cool. I have also heard about this new wireless power where you won't even have to plug stuff in anymore!
sounds good, now lets hope they can match the specturm a bit better than that of halogen.

Sounds shit hot, but I'm strictly no interest until I see a general price tag of course.
LED tech looks like the future anyway.

Neah,I ain't gonna start short stroking after that.
Sulphur plasma despite it's magnetrons and microwaves is the way forward.
It is veritably the more light less heat generation of lights.

The benefits are obvious: The diodes are extremely small and consume little energy because they efficiently convert electricity into light. The Ostar Lighting LED, for example, produces 75 lumens per watt at 350 milli-amperes of operating current — much more than an incandescent lamp, which only converts a fraction of the electricity supplied into light, with the rest lost as heat energy. In addition, LEDs contain no lead or mercury, which makes them very environmentally friendly. They also last around ten times longer than halogen lamps and 50 times longer than incandescent lamps, thereby helping to significantly reduce maintenance costs.
A shame about the hype. 75 lumens per watt is
still mostly heat.
The red version may be interesting though ....
For those of us wanting a lot of light, I suspect HID technology is safe for a bit.
I'll think about changing when I see new kinds of streetlamp, and / or commercial growers switching.

The Ostar Lighting LED, which will be launched on the market this summer, can provide sufficient light for a desk from a height of two meters, for example. Its small size also enables the creation of completely new lamp shapes.
A lumen (lm) is the unit of measurement for the amount of light emitted by a light source. A 60-watt light bulb emits 730 lm, while a 50-watt halogen lamp has an output of approximately 900 lm. To achieve the 1,000 lm output for the tiny Ostar Lighting LED, the experts at Siemens’ Osram subsidiary employed a sophisticated system for high chip-packing density, whereby the researchers managed to integrate six high-performance LED lighting chips into the unit’s small housing. Each chip has an area of only one square millimeter, which makes for very concentrated overall luminosity.
Different types of LEDs are used today in various areas, for example as background lighting in cell phone displays, as well as in car turn-signal lights, brake lights, and daytime running lights. The benefits are obvious: The diodes are extremely small and consume little energy because they efficiently convert electricity into light. The Ostar Lighting LED, for example, produces 75 lumens per watt at 350 milli-amperes of operating current — much more than an incandescent lamp, which only converts a fraction of the electricity supplied into light, with the rest lost as heat energy. In addition, LEDs contain no lead or mercury, which makes them very environmentally friendly. They also last around ten times longer than halogen lamps and 50 times longer than incandescent lamps, thereby helping to significantly reduce maintenance costs.
For many years, however, LEDs were unsuited for room lighting applications because they weren’t bright enough. The Ostar Lighting LED marks a further step toward suitability for such applications. Osram has already supplied a Migros supermarket in the Swiss canton of St. Gallen with 18,000 Golden Dragon LEDs, which have a lower output than the Ostar Lighting units. These LEDs emit neither UV rays nor heat, which means they have virtually no negative impact on delicate grocery items such as milk, meat, fruit and vegetables.
