Lighting control devices, network systems, and methodologies, including methods for providing closed-loop dimming control of such systems, are described. In some examples, disclosed methods and device configurations may include an intelligent photo control configured to accept target dimmed fixture wattage value commands from a user, and provide closed-loop control at the fixture to achieve that target wattage via real-time adjustment of the 0-10V dimming control signal sent to the LED driver. As such, the need for trial-and-error adjustments of the 0-10V analog control voltage, or derivation of dim voltage to fixture wattage response curves in order to achieve a desired fixture wattage level, may be reduced or eliminated.

It is described an outdoor lighting apparatus (1) for fixed installation adapted to be connected to a power grid for being supplied with a grid supply voltage. The apparatus (1) comprises at least one light source (6), a driving circuit (30) of the at least one light source (6), a control and communication circuit (20) adapted to control the driving circuit (30) and adapted to communicate with a remote control device (60).
