Solid-state light source lightbulb: Light-emitting-diode (LED) bulbs produce more light with less energy than incandescents, could potentially claim a lamp life much longer than 10 years, and ...

UC Santa Barbara holds several patents for filament-style LED technology. The bulbs have an antique aesthetic but are much more energy efficient than the original Edison bulbs.
