Old stock. Bypassing the ban would be buying the bootleg incandescent lamps GE made (or still makes) after the incandescent bans on 40-100w A19 lamps in 2012-2014. I find older incandescent lamps at thrift and ReStores all the time.
It good that old stock can still sometimes be sold. But, last time I wasn’t allowed to buy from the same old stock for some reason.
