So there is a actual difference not just some bullshit switching tech that means more expensive run less to cheat the tests. Anyway we went with an E rated one because A was twice the price.
It would've paid for itself over its life, but it's not for us and ain't nobody got time for that.
Yeah, that's progress. But there's a measureable difference in power consumption. So, I want to know why that is and why it costs more.
