C7 Green Faceted ProCore® LED Christmas Light Bulbs

C7 SMD LED Bulbs

These products are intended to replace C7 incandescent bulbs in an AC powered string. They work great! Colors (red, green, cool white) are vivid & bright. Of note, you must tightened these very tightly into older C7 strings, likely due to dirt/corrosion buildup in older strings' contacts. Or, you could try to clean the center conductor inside each socket. These are robust globes, so they'll take the tightening.
