We did start to light up more stuff immedeately, and as soon as the technology was (cheaply) available :

Quite a lot of light produced by LED is not for interior lighting.. It's for lighting screens.. TV , any number of mobile gadget, billboards... It's all done by LED nowadays, and quite bright as well.

I think if you take all those lumens into your equations you'd get quite a different figure.
