Abstract

A security lighting system includes a transformer for transforming high voltage current to low voltage current, and a wiring run having electrically conductive wiring for connecting a plurality of security lights to the transformer. Each security light includes a light module having a low voltage LED light, a hat covering the LED light, and a junction box coupled with the light module. The junction box has an interior compartment containing electrical components including a microprocessor connected with the LED light for controlling operation of the LED light, whereby the electrical components within the junction box are electrically connected with the wiring run. A clamping assembly is coupled with the junction box for securing the security light to a fixed element. Each security light includes a light module having the LED light and the hat overlies the LED light to block the escape of direct light from the light module while allowing reflected light to escape from the light module.
