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 ...

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 ...

Photonic crystals are nanoscopic structures designed to channel light of specific wavelengths while blocking other wavelengths. This ability to control and filter light with great efficiency makes ...

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 ...

Over on YouTube [Drake] from the [styropyro] channel investigates what happens when you take an enormous tungsten incandescent light bulb and pump 30,000 watts through it. The answer: it burns bright ...

ALBUQUERQUE, N.M. — 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 ...

The once ubiquitous 60W light bulb is about to plop off the production line for the last time across Europe. But while its light may be dimming, it is still illuminating many of our homes. It is at ...

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 ...
