As seldom as the lights in the garage door opener operate, buy
simple incandescent bulbs designed for 130 VAC and they will
probably outlast you! And they don't cause RFI!
The builder of our house installed 130V bulbs and some lasted
over 15 years! The lamps in our chandeliers have NEVER been
replaced in 20 years. True, they don't get used that often and I
have installed dimmers for control, but still!

Subject: [RFI] Garage Door RFI
For years I've easily opened my garage door with the car's remote system
from 400 ft. away. A few weeks ago I noticed that was no longer
possible. Even from my own driveway it was often hard to open it. I
had installed a couple of 11w LED bulbs in the main motor unit. I had
no concern, since I have 35 Cree LED floods in my house that do not
create noise beyond a few inches. This was different. Those bulbs
generated noise in the 300Mhz spectrum that interfered with the
reception from the remote. Replacing them with 23w CFL lights solved
the problem. Beware of LED lights in a garage door opener!!!
