The size and wattage differentiate the bulbs.

•  G30: 1.2” diameter; 5 Watts per bulb
• G40: 1.6” diameter; 5 Watts per bulb
• G50: 2.0” diameter; 7 Watts per bulb

See below for size comparison:

C7 base and C9 base refer to the socket size on the cords and the screw in part of the light bulbs. The C7 base is the smaller of the two and is 3/8” diameter. The C9 base is slightly larger at 5/8” diameter. As long as the cords and bulbs selected are both the same type (e.g. C7 cord and C7 bulbs) they will work together.

We have a large variety of string light sets. You can also mix and match your own combination of cords and bulbs as well on the light bulbs and light strings pages.

Yes. The string lights are designed for indoor and outdoor use and can be left outside year round. The cords are water resistant and can survive rain and inclement weather. (Please note although they are water resistant the cords are not designed to be submerged and are not intended for underwater use.) 

In the 18 gauge wire, our 10′ 25′ and 50′ cords have end to end connectors; however the 100 foot cords do not. In the commercial 16 gauge wire the 24′, 50′ and 100′ cords have end to end connections.

The total string light length plugged into a single socket is limited by the wattage rating of the wire. Our standard C7 and C9 cords are rated for 959 total watts and 8 amps. Using 7 watt bulbs you are limited to 125 feet on a single plug, while 5 watt bulbs would reach 175 feet on a single plug. If the cords connected together go over the 959 watt limit they risk blowing the fuse. The 0.6 watt LED bulbs allow much longer cord lengths on a single plug at 1,598 feet.

Our commercial 16 gauge wire cords are rated for 1,200 total watts. For examples, if using an 11 watt bulb you can connect up to 220 feet. If using a 1 watt LED bulb you can go up to 2,400 feet!   

On our standard C7 and C9 base cords sockets are spaced every 12″. A 25 foot cord has 25 sockets. A 50 foot cord has 50 sockets. A 100 foot cord has 100 sockets.

On our commercial C9 base cords the sockets are spaced every 15″.

On out commercial E26 base cords the sockets are spaced every 24″

Our standard C7 and C9 base cords are 18 gauge wire. The cords are rated for up to 959 watts.

Our C9 and E26 base commercial cords are 16 gauge wire rated for up to 1200 watts.

Most of our light bulbs come in boxes of 25. We also sell some specialty bulbs in boxes of 12 or as individual light bulbs.

Our standard C7 and C9 base cords come in 25, 50, and 100 foot lengths.

We also sell commercial cords available in 24, 25, 50, 100, and 330 foot lengths.

We include a spare fuse in each cord so that you can change it if one blows. Inside the plug of your cord there is a small compartment that slides open. There are two fuses inside. The loose one is the spare. If a fuse is bad it will be a brownish color instead of being clear. Unplug the cord, switch out and replace the bad fuse, then plug your lights back in.

Yes. For permanent applications or heavy duty cords you can select from our C9 or E26 commercial grade cords.
