PhysicsWeb - Nanobulbs make their debut

"...physicists in China have now made a light bulb in which the conventional tungsten filament is replaced by carbon nanotubes. The new design has several advantages over traditional light bulbs and could be available in less than five years (J Wei et al. 2004 Appl. Phys. Lett. 84 4869)."
Finally a real, practical use for carbon nanotubes. These lightbulbs burn brighter with lower applied voltage and will probably last longer.
