treehugger.com — 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.

This sounds very similar to Metal Halide lamps ( <a class="user" href="http://en.wikipedia.org/wiki/Metal_halide_lamp" rel="nofollow">http://en.wikipedia.org/wiki/Metal_halide_lamp</a> ) except they use RF energy instead of an electric arc.For anyone who wants to buy one, a modern MH lamp can achieve +70 lumens per watt with a lifetime of 12,000 hours while only setting you back $150.

Tacos? Yes.

That the article is a year old?

That's the frequency of the light - not the temp. Normal CFLs are 6000 if you want a white light.

I wouldn't call it a massive amount of RF energy since the whole point of the bulb is low power. Its the same RF that's used for metal halide lights today.

no, K as in light temperature is the theoretical equiv of the color of iron if you brought it to that heat temperature6500 Kelvin iron looks WHITE

With the lumens per watt being directly related to efficiency it shouldn't generate much more heat than a current high end LED if being powered by the same amount of wattage.

Sometime that's the only heat some people have.You should remember that before you declere the heat waste energy.

The website talks about integration with streetlamps, and notes that part of the assembly comes with its own heatsink. They also note the bulb is fit for applications between -40 to +45C. Mind you, these are street lamp bulbs, not replacements for your CFLs at home.
