LED Bulbs

LED bulbs are now the way to go for energy-efficient lighting. If you have any incandescent bulbs, go ahead and replace them now. If you have compact fluorescent bulbs, wait till they burn out to replace them. LED bulbs are super cheap (less than a dollar) at Habitat ReStore and close to that at certain other stores, including Ace Hardware, Home Depot, Walmart, Lowes and Goodwill.
