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 ...

While we've seen graphene LED bulbs before, this is the first time ever graphene has been used to create a filament for an on-chip visible light source. As detailed in the journal Nature ...

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 ...
