Reddit turned me onto this article today. That interested me. I googled and found this page.
I immediately loaded the family in the car and took off for Home Depot to buy some compact fluorescent bulbs (CFLs). They were cheaper than I expected so I bought enough for the entire house.
So far, very nice. We’ll see what it does to my electric bill.
Next step: Turn thermostat on my electric water heater down to low/120^.
