LEDs use only a quarter the energy of incandescent bulbs.

LED灯使用电量仅为白炽灯1/4。

Now compare that to a single CFL that costs about $4. A CFL of the exact same lamp will last 10,000 hours that's about the same as 13 regular light bulbs.

与之对比，4美元一只同型号荧光灯寿命却长达一万小时，相当于13只普通白炽灯寿命。

What you're actually seeing is a tiny bit of interplanetary debris: rock, ice, or metal ramming through the Earth's atmosphere, heated to incandescence.

岩石、冰或金属撞击大气层，加热到白炽样子。

The department's guidance says energy-efficient light bulbs typically used 25%-80% less energy than traditional incandescents and last three to 25 times longer.

能源部指导意见说，节能灯泡通常比传统白炽灯节省25%-80%能源，使用寿命是白炽灯3 - 25倍。

A century ago Thomas Edison had not yet invented the incandescent lamp to bring light to many dark places of the earth.

一个世纪以前，托马斯·爱迪生有发明给上很多黑方带来光明白炽灯。

They are also recyclable, unlike the older incandescent bulbs.

它们也是可回收，不像老式白炽灯泡。

But number two, it's many times more expensive than that old incandescent bulb that worked very well.

“但第二点是，它比那个工作得很好白炽灯泡贵很多倍。

But these bulbs can easily be disposed of and even recycled, unlike incandescents.

但与白炽灯不同是，这些灯泡可以很容易丢弃甚至回收。

The structure gives off " a warm, radiant incandescence" from within.

该结构从内部散发出“温暖、光芒四射白炽光” 。

It's a 60-watt incandescent bulb, so it uses 60 watts an hour.

这是一颗60瓦白炽灯泡，所以它每小时耗电60瓦。

They look and behave exactly like the old incandescents.

它们外观和行为与旧白炽灯完全一样。

Inventing a viable electric light was hard, I mean, this is the typical incandescent design, which just involves passing electric current through a material making it so hot that it glows, less than 5% of the electrical energy comes out as light.

发明一种可行电灯是很困难, 我意思是, 这是典型白炽灯设计, 只需让电流通过某种材料，使其变得非常热，从而发光，只有不到5%电能以光形式出现。

You need red lights like of like a Christmas tree red lights or any lights that where they're not very blue, not LEDs, you know, incandescent bulbs or red lights, you'll sleep better and your babies will sleep better.

你需要像圣诞树那样红灯， 或者任何不太蓝灯光，不是LED， 你知道，白炽灯泡或红灯，这样你会睡得更好， 你宝宝也会睡得更好。

It was here that he and his research team developed the first successful incandescent light bulb and a working phonograph, the first device ever to record and play back the sound of a human voice.

正是在这里，他和他研究团队开发了第一个成功白炽灯灯泡和一个有效留声机，这是有史以来第一个记录和播放人声设备。

It's like between the return of the incandescent light bulb and the return of water pressure, these are things that actually genuinely improve the life of your average citizen, right?

这就像在白炽灯泡回归和水压恢复之间，这些实际上是真正能改善普通市民生活事情，对吧？

And in India, they're looking to replace a quarter of a billion incandescent light bulbs with LEDs, which will save them seven billion dollars in energy costs.

在印度，他们希望用 LED 替换十亿个白炽灯泡中四分之一，这将为他们节省 70 亿美元能源成本。

As far as we can tell, it was an explosion of white hot light that came from nowhere, and then vanished.

据我们所知， 那是一场来自无处白炽光芒大爆炸，然后就消失了。

From some night at limelight or the tunnel?

就像刚有白炽灯和隧道年代？

Even so, Edison did not become a " hands-off boss." In the 14 months of researching the incandescent bulb, Edison spent an average of 17 hours a day in the laboratory.

即便如此，爱迪生并有成为一个“不干涉老板” 。 在研究白炽灯泡 14 个月里，Edison 平均每天在实验室里呆 17 小时。

Edison owned the patents for the incandescent light bulb that was initially designed to run on DC power.

爱迪生拥有最初设计为使用直流电白炽灯泡专利。
