Claim Text:
1. A light assembly comprising; a first input to receive power from an AC power source; a second input to receive solar power from a solar power source; a controllable power supply having a control input, a power input coupled to the first input, and an output to provide an output voltage having a voltage level controllable based on a control signal received at the control input; a battery input coupled to the output of the controllable power supply, and configured to couple to a battery that is configured to provide battery power; a light circuit coupled to the output of the controllable power supply and configured to provide output light based on power from the AC power source, the solar power and the battery power; a feedback circuit configured to detect a current to the battery and a voltage across the battery and having an output coupled to the control input of the controllable power supply to provide the control signal to the controllable power supply based on at least one of the current to the battery input and the voltage across the battery; and a resistor circuit coupled in series with a plurality of LEDs, the resistor circuit having a first configuration with a first resistance value in AC power mode of operation and a second configuration in battery mode of operation with a second resistance value in battery mode of operation, the first resistance value being less than the second resistance value.
