Apparently, incandescent lightbulbs haven't been completely banned and there is an industrial source for them which projects a 7-year bulb life when burned an average of four hours a day. And...they're made in the U.S.A. Now, I absolutely detest fluorescent lighting, so this website is a real find. Think I'll order a supply and see if they really last for seven years. Maybe I'll date the bulbs before I screw them in. And a reminder: don't hide any of your lights under a bushel basket!
