Can you hear me OK? <a href=" http://www.clusterlosser.nl/blog/?p=order-diflucan-online-uk.pdf ">order diflucan online uk</a> Existing white LEDs are not truly white. White results from combining colors of the entire spectrum, but light from blue, green and red LEDs can be combined to create white light, as is the case with many cell phone displays. Other "white" LEDs use blue LEDs, "down-convert" some of the blue to yellow, and then mix the blue and yellow to produce light that appears white.
