We did the same thing - have two big plastic bins full of them :-)
(And you can still buy them, if you look around. I don’t know why, never understood exactly how the ‘ban’ works; but they’re out there...)
As I understand it, it was the manufacture of these bulbs that was banned after a certain date. There’s no ban on buying or selling them as long as there are any available.
Though I have no doubt that the liberals would have dearly loved to ban the use of the bulbs. I suspect they would have done what was done in Argentina if they could. That being sending the Army into people’s homes to take their incandescent bulbs away.
#45. Back when the “stupid” ban on old style bulbs was put in, there was a clause that allowed certain types of bulbs made in a state to be sold only instate. This included them. Don’t know if this is still in effect or not. I hate the curly bulbs that contain Mercury. Hard to find a place to recycle them.
