1. An apparatus comprising:

  • a bulb-shaped light-passable body to define, at least in part, an enclosure;

    a light emitting diode (LED) disposed within the enclosure;

    a first power supply interface configured to be coupled to a rechargeable battery in a manner such that the rechargeable battery, when so coupled, is disposed within the enclosure;

    a second power supply interface configured to be coupled to an alternating current (AC) power supply;

    a temperature sensing device configured to be thermally coupled to the rechargeable battery to provide an output proportional to a temperature of the rechargeable battery; and

    a controller disposed within the enclosure and coupled to the LED, the first power supply interface, the second power supply interface, and the temperature sensing device and configured torecharge the rechargeable battery from the AC power supply through the second power supply interface;

    power the LED from the rechargeable battery through the first power supply interface or the AC power supply through the second power supply interface;

    wherein the controller is further configured to recharge the rechargeable battery and/or power the LED based at least in part on the output of the temperature sensing device.
