Caller: LED lighting replacements

Calling about replacing household lights with LED lights. After telling her I already have them, she then asks how long ago? Why would that matter I ask. This is for gen 3 lights she says. What’s the difference I ask. Well gen 1 is incandescent, 2 is compact fluorescent “twisted bulbs” she called them, and 3 is LED. I tell her I definitely have LED lights and she then says “f... off” and hangs up!
No government payment to them so they get angry it seems...
