Luxim Plasma Light Bulb
Better Stronger Faster than LED

At 140 lumens/watt, these pill-sized plasma light bulbs by Luxim are a pretty awesome contender for “light of the future”. They are almost 10 times more efficient than traditional incandescent light bulbs, twice as efficient as current high-end LEDs, and they also beat CFLs, most of which are around 50-80 lumens/watt. Only the prototype 300 lumens/watt nanocrystal-coated LEDs can hold a candle to them.
And the light from Luxim’s LIFI bulb is not ugly either: color rendering index (CRI) is 91. Lifetime for a bulb is estimated at 20,000 hours, and a relatively large amount of power can be pumped through them, allowing a tiny bulb to produce 30,000+ lumens (not something LEDs can do).
An RF (radio-frequency) signal is generated by the solid-state power amplifier and is guided into an electric field about the bulb. The high concentration of energy in the electric field vaporizes the contents of the bulb to a plasma state at the bulb’s center; this controlled plasma generates an intense source of light.
Luxim seems to want to use them in projectors, but since even a tiny light bulb can produce as much light as a street lamp, sky seems to be the limit if cost can be brought down.

New technology is already challenging high intensity LEDs. Luxim plasma is hot and thick, Edenpark microplasma is cool and flat, even bendable. The Luxim is planned for street lighting because of safety issues one would suspect. The Edenpark flat panels seem more retail, office and home friendly.
