Lights are great as expected!

I couldn’t be happier with my order! Everything arrived in a timely fashion and was packaged securely. As I build my display at my new house over the next couple of years Christmas Light Source will be my go to store for all supplies!

Great source for lighting and best price

No need to run all over town Christmas Light Source has everything you need at the best price. Careful shipping and arrived in days!
We found so much we could not find available at any other stores. Will order anytime I need new strands and replacement bulbs from this company.

Nice bright lights for my pallet Christmas trees.

Exactly what we needed

Bought these to go with a 50 ft string. Bulbs worked great. Only had one go out in the first use. Packaged very well and have been working for the past two weeks with no issues.

Work Well

I only had 1 bulb blow out at 1st start. I will review all items with this one. The only thing I thought I ordered a 100' that had a plug in between. That was no problem and I can always add a break in between if I get tired of a hundred footer. By the way these are not for Christmas. They are for FREEZE protection on my Orange; Lemon and Tangelo trees. See now you have another selling point.
