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 ...

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 ...

An energy-saving light bulb containing LEDs uses up to 80% less energy and lasts up to 25 times as long as a traditional incandescent bulb. There’s just one problem: many people think that the quality ...

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 ...

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 ...

PHOENIX -- Saying they were striking a blow for individual rights, a Senate panel voted Tuesday to keep old-fashioned tungsten-filament light bulbs legal in Arizona long after they're banned by ...
