A power system with light-controlled function and the control method thereof, which power system comprising a light sensor module, a first microprocessor, a wireless transmitter, at least one controlled socket, a wireless receiver and a second microprocessor. Each intersection includes an electrically linear resistive element in series with a voltage breakdown element. The present invention further includes a plurality of carbide buttons affixed to the plurality of notches respectively for cooperating with a plurality of cones during operating conditions to thereby prevent the plurality of cones from dislodging from the lower section and for assisting an operator to bore a substantially uniform hole in a predetermined direction and about the longitudinal axis. The first section is configured to act as an optical guide. Covert feature is revealed either when a decoder device is used with the security device, or when the security device is oriented and viewed in predetermined manner.
