Well, that was my first thought...LED CFL bulbs before that...I like my incandescent bulbs though....warms up the house...like an Easy Bake oven!
Some parts of the country don’t like that extra heat, or paying to get rid of it.
We went all-LED three years ago, with foam insulation. Our electric bill is half of what it used to be.
In Mrs. Alaska's kitchen {we remodeled it to her specs, 300 sq. ft.} we have 14, 65 watt indoor flood lights, on three separate controls.
In the winter or any cool day/night, just fire up all of them, and then put on your shorts.
She usually only has 4-5 of them on at any given time, but it is toasty.
