The question to ask is: Why not switch to CFLs?

所以，问题应该这么问：为什么不换成荧光灯呢？

So you can see the point. CFLs are simply a smarter way to light your home.

所以，你应该明白了，荧光灯绝对是家用照明的明智选择。

Meanwhile, CFLs and LEDs really took off.

同时，CFL 和 LED 真正起飞。

Unlike the old CFLs, the new CFLs use a mixture of different phosphor coatings.

与旧的 CFL 不同，新的 CFL 使用不同荧光粉涂层的混合物。

First of all, it' s true that CFLs cost more than incandescent bulbs.

首先，节能灯确实比白炽灯泡更贵。

The light from new CFLs is almost impossible to tell apart from incandescent light.

来自新节能灯的光几乎无法与白炽灯区分开来。

Second, it's true that CFLs can release small amounts of mercury.

其次，节能灯确实会释放少量汞。

Incandescent bulbs are less efficient than CFLs, which means they use more electricity.

白炽灯泡的效率低于节能灯，这意味着它们消耗更多的电力。

But this problem has been solved in newer CFLs.

但这个问题在新型 CFL 中已经得到解决。

Third, it' s true that old CFLs produce light that was not very pleasing to the eye.

第三，旧式节能灯确实发出的光不太悦目。

According to one estimate, a consumer investing $100 to switch from incandescent bulbs to CFLs can save $500 over the lifetime of the CFLs.

据一项估计，消费者投资 100 美元从白炽灯泡改用 CFL 可以在 CFL 的使用寿命内节省 500 美元。

We have, I think, 500,000 people who are signed up and have started recycling or using CFLs or that are doing something related to wellness.

我认为，我们有 500, 000 人注册并开始回收或使用 CFL， 或者正在做与健康相关的事情。

CFLs have come a long way lately. Popular Mechanics did a blinded study with new CFLs and participants preferred the CFL light compared to incandescent bulbs and they fit in the same fixtures.

近来，荧光灯已经有了极大的改进，大众技工对新型荧光灯作了盲测，比起白炽灯，受试者更喜欢荧光灯，而且两种灯的接口是通用的。

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。

The next time you're at the store, pick up a four-pack of CFLs and replace the bulbs that are on the most, maybe the porch light, then ask your friends: Why haven't you switched?

你下次购物的时候，买一盒四只装的荧光灯，换掉家中常亮的灯，比如门廊灯。然后反问你的朋友：为什么不换成荧光灯呢？
