Summary:
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 lattice — in effect, a tungsten filament fabricated with an internal crystalline pattern — developed at the Department of Energy’s Sandia National Laboratories has been shown to have potential to transmute the majority of this wasted infrared energy into the frequencies of visible light.

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.
