## Abstract

An LED lighting device is disclosed. The LED lighting device includes an LED circuit having at least two LEDs that are mounted on a substrate and separated from each other by a distance of 3 millimeters or less. At least one of the at least two LEDs includes a different phosphor coating than that of at least one other LED of the at least two LEDs. The LED lighting device also includes a switch selectable by an end user to enable a change in a color of light emitted from the LED lighting device by causing one of at least a change in brightness or turning ‘on’ or ‘off’ the at least one LED with the different phosphor coating of the at least two LEDs in the LED circuit. The substrate and the switch are integrated within the LED lighting device.
