While that's the same basic concept that you see in an incandescent bulb, the graphene filament measures just one atom thick -- this is the world's thinnest light bulb, and may be close to being ...

and the fancy fake filaments are meant to be looked at. Any brighter and you'd develop a constant squint. This bulb is extra warm in tone. See how the spectrometer chart kind of leans to the right ...

Note that these are bulbs that have a low/high filament; i.e., one filament is “on” all the time as the running light, and the other filament comes on as the brake light. If your motorcycle takes a 21 ...

each of which controls two bulbs on the display. An example of a Wamco minitron bar graph display. Each window contains an incandescent filament. [Source: industrialalchemy.org] [Industrial ...

A flexible contact on the base of the bulb allows the second filament to be turned on by screwing it in a little tighter. Kunkle can't say for certain how long the bulb has been operating in the ...

In Livermore, California, a remarkable light bulb has defied the odds for over a century. Known as the Centennial Light, this carbon-filament bulb has been glowing since 1901, earning it the title ...

The Guinness Book of World Records, Ripley's Believe It Or Not, and General Electric agree the four-watt, carbon filament bulb is the longest-living in history, despite two moves and a few power ...

Over 130 years ago, Thomas Edison used carbon as the conducting filament in the very first commercial light bulb. Now a team of scientists and engineers have used that very same element ...

Researchers have developed a light-emitting graphene transistor that works in the same way as the filament in a light bulb. "We've created what is essentially the world's thinnest light bulb ...
