1. A light engine for a lighting fixture comprising: a circuit board having a central portion and a peripheral portion;
one or more LEDs disposed on the central portion of the circuit board, the one or more LEDs extending a first distance from the circuit board;
a driver circuit disposed on the peripheral portion of the circuit board, the driver circuit configured to receive an AC input and provide a DC output; and
a filter circuit disposed on the peripheral portion of the circuit board, the filter circuit comprising one or more capacitors, the one or more capacitors extending a second distance from the circuit board,
wherein the second distance is configured to be at least two times greater than the first distance and
wherein the one or more LEDs are positioned on the central portion from the filter circuit disposed on the peripheral portion to eliminate a shadowing effect in light emitted from the one or more LED devices.
