We have just switched over to LED lights in the house. The bulbs are a little pricey compared to regular bulbs but they pull a fraction of the power and are supposed to last for years. Here's hoping. There are a few places in the house, like the basement, where we seldom venture so the bulbs have not been switched out there. Maybe later. Hopefully we'll see a difference in the hydro bill next month. In the meantime, the new bulbs shed way more light than the old ones. We shipped the 60 and 100 watt incandescent bulbs off to the Restore here in town. They sell salvaged household building supplies and appliances and the proceeds go to Habitat for Humanity.
This whole procedure has left me in awe of just how many sources of light we have in this tiny little house. We would need another eight bulbs and one LED fixture to move totally to LED lighting. Perhaps in time. I'll need to save up again for a bit.
