Easy to use

C7 bulb string was easy to string out and cut to fit with the plug ends. We set up 350 bulbs on our roof and they look great!

First Time Christmas Lights

This is the first time my church decided to use this type of lighting and it couldn't have been easier to do. Very easy to cut the cord to length and put an end on it. This gave great versatility for installing the lights. I am so glad I found your company. I will definitely use you again.

Shipped so quickly

Great customer service and a great, quality product. Thanks very much!

Exactly what I ordered

Ordered the sturdier SPT-2. This spool along with the gilbert plugs makes it so easy to do your own xmas lights without paying every year for the professional install.

Great Product

The light strand was easy to use, and we now have lights decorating 350ft of fence. This is a well made product, and it is well packaged


They are the ideal light up string for Christmas that I needed

Very happy with all products I purchased. Very easy to install and it showed when you said it would. Thank you.

Black is better than green

For our project we were happy to find this cord with black wire. We are decorating for an event and the black is much less noticeable than the green. Worked as expected, would purchase again. I forgot to order plugs and will remember to do that next time.
