Dont like coming home to a dark house? Instead of leaving lights on, put timers on a few of the lights in your home, or install motion detectors on exterior flood lights to improve your home security. After you get inside, the sensor will remember to turn the lights off. |
ENLIGHTENING WARNING!
Halogen torchiere lamps have grown in popularity. Although relatively inexpensive to purchase, they are expensive to operate and very inefficient. The halogen bulbs in these lamps operate at temperatures much hotter than regular bulbs and can CAUSE FIRES, warns the U.S. Consumer Product Safety Commission (CPSC). Consider a safe Energy Star torchiere. |
