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 ...

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 ...

Over on YouTube [Drake] from the [styropyro] channel investigates what happens when you take an enormous tungsten ...

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 ...

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 ...

Once ubiquitous, the incandescent light bulb has become something of a lucerna non grata lately. Banned from home lighting, long gone from flashlights, and laughed out of existence by automotive ...

ALBUQUERQUE, N.M. -- You can't get something for nothing, physicists say, but sometimes a radical innovation can come close. Researchers at Sandia National Laboratories -- exceeding the predictions of ...
