It started with the Energy Independence and Security Act of 2007

The timeline was supposed to phase out incandescents by Trump's term but he kicked the can. Biden picked it back up and basically did away with incandescents below a certain lumens per kw/H threshold. 

it's a classic case of government interference in the marketplace causing unintended consequences we now all have to live with. If you want a good video on the light waves given off by the different sources of light this is a really good one.
