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 ...

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 ...

Many credit the invention of the incandescent light bulb with Edison or Swan but its development actually took place over two centuries and by the time Edison and Swan got involved, the tech was down ...

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 ...

Do you know that the light bulb, a revolutionary invention that transformed daily life, fundamentally works by converting electricity into light through heat? This ingenious device, commonly found in ...

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 ...

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, ...

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 ...

According to new research from Rice University, while Edison’s goal was simply to create a longer-lasting electric lamp, the ...
