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 ...

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 ...

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 ...

Philips Hue on Wednesday introduced over a dozen new lighting products -- and announced a partnership with streaming music service Spotify to sync your Philips Hue lights with the beat, as well as the ...

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 ...

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 ...

Quartz Tungsten Halogen (QTH) lamps are proven visible and near infrared sources, thanks to their smooth spectral curve and stable output. They generate little ultraviolet radiation and do not exhibit ...

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 ...

The warm glow of an old electric light-bulb, which has been banned in many countries because it is so energy inefficient, may soon be making a comeback following a breakthrough in “light recycling”.
