If you think this is just a ham problem you may want to think twice.
The silver lining is that since it has the potential to interfere with aircraft we can likely now see manufacturers being a bit more careful with EMC of their lightbulbs.
I have 100% LED here (about 50 bulbs total). I have had only one issue with RFI which was promptly dealt with by the manufacturer (Cree) and they sent me a new two pack of improved bulbs.
