Anybody have devices using RGB LEDs?

When we're referring to RGB LED, we meant red, green AND BLUE dies in one package and accessible interdependent of each other to get full rainbow color range. from green, blue, red all the way to white. Not bi-color LEDs with 3 leads. These have 2 LED dies in one package and when both lit, it is not white. White LEDs is kind of a cheat. No "true white die LED" yet. White LEDs is done two ways by 3 dies lit up in correct ratios to get white or using blue LED die smothered with white phosphors. That is reason you usually see low grade white LED glowing purplish to bluish tinted even "urine-tinted". UGH. For this reason luxeon bin their high wattage white LEDs by grades all the way from bluish, ice cold white to nice soothing warm-white. Quantum dots will come up eventually for white emission by solid state like LED are. This recently discovered last year. Cheers, Wizard
