My friends at CAST Lighting have posted a very good blog post about their 24 volt low voltage security lighting system.  This system is geared for commercial use more than residential use.  This is a case study from Pennsylvania State University.

One of the best things about this system is that it is completely portable!  Construction sites that may be around from a month to a few years can really benefit from this type of system which can be moved from one project to the next.
