Abstract
Methods and apparatus for a security light having a remote photovoltaic module is set forth. The security light includes a primary rechargeable battery connected to the remote photovoltaic module while also having a backup battery system to be utilized when the rechargeable batteries condition require recharge. The security lighting unit functions as a security light to provide variable wide area illumination based upon environmental and battery conditions and also which power supply is optionally connected to the load, the load being the illumination sources and the various supportive electronics. The system further includes a controller which can not only operationally selects either the rechargeable batteries or backup batteries but also can monitor battery condition to preserve battery life. In operation, the security light may include a variable battery power supply for ease of installation.
