Frequently Asked Questions

What bulbs are compatible with this spool?

This spool is compatible with any C9 (E17) base bulb — LED or incandescent, any style or color. It pairs great with our ProCore® LED bulbs.

Do I need to buy plugs separately?

Yes — no plugs are included with the spool. You\'ll need to add slide-on vampire plugs to your cut wire ends to connect to power. These plugs press onto SPT wire without any tools.

What\'s the difference between a spool and a pre-cut stringer?

A spool is a 500\' bulk reel you cut to any length you need — ideal for large-scale installs or custom run lengths. A pre-cut stringer comes ready to use at a fixed length (25\', 50\', or 100\'). Check our full selection of stringers and spools to find the right fit.

Can this spool be used outdoors?

Yes — UL Listed for both indoor and outdoor use. Designed for rooflines, eaves, railings, decks, overhead canopies, outdoor trees, and large commercial and municipal displays.
