CPL3 Generation 3 Series

CPL38, CPL312, CPL316, CPL325


CAST Perimeter® Security Lighting GEN 3 is the world's most sophisticated LED security lighting solution. Winning awards and accolades for it's precision, efficiency and robust security solution. CAST Perimeter® GEN 3 can be combined with your choice of security system to automatically turn on the lights when an intruder approaches or attempts to climb the fence.

We guarantee a seamless integration with your security system results in a total solution. Use the CAST Perimeter® innovative low-voltage LED technology to deliver precise lighting and enhanced camera images at an incredibly affordable price.

The GEN 3 (CPL3) attaches directly to fence posts and can be integrated with 3rd party security systems. Install CPL3 with with our Flash Glare™ option and force intruders out.

The GEN 3 series can have different voltages of 8 Watts (CPL38), 12 Watts (CPL312), 16 Watts (CPL316), and 25 Watts (CPL325). All four options use the same light fixture, so the light will project the same distance (on an 8' fence the light will project 60' on each side of the fence, or 120' one one side), the difference is which driver is installed in the light. For the CPL38 and the CPL312 one LED driver is all that is needed. For the CPL316 and the CPL325 two LED drivers are installed. The difference is the light level produced at the same distance.

As our premier fixture, GEN 3 is loaded with product features that create precise, effective security lighting. It has the widest light distribution at 120' foot diameter and four different lighting levels. It is also built with small details that improve performance such as:

  • Custom stem length available
  • An adjustable knuckle to 22' beam angle adjustment
  • A luminaire shape that limits glare from water run-off
  • A junction box that is quick to connect to the fence and easy to maintain
  • Solid Castings that last to protect the perimeter in the most extreme conditions
  • Simple wire splice and easy maintenance design
  • Easily Field Repairable Electronics

GEN 3 is designed to integrate with existing fence structures and security layers using easy one man mounting brackets, custom stem lengths if required, and easy wiring connections.
