While your home’s lighting uses less energy than heating, cooling and water-heating, you can still reap considerable energy savings by making a few changes.
• Place compact fluorescent bulbs in light fixtures that are most frequently used (those operated more than three hours per day). They draw about one-quarter the energy and can last 10 times as long. And many of the newer bulbs fit into standard screw-in socket fixtures.
• Keep lights off in unoccupied rooms and get in the habit of turning off the light every time you leave a room for more than a few minutes.
• Use low-wattage bulbs when you can. Bright lights are often not needed in hallways or closets.
• Clean light bulbs and fixtures since dirt can reduce light output by as much as 10 percent.
• Remove unnecessary bulbs in track and recessed lighting. Positioned correctly, three bulbs can sometimes provide nearly the same light as four.
• Install dimmers in areas where they make sense, like the dining room and bedroom. The amount you dim equals your energy saved. For example, lights dimmed 15 percent reduces energy consumption up to 15 percent.
• When working at a desk or workbench, use task lighting. Other lights in the room could be turned off or dimmed.
• Pull the plug on instant-on appliances (such as televisions) when you don’t plan to use them for a few days or more. They draw current even when they’re switched off.
