A back-up power system for a portable table lamp which accommodates a standard replaceable compact fluorescent bulb that is illuminated from an AC main power source when AC house current is available and is illuminated by a DC to DC converter when AC house current is unavailable, the converter being powered by replaceable low voltage battery located in the base of the lamp and charged by the AC source, with the loss of AC house current being sensed to cause the disconnection of the AC house current source and connection to the low voltage replaceable battery.

A back-up power system which can accommodate a standard electrical device that is operable from an alternating current power source when alternating current is available, but is operable by a direct-current to direct-current converter when alternating current is unavailable, the converter being powered by replaceable low voltage battery charged by the alternating current source, with the loss of alternating current being sensed to cause the disconnection of the alternating current source and connection to the low-voltage replaceable battery.

Apparatus having a threaded shaft with opposed ends containing a pivotal and spring-loaded arm threaded on the shaft, and a member on one of the ends for drilling into a surface and another member on the other end to permit drilling, wherein the drilling member is an extension of the threaded shaft and the extension is removable from the shaft. In a method of the invention for attaching a fixture to a wall or ceiling the steps include (a) using a toggle bolt to drill into the wall or ceiling; and (b) positioning the toggle bolt within the wall or ceiling until a spring-loaded arm associated with the toggle bolt is able to pivot away from the shaft of the toggle bolt to a position preventing the withdrawal of the toggle bolt after it has been drilled into the wall or ceiling.

This is an emergency lighting system that provides an emergency driving voltage to drive at least one lamp when the AC power input to the lamp is detected as absent. A rechargeable battery pack and recharging circuit are contained in a first modular housing, and driving circuitry is contained in a second modular housing. An easily accessible, manually-operable service switch disables the provision of battery power to the driving circuitry (when the switch is in the open state), thereby allowing substantial reduction in installation time and cost. A test switch is included to emulate power failures. A transmitter and receiver mechanism allow a user to remotely disable the provision of battery power to the driving circuitry, thereby offering battery power conservation, if the emeregency lamplight is not needed. Likewise, a photo-sensing mechanism disables the provision of battery power to the driving circuitry, if there is sufficient ambient light.
