What advantages does a suspended lighting system have?
What will be an ideal response?
A lighting system composed of fixed outlets and a fixed conduit system is not easily adaptable to changing requirements. On the other hand, a system of luminaires suspended from a trolley system can be readily shifted from one location to another as desired. It is not necessary to take down or replace heavy conduit systems as would be required to change a fixed lighting outlet system. If extensive alterations or a major plant changeover requires the removal of the lighting trolley duct, the duct sections are completely reusable.
