Abstract
An LED lightbulb is disclosed. The LED lightbulb includes at least two sets of LEDs that emit two different color temperature light and that are located on a metal core printed circuit board. The combine intensity outputs of the at least sets of LEDs generate a selected corrected color temperature output. The corrected color temperature output is changed by rotating a diffusing unit with a conductive contact pad that engages contact tracks on color corrected temperature (CCT) buttons and thereby closing a circuit corresponding to a selected corrected color temperature output.
