From News Coulomb.

I just picked up some more high efficiency LED lightbulbs, so I wanted to take some time to discuss the advantages of switching out bulbs and frame those energy savings in relation to EV energy consumption. The numbers are quite impressive because the average American household could transition to 100% EV without increasing their power bill simply by switching to higher efficiency LED lightbulbs.

*Note: It was Dubai that contracted Phillips for the ultra-high efficiency LED bulbs.
