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 ...

Mimicking Edison’s experimental setup, Eddy attached the light bulb to a 110-volt direct current electricity source. He allowed it to flow for 20 seconds, as bouts of heating longer than that can form ...

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 ...

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 ...

When researchers set out to rebuild Thomas Edison’s 1879 light bulb, they expected a history lesson, not a materials science ...

A microscopic 3-D tungsten photonic crystal lattice (TPCL) developed by Sandia National Laboratories (Albuquerque, NM) has demonstrated the potential to transmute the majority of wasted infrared ...

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 ...

New Delhi: The common yellow bulb of Indian household will soon loose its luster. Modern day LEDs (Light Emitting Diodes) will soon replace them everywhere. This year the production of 100-watt ...

Ottawa's planned ban on incandescent light bulbs will have no impact on Canada's resurgent tungsten mining business, industry players say, because lighting makes up such a small proportion of the ...

Qatar General Electricity & Water Corporation (Kahramaa) on Sunday urged customers to help reduce electricity consumption by replacing tungsten lamps at home and other buildings with energy-saving LED ...
