C9 Christmas Lights
A collection page of The Christmas Light Emporium
About
C9 LED Christmas lights use an intermediate E17 screw base — the standard bulb size for rooflines, architectural outlines, and large-scale outdoor displays. The Christmas Light Emporium carries C9 ProCore® replacement bulbs in faceted and smooth lens finishes, including RGB color-changing and ColorCraft® multi-color blends, C9 ProCore® string sets (25 lights, 25'), and C9 LED filament vintage bulbs. C9 is the go-to for gutters, rooflines, fascia, and any run where maximum bulb visibility at a distance is the goal. Backed by our Reindeer Proof™ Warranty. Not sure whether C7 or C9 is the right fit? Our C7 vs C9 guide breaks down the difference. Looking for complete strings?
