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 ...
In a new twist on a 123-year-old idea, scientists at Sandia National Laboratories say they have developed a way to greatly boost the energy efficiency of the commonly used incandescent light bulb.
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 ...
