Guest guest Posted March 9, 2006 Report Posted March 9, 2006 Hi Ken, I was just checking the efficiency of white LEDs. According to this article from November 2005, the current white LEDs are not much more efficient than the best fluorescent tubes. This would indicate that lighting your house would require at least a few hundred watts. (you thought your friend had said " a few watts " ). http://www.treehugger.com/files/2005/11/white_led_break.php I didn't have time to check on just how safe the light is compared to fluorescent tubes (which are known to be a problem). Both white LEDs and fluorescent tubes use UV to light up phosphors (for producing white light). A CRT produces white light by combining red, green and blue phosphors (take a close look at any white area of your TVs CRT and you will see only these colors). You can't see this on a good computer monitor (the phosphor dots are too small). So, if the light from white LEDs is not healthy, maybe combining the proper shade of red, green and blue LEDs would produce a more healthy white light (probably won't be near as efficient though).

KU> Hi Bil, KU> Most new motor bikes and some cars have red LED arrays, all assembled and ready to go, just requires a 12 volt signal. KU> A friend of mine has used some super powerful clear white LED's in all his housing wiring, while its not as strong as the 100 watt lights, you soon get very use to it and reading fine print books KU> at night is a snak. I think he told me he can turn on all the lights in his home, which is well illuminated, and less than a few watts of power is consumed. KU> Now this is a good way to start looking after our environment.

KU> Speaker outputs can vary from a few volts to over 15 volts.

Arrays of different type LED's can be obtained through most electronic shops, just hook them up to a speaker port from a stereo amplifier and play a CD with frequencies on KU> it or KU> KU> connect the computers sound card to the amplifier and run one of the popular software programs. KU> KU> The LED's wont produce a square wave, you get a fast rise and fall time with a domed top. Sort of inbetween a square wave and a sine wave. KU> Quote
