C9 LED Bulbs

LED Christmas lights

This entire line of C9 bulbs have E17 threaded bases which makes them compatible with traditional C9 cords so if your Christmas stash includes string wire that’s in good repair, you can purchase these retrofit bulbs to migrate your display from incandescent to energy-efficient LED.

These bulbs have an E17 base. If you are unsure what size base bulbs you need, these are larger than a night light base which is E12. So if you are trying to match or replace bulbs, check to see if your sockets are larger than a nightlight. If your current bulb fits a nightlight then check out our C7 (E12) line of LED bulbs.

Head over to our Get This Look page which features several projects using C9 LED bulbs for inspiration and tips.

Our styles of C9 LED bulbs:

  • Smooth
  • Faceted
  • Opaque
  • Flashing/Twinkling

Note about LED Christmas bulbs and animation:

Our bulbs are specified as Dimmable and Non-dimmable.

This means that you cannot use them with animation unless they are noted as dimmable. quickly turning them on and off repeatedly will damage them. Only our dimmable bulbs can be ramped with a variable resistor or dimmer switch.

In other words, if you are planning to connect to an animation hardware and software package be sure to choose dimmable LED bulbs or stick with traditional incandescent lighting.
