1. A lighting device comprising:
a driver circuit and a first LED circuit mounted on a printed circuit board, the first LED circuit configured to receive power provided from an output of the driver circuit, the first LED circuit including a plurality of discrete LED packages electrically connected together in series, wherein the first LED circuit is configured to emit a first color temperature of white light when receiving the power from the driver circuit;
a second LED circuit mounted on the printed circuit board, the second LED circuit configured to receive power provided from the output of the driver circuit, the second LED circuit including a plurality of discrete LED packages electrically connected together in series, wherein the second LED circuit is configured to emit a second color temperature of white light when receiving the power from the driver circuit, the second color temperature of white light being different than the first color temperature of white light emitted from the first LED circuit;
a switch configured for user control,
wherein the switch is configured to control a level of the power received by the first LED circuit and the second LED circuit based upon a user-selected position of the switch, and
wherein the first LED circuit and the second LED circuit are configured to change brightness levels of light emitted in response to the user changing the position of the switch;
a bridge rectifier mounted on the printed circuit board, wherein the bridge rectifier is electrically connected to the driver circuit and configured to receive an input voltage from a mains voltage power source, and wherein the driver circuit is configured to receive an output voltage from the bridge rectifier;
a fixture including a lens, wherein the printed circuit board is mounted inside the fixture and covered with the lens;
a first power connection lead electrically connected to a first voltage input on the printed circuit board; and
a second power connection lead electrically connected to a second voltage input on the printed circuit board.
