As the electrons try to crowd through a hair-thin tungsten wire, the energy spent overcoming resistance turns into heat.

当电子试图挤过一根细细的时，克服电阻所消耗的能转化为热。

Since these are not tungsten lights, this looks really blue.

于这些不灯，因此看起来真的很蓝。

Also the horrifically energy in-efficient tungsten light bulbs that have remained unchanged for a century are giving way to CFLs and LEDs – greatly reducing the amount of energy required to light a room.

而且超级不省电的电灯泡，在原地踏步一个世纪之后，终于让位给了荧光灯和 LED，现在照亮整个房间可省电多了。
