ProCore™ LED Christmas Light Bulbs

ProCore® LED Christmas light bulbs are The Christmas Light Emporium's professional-grade C7 and C9 replacement bulb line. The ProCore® lens features indestructible polycarbonate lens construction and precision light filtering that produces stronger, more vibrant output and significantly better color consistency run-to-run. If you've ever noticed color variation between brands or boxes, ProCore® was designed to eliminate that.

Faceted vs. Smooth

Faceted ProCore® bulbs have a multi-faceted surface that catches and scatters light for a sparkly, multi-directional effect. Smooth ProCore® bulbs have a clean, rounded finish for an even, uniform glow. Both deliver the same indestructible polycarbonate lens construction and precision light filtering.

Bulb vs. Set — Which Do I Need?

If you already have a compatible stringer, buy the bulbs. If you need a stringer and bulbs together, see the C7 LED Light Sets or C9 LED Light Sets collections — each includes a stringer and ProCore® bulbs bundled, ready to screw together and hang.

How to Choose

First identify the base type you need: E12 for C7 sockets, E17 for C9 sockets. Then choose a lens style — faceted for sparkle, smooth for a traditional glow, or a specialty finish for unique effects. Confirm the bulb color matches your existing display scheme, and purchase enough bulbs to replace or supplement your current string.
