go with green as that's far more common. Second is that one foot (12") spacing is fine. I was thinking it would look a bit sparse on my house so I wanted 6" but it turns out that 12" is fine...and far easier to find. One change I might make is upping to C9 if I did it again. Either way, everything looks great. Christmas Light Source shipped my box from their home in Texas to my home in California quickly (ordered Sunday night arrived Thursday)! Everything was packed beautifully. All in, my experience with CLS has been excellent. Thank you CLS for making our home sparkle for the holidays! Good luck to your other customers!!
