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 ...

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 ...

Of course, it would not deliver 3-way functionality, as it is made with just a single filament. That being the case, using a standard bulb in a 3-way socket is not generally recommended ...

I alluded to the latter attribute within that earlier three-way bulb dissection project: (By the way, notice the hint of what looks like a filament structure inside this dimmable LED bulb. You’re ...

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 ...

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 ...

“And we started hearing that some consumers had concerns about the more distinctive yellow filaments in LED bulbs especially when the lights were off in a fixture without any shades. They loved ...

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 ...

Manufacturers and the government have sought new types of fixtures that would use less energy than Edison's pear-shaped glass bulb with a heated tungsten filament glowing inside. Why are ...

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 ...

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 ...
