LED bulbs are essentially high-tech versions of LED technology that you've seen in early calculators and watches. Essentially, they are electronic devices with mini transformers, chip-sets and light-emitting diodes (LED) that converts electricity into light. They do this extremely well and efficiently, converting most of the energy consumed into light and very little into heat. On the other hand, standard incandescent bulbs convert most of the energy consumed into heat and very little into light. That is why a 8 Watt LED bulb produces as much light as a 65 Watt incandescent bulb.
