A device has an electrical connector, a radiation generator, and a flexible carrier with circuitry that is operatively coupled between the connector and the radiation generator. In response to electrical power received through the connector, the circuitry energizes the radiation generator, and the radiation generator emits radiation. In a different embodiment, a device has an electrical connector, a radiation generator, and a member with circuitry embedded therein. The circuitry is operatively coupled between the connector and the radiation generator. In response to electrical power received through the connector, the circuitry energizes the radiation generator, and the radiation generator emits radiation.
