Lighting uses seven to 10 percent of the total energy consumed in a home. There are a number of ways that you can reduce your electric energy consumption from lighting.
Turn off lights when you don’t need them.
Use photoelectric lighting controls such as motion or occupancy sensors or timers to turn outdoor lighting on and off automatically.
Use the more efficient PAR bulbs, especially for task and accent lighting. For example, a 50-watt PAR30 bulb produces more than three times more light than a 65-watt BR30 bulb.
Use energy-saving LED or fluorescent bulbs wherever possible. They produce significantly more light for every watt consumed compared to incandescent sources. Also, these new types of LED and fluorescent bulbs have excellent color qualities that equal that of incandescent sources.
Look for products that carry the ENERGY STAR® symbol.
Today’s energy-efficient light bulbs, such as compact fluorescent or LED, produce significantly higher amounts of light for every watt of energy used. It is most important to remember, however, that wattage does not measure light output; it only measures the electrical consumption of the bulb.
