Light Emitting Diodes Save Energy And Can Now Concentrate Light Precisely Where Needed http://apocadocs.com/s.pl?1210858736
Light-emitting diodes are unbeatable in terms of energy efficiency. A one-watt LED delivers roughly the same optical output as a hundred-watt light bulb. If a high light output is required, however, the tiny light sources are not the preferred means of illumination. A novel optical component is set to change that situation. It directs the light to the exact spot where it is needed. In the case of a desk lamp, for instance, the light can be concentrated in such a way that only a DIN-A4-sized surface in the middle of the table is brightly lit. The LED evenly illuminates the required area, while everything else stays in the dark.

I am LED to believe in this kind of lighting. Watt's slowing us down?
