Do you ever need heat in your location? Is the electric just for A/C? Sales tax here is 7.25%...no tax on basic grocery store foods...
Just buy a $1 plastic covered LED bulb and install it above the sink and see if it lasts... probably will... the outlet may not last long, though... if getting wet a lot... move the outlet as high as possible...
Yes, the past few years it has been getting below freezing during winter. My friend is very sensitive to the cold. if it's 60 or below he is shivering (he has almost no body fat). He's been having a problem that his girlfriend's niece is sleeping in the living room (they lost their home during the recent hurricane) and she keeps the AC on full blast even when it is cold. Then there's the heating. The niece, nephew, and gf are constantly leaving the front door open. The electric powers the lights, ACs, water heater, tvs, charges devices, computers, etc at my friend's house. At my house it powers the water heater, water pumps, AC, lights, tvs, computers, devices, etc. It has to provide power to the house, shed for water well, and the workshop. My brother constantly leaves lights on so switching to LEDs has helped. We also have a broken back door that is letting cold air in.
Man, I wish groceries were tax free here. No state tax but the city charges 6% tax on all groceries and medicines (including prescription). Nothing is tax free here- not even internet (even though it is federally illegal to tax internet, they get away with it by calling it a "fee").
I found a good light for over the sink. 24" slim utilitech. My friend has several of them in his kitchen. I checked the wiring and I have a little blue plastic box in the cabinet above with a wire. So I can convert it to hardwire or add a plug and use a wireless waterproof switch lower down.
