After installing these bulbs in my desk lamps, I noticed that I had to be very close to the garage door for it to open. The wireless alarm started draining the batteries like crazy and the WiFi performance was worse than it was. I didn't know that lightbulbs could cause problems because sometimes everything worked fine and sometimes it didn't. I did an experiment today, turned off all those lights and the garage door opener works across the street, turn it on and I had to be 3 feet from the garage door. I've tried it 3 times just to be sure and it absolutely follows the bulbs on or off. The WLAN speed has been increased from 10 Mbit/s to 40 Mbit/s. Time will tell with an alarm clock. These are IKEA table lamps, they are nothing special and are not dimmable. These lightbulbs contain a lot of electronics and generate radio frequency energy. Apparently, this is enough to disrupt many systems. Pay attention and get FCC certified light bulbs. I love LED bulbs but now I know they can cause problems with wireless systems.
