LEDs use only a quarter the energy of incandescent bulbs.

LED灯使用的电量仅为白炽灯的1/4。

You probably know the company best for its most famous invention, the incandescent light bulb.

你可能最解这家公司最著名的发明——白炽灯。

Thomas Edison lit it up with a million of his new incandescent bulbs.

托马斯·爱迪生用100万个白炽灯泡点亮。

Incandescent bulbs are more brilliant and energy-saving.

白炽灯泡较亮也较省电。

It's the VCR of light bulbs and it's quickly becoming obsolete and for good reason.

像白炽灯这种灯泡界的老爷车很快便会被合理淘汰。

Be careful! An incandescent lamp gets very hot!

小心！白炽灯变得很热！

And unlike a light bulb, a neon sign has no incandescent filaments to burn out, and can shine continuously for 40 years before the gas depletes.

不像电灯泡，霓虹灯广告牌不需要燃烧白炽灯丝，并且能在气体耗尽前持续工作 40 年。

Similarly, you may have noticed that when you sit in front of an incandescent lamp for too long, it feels warmer than the rest of the darkroom.

同样，你可能已经注意到，当你长时间坐在白炽灯前时，会暗房的其他地方更暖和。

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、冰或金属撞击地球的大气层，加热到白炽的样子。

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.

能源部的指导意见说，节能灯泡通常传统白炽灯节省25%-80%的能源，使用寿命是白炽灯的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·爱迪生还没有发明给地球上很多黑暗的地方带来光明的白炽灯。

Incandescent light bulbs and fluorescent tubes are not really suitable for modulation, but they are yesterday's lighting technology.

白炽灯和日光灯的光其实并不适合调制，不过们已是旧式的照明技术。

They are also recyclable, unlike the older incandescent bulbs.

们也是可回收的，不像老式的白炽灯泡。

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，4美元一只的同型号的荧光灯寿命却长达一万小时，相当于13只普通白炽灯的寿命。

But artificial light, whether of the incandescent, fluorescent or LED variety, contains a different mixture of frequencies from that put out by the sun.

而对于各种人造光源，无论是白炽灯，日光灯还是LED灯，们发出的光的混合多种频率，且与太阳光的不同。

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，荧光灯已经有极大的改进，大众技工对新型荧光灯作盲测，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。

Much of the light these cells used would, of necessity, come from incandescent bulbs, fluorescent tubes and light-emitting diodes (LEDs) rather than through the window from the sun.

们所利用的光能中的大部分势必来自白炽灯，日光灯和发光二极管，而并非透过窗户照射进来的太阳光。

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

“但第二点是，那个工作得很好的白炽灯泡贵很多倍。

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

但与白炽灯不同的是，这些灯泡可以很容易地丢弃甚至回收。

Yaay. We're focused on your friendly household light bulb, the incandescent kind.

耶~ 我们先来看你熟悉的家用灯泡――白炽灯。
