Abstract:
An LED lighting device is disclosed. The example LED lighting device includes at least one LED circuit having at least two LEDs, where an LED of the at least two LEDs is configured to emit a different color temperature of white light than at least one other LED of the at least two LEDs. The example LED lighting device also includes a switch directly connected to the at least one LED circuit and configured to be manually switched by a user to change the color temperature of white light that is emitted from the at least one LED circuit. Switching the switch changes the color temperature of light emitted from the at least one LED circuit by dimming or increasing a brightness of the LED that is configured to emit the different color temperature of white light than the at least one other LED of the at least two LEDs.
