L3 is a plug and play fixture and is considered a portable luminaire, which means installation can be done by anyone, with out even a permit. The first fixture has a fifteen-foot cord that just plugs into a 110 volt outlet. The adjacent fixtures just daisy chain one to the other and are secured by a couple of screws into our custom brackets. Up to thirty-four fixtures can be installed on a single cord. It is by far the most flexible system we offer and can easily be incorporated as part of the shelving package in the FF&E.
