[RFI] "No RFI" LED bulbs

Yes, the issue is when the bulb it lit either by opening the door or
operating the light manually.  When some fluorescent or LED bulbs are lit
they produce RFI that interferes with the door opener receiver and either
captures the receiver input or desenses it requiring the transmitter to be
moved very close to the receiver to overcome the bulb's interfering signal.
