Science DiscussionsIncandescent bulbs, which generate light by heating up a tungsten filament until it glows almost white hot have long been recognized as being highly inefficient, losing a major proportion of their energy to heat. In comparison, fluorescent lamps, which generate light through using electricity to excite gas, generate relatively little heat and are about four times as efficient as incandescent bulbs. Naturally manufacturers of incandescent bulbs are resisting the planned legislation. However, there is little doubt that in an energy conscious state like California within an increasingly energy conscious world, the days of the nearly century and a half incandescent lighting technology are numbered.{moscomment} |
