A lower LED light source is mounted in the lower light source housing to generate downlight. An upper LED light source is mounted in the upper LED light source housing and remote from an outer circumferential light transmitting outer side area of the upper light source housing and from which is emitted side light illumination. An LED power supply and light control circuit mounted in the LED light fixture and adapted for connection to a power source. The LED light power supply and control circuit has a dimming circuit and a lower and upper driver current supply circuit. A switch is operative to connect driver current to the upper LED light source when actuated to an “on” position and to disconnect driver current to the upper LED light source when in a normal “off” position. The switch is operative for engagement to its “on” position when desirable to provide drive current to the upper light source and illumination from both the lower and upper LED light sources of the LED light fixture. Various embodiments of the LED light fixture is described. ## Claims ### Claim 1 A dual LED light power supply and control circuitry comprising: a dimming circuit, the dimming circuit providing input
