[Shop-talk] LED light bulbs in garage door operators

LED light bulbs in garage door operators.

The 75-watt conventional rough-service incandescent bulb in my garage-door opener burned out.  Since one wants a vibration-resistant bulb, I replaced it with a 17-watt LED unit that gives the light of a 75-watt incandescent.

The opener started working intermittently.  Sometimes it would open but not close with the remote, sometimes it would close but not open.  Sometimes it worked from inside the garage, sometimes only from outside.  Only consistent thing is that the hardwired doorbell button in the garage always worked.  All the wireless remotes including the keypad on the outside of the garage acted goofy.

Took the bulb out completely.  Everything worked fine.

Put in an ordinary 75-watt that was handy.  Everything worked fine but the bulb burned out fast.

Put in a new rough-service incandescent bulb.  Everything works fine.

Obviously, I don't want to use LED lights in this operator.  Somehow the circuitry in a multi-LED bulb does weird things with the radio in the operator.  Anybody else ever see this effect?
