And so one of them is called tungsten light.

因此其中之一被称为钨灯。

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

由于这些不是钨丝灯，因此看起来真的很蓝。

But, pumping heat out of your house isn’t cheap and turning on one air conditioner is the same as running dozens of tungsten light bulbs.

但是把热气从房子里赶出去可不便宜，而开一台空调够开几十盏电灯泡了。

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.

而且超级不省电的钨丝电灯泡，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。
