In the News Yes, actually. The old-school, inefficient, heat-generating incandescent bulbs are all but history, CFL (compact florescent) bulbs taking the pedestal what with how relatively inexpensive and efficient they are when it comes to both electricity consumption and overhead cost. However, even these may have a short-lived supremacy as British scientists developed a new way of "growing" the material needed for LEDs on silicon instead of sapphire wafers, which was the original and somewhat expensive way of doing it. Because of this, household-grade lights of LED nature can be produced for under $5.00 and last up to sixty years. LEDs are three times more efficient than CFLs, last substantially longer, and contain no mercury, so they're even more environmentally friendly. These wonder-bulbs are supposed to be available to consumers within two years. It is estimated that if these new bulbs were to be installed in every home and office, it would cut electricity used on lighting by 75%. I'll take twenty of those, please.

Actually is isn't so easiy. If the peaks in waveform, are filtered, as you suggest, that would also take away from the perceived brightess. This in turn would require more LED's and more power. In addition filters can not fix the dips in the waveform, therefore, the quality will continue to be subpar to non-LED. Diffusers can not completely solve the inherent problems and they can also decrease the brightness.

Again, though, that's relatively easy to solve given the high efficiency of LEDs. You can double the number of LEDs in a given fixture and still come out ahead of CFLs.

Personally, I like the idea of combining a red, green and blue LED into a single fixture, and you can then control the colour that comes out by varying the the levels of RGB.

No, LEDs won't be perfect, but they will be plenty Good Enough.
