Member CAST Lighting LLC's LED Perimeter Light offers a new low-cost approach to perimeter security. The LED perimeter light is a low-voltage security lighting system comprised of rugged LED fixtures and a reliable power supply. Mounted on fence posts, these lights are simple and quick to install and consume a fraction of the energy of traditional security lighting. They can also be used in any lighting application where long wire runs are required (such as wooded paths and piers).
