C7 LED Christmas Light Bulbs

C7 LED Christmas light bulbs are the classic choice for window outlines, doorway outlines, and wrapping around Christmas trees. The Christmas Light Emporium carries ProCore® C7 bulbs in faceted and smooth lens styles across a full color range, with twinkle variants available. All use an E12 candelabra base and fit any standard C7 stringer.

Bulb vs. Set — Which Do I Need?

If you already have a compatible C7 stringer, buy the bulbs. If you need a stringer and bulbs together, see C7 LED Light Sets — bundled and ready to hang.

C7 vs. C9 — Which Should I Use?

C7 (E12 base) is the standard for window outlines, doorway outlines, and wrapping around Christmas trees. C9 (E17 base) is larger and the standard for rooflines, architectural outlines, and large commercial displays.

How to Choose

C7 bulbs are best suited for windows, doorways, porch railings, and wrapping trees where a mid-size bulb creates a warm, classic look at close range. Choose your lens style — faceted for added sparkle or smooth for a traditional glow — and select a color that complements your overall display. Confirm the base type (E12) matches your existing C7 string sockets before purchasing.
