The spectra of a selection of energy efficient lights. The lights are photographed through a diffraction grating to show the spectra. The lights on the left are energy efficient LED bulbs of different designs,the fourth bulb is a coiled fluorescent tube,and the bulb on the far right is a standard incandescent lamp using a tungsten filament. Each colour band corresponds to a specific energy of photon released by electrons jumping to different energy levels | |
