This report provides additional exterior lighting information in a format that will assist U.S. Army Corps of Engineers (USACE) operations managers, navigation lock and dam administrators, and design engineers to provide better, more economical light emitting diode (LED) lighting for navigation locks and dams. This report is also intended to be used by navigation lock and dam Lockmasters and Operations Project Managers (OPMS) as tools to create sustainability work packages that compete for project funding differently than Operation & Maintenance (O&M) project funding.
It identifies LED light fixtures in use and reports lessons learned from existing LED light fixtures and LED lamps that have been installed at USACE navigation locks and dams. This report compares illumination values of LED light fixtures to high-pressure sodium (HPS) light fixtures installed at navigation locks using computer software models as well as field-measured illumination values. Finally, this report compares energy consumption and life-cycle cost estimates between LED and HPS light fixtures.
