These bulbs replace regular incandescent bulbs that range from 45-100 watts. In comparison, they use only 3-13 watts of power and will last up to ten years. This figure is based on using the bulbs an average of eight hours a day over the course of the ten year period. It is said the average incandescent bulb will cost you up to $20.00 a year to light your home, while these new bulbs can do the same for as little as $2.00
