2021 Xmas Light Replacement

After thinking about it for 20 years, we made the commitment to replace the light strings on our house with customized C9 LED (9-inch spacing) and C7 LED (12-inch spacing) strings. We have the C9 strings cut and installed. They look fabulous. We have the C7 strings for around windows and doors cut but ran out of Gilbert plugs(ordered more this morning). We are very pleased with the quality of the light bulbs, wiring(went with SPT-2 and am impressed with the quality - well worth the extra cost) and hardware. We also decided to add the rubber o-rings for rain and snow in Wyoming - glad we did. Ordering and receiving the lights, cords and accessories with Christmas Light Source has been seamless and timely. We went with the Gilbert plugs including the inline plugs and have greatly reduced the number of extension cords. We would highly recommend Christmas Light Source. Will send photos when we are finished. We wish everyone a Very Merry Christmas.

Good job

CHELSEA M. (Edmond, OK)

My husband and I are complete newbies at installing Christmas lights and this spool made it easy to cut our lights to the perfect length for our house. Shipment was VERY fast. Excited for this upcoming Holiday season!

Chris L. (San Jose, CA)
Cheaply made, but adequate

I'm not sorry I bought these, but I am disappointed in the quality. The plastic is incredibly thin and it's so easy to cross thread bulbs that it takes twice as long to screw each of the 600 of them in. I don't understand why year after year, products have to suck more and more... this C9 Spool 500' 9" Spacing SPT-1, White Wire is similar to products I've been buying for 15 years and I really wonder how long it will last. I can easily bend, crease, and crush each outlet in my thumb / finger.

Best Spool on the Market!

This spool is just what I needed. The 9 inch spacing is perfect for roof lines. The large spool allows me to have multiple lighting configurations to change to each year.
