A) LED
NJ2X Notes:
LEDs (Light Emitting Diode) are replacing incandescent and other less efficient forms of lighting. This replacement has been evident for years now in low wattage lighting applications such as indicator lights and back lighting on radios. Higher wattage lighting is now also being replaced by LEDs. We use Philips LED light bulbs throughout our home and really love the how they have reduced our power bill while producing an excellent quality of light that lasts.
