Hello,
It seems that this issue may be caused by your candelabra’s sockets.
We suggest that you switch/rotate the bulbs between the 6 sockets in order to check whether this is an issue related to the LED bullbs or strictly related to your sockets.
Also, are you using any connectors to do so ?
You may also reach out to one of our Customer Service Representatives at 1-877-333-0098
We hope this will help,
