Frequently Asked Questions

What bulbs are compatible with this stringer?

This stringer is compatible with any C7 (E12) base bulb — LED or incandescent, any style or color. It's a great match for our ProCore® LED bulbs.

Can I connect multiple stringers end-to-end?

This stringer has a male plug only (no female end). It cannot be connected end-to-end directly. For longer runs, plan your layout with multiple circuits or use a socket spool to cut a custom single-run length.

What's the difference between a stringer and a socket spool?

A stringer is pre-cut to a fixed length and ready to use out of the box — ideal for most residential and commercial installs. A socket spool is a 500' bulk reel you cut to any custom length, which is better for large-scale or oddly-sized runs. Check out our full selection of stringers and spools to find the right fit.

Can this stringer be used outdoors?

Yes — UL Listed for both indoor and outdoor use. Designed to handle rooflines, eaves, railings, decks, overhead canopies, and outdoor tree lighting.

Questions & Answers

What is a C7/C9 Christmas light stringer?

A C7/C9 stringer is the empty cord with evenly spaced sockets into which you screw ProCore C7 or C9 replacement bulbs. The stringer provides power and socket spacing; the bulbs provide the light and color. You choose the stringer spacing and length, then select the bulbs separately.

What socket spacings are available for C7/C9 stringers?

We carry stringers in various socket spacings. A common spacing is 12 inches between sockets. Check the stringer product page for available socket spacing options.

Can I use C7 and C9 bulbs on the same stringer?

No — C7 and C9 bulbs have different base sizes and require stringer sockets designed for their specific size. Use a C7 stringer for C7 bulbs and a C9 stringer for C9 bulbs.

How many C7/C9 stringers can I connect end-to-end?

Connection limits depend on the specific stringer and the bulbs you are using. Check the stringer and bulb product pages for load ratings and recommended maximum run lengths.

Are C7/C9 stringers rated for outdoor use?

Yes — our C7/C9 stringers are rated for outdoor use. For exposed outdoor connections, use moisture seals or waterproof wraps to protect against rain and humidity.

Do I need sockets and seals for an outdoor C7/C9 installation?

Weatherproof seals that protect the bulb-to-socket connection are strongly recommended for outdoor installations, especially in wet climates. See our C7/C9 Sockets and Seals collection for compatible options.

What warranty covers C7/C9 stringers?

Our C7/C9 stringers carry standard product coverage. The ProCore LED bulbs you use in the stringers are covered by the Reindeer Proof Warranty. Check product pages for full details.

How do I calculate the number of bulbs I need for a stringer display?

Measure your display run in feet and divide by the socket spacing in feet to get the number of sockets needed, which equals the number of bulbs. Our customer service team can help you calculate quantities.

Are stringer replacement sockets available if one breaks?

Yes — individual sockets and seals are available. See the C7/C9 Sockets and Seals collection if you need to replace damaged sockets on an existing stringer.

What ProCore bulb colors can I mix on one stringer?

You can mix any combination of ProCore C7 or C9 bulb colors on a single stringer, letting you create custom color patterns — alternating colors, gradient effects, or any sequence you choose.
