[Tim] recently found himself tinkering with a cheap string of LEDs. Far from an advanced, IC-controlled addressable set, these were merely a string with LEDs of four colors that could be switched on ...

SemiLEDs is sampling white light LEDs using a proprietary phosphor technology, which it says delivers “a highly uniform phosphor coating across the emitter surface, greatly increasing colour precision ...
