Have a Light-Changing Day

If you are like most people, you change fluorescent bulbs only when one burns out. This is actually the wrong way to do it from an energy-consumption perspective. After a bulb reaches about 80 percent of its rated life, it begins to tax your lighting system, wasting energy. So to reduce your energy bill, save money, and use labor efficiently, you should change all of your bulbs simultaneously, on a schedule. And when you replace them, use T8 tubes and upgrade to electric ballasts, thereby reducing the electric load by 42 percent.
