Comparison of efficient and standard light bulbs, thermographic timelapse. Thermography shows the temperature of an object, on a scale from dark blue to pink white (as seen at right). These bulbs have been turned on and left for ten minutes. The incadescent bulb clearly gets a lot hotter than the energy-saving bulb at right. Energy lost as heat is wasted, and this clip reveals that the energy-saving bulb does not waste as much energy as the newer bulb. | |
