LEDs use only a quarter the energy of incandescent bulbs.

LED使用的量仅为白炽的1/4。

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

你可能最了解这家公司最著名的发明——白炽。

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

Incandescent bulbs are more brilliant and energy-saving.

白炽泡比较亮也比较省。

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

白炽这种泡界的老爷车很快便会被合理淘汰。

Be careful! An incandescent lamp gets very hot!

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.

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，节能泡通常比传统白炽节省25%-80%的能源，使用寿命是白炽的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.

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

白炽和日光的光其实并不适合调制，不过它们已是旧式的照明技术了。

They are also recyclable, unlike the older incandescent bulbs.

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美元一只的同型号的荧光寿命却长达一万小时，相当于13只普通白炽的寿命。

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，日光还是LED，它们发出的光的混合了多种频率，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，荧光已经有了极大的改进，大众技工对新型荧光作了盲测，比起白炽，受试者更喜欢荧光，而且两种的接口是通用的。

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.

它们所利用的光能中的大部分势必来自白炽，日光和发光二极管，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，它比那个工作得很好的白炽泡贵很多倍。

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