Embodiments of the present invention relate to an LED light fixture that linearly arranges a plurality of LEDs within a housing such that each LED has a respective collimator. The output from the collimators is directed to a diffuser that shapes the light provided by the fixture so that a desired viewing angle is achieved. More particularly, the LEDs are located on a first circuit board and the driver chips for the LEDs are located on a second circuit board which sandwich a heat sink.
