More than a century after their invention, tungsten filaments—the coiled metal wires at the heart of many incandescent light bulbs—continue to be popular. This is despite the growing market for LED ...

As inventors in the early 1900s vied to devise the best incandescent lightbulb, tungsten won out over carbon for making filaments. Today, however, there’s a form of carbon that was unknown back ...

Although tungsten-filament bulbs are the world’s most extensively used light source, they are inefficient and generate more heat than light. However, a new microscopic tungsten lattice created at the ...

This month, let’s take a deeper look at one of the most ubiquitous forms of illumination in our world: tungsten or incandescent bulbs. Incandescent means light from heat, which also includes the light ...

Tungsten-filament bulbs — the most widely used light source in the world — burn hands if unscrewed while lit. The bulbs are infamous for generating more heat than light. Now a microscopic tungsten ...

You probably know that an incandescent light bulb uses a tungsten filament. What's even cooler is that it's got 20 inches of double-coiled filament -- and tungsten is a brittle mineral that, under ...

With most of the apparatus and instruments we now take for granted yet to be developed, the early pioneers of the Electric Age had to bring a lot to the lab besides electrical skills. Machining, ...

Light bulbs are living on borrowed time, but why do their timers tend to expire just as you turn on a light, instead of flickering out randomly? Everyone has had the experience of coming home from a ...

Researchers create a prototype bulb with a carbon nanotube in place of the standard tungsten filament. It uses less power, burns brighter and could lead to the first major overhaul in bulb design in a ...

Researchers at Sandia National Laboratories -- exceeding the predictions of a 100-year-old law of physics -- have shown that filaments fabricated of tungsten lattices emit remarkably more energy than ...

Imagine a light bulb that has been burning since 1901. Nestled in a quiet Californian fire station, the Centennial Light challenges today's disposable culture, offering a glimpse into a past where ...
