You may be surprised to learn the 95% of the energy produced by a standard light bulb is heat. This means that only 5% of the energy expended when using this common item meets the primary purpose of providing light. This makes traditional light bulbs highly inefficient and very wasteful. The world is changing, however, and the demand for energy efficient products is becoming greater by the day. Traditional light bulbs and their energy wasting will soon be entirely replaced by better, more efficient lighting choices.
