Specifications include, but are not limited to: Retrofit the airfield edge lighting fixtures for Runways 17L-35R & 17R-35L, Taxiways, and Taxilanes at Henderson Executive Airport. This project will replace the existing edge light fixtures with new Light Emitting Diode (LED) fixtures and will use existing infrastructure (conduits and fixture bases). The existing high mast lighting fixtures will be replaced with new LED lighting fixtures on existing light poles adjacent to the Terminal Ramp. New LED high mast lighting fixtures on new poles will be installed at two (2) locations along the north edge of the Terminal Ramp. In addition to the installation of new LED fixtures, the existing constant current regulators will be replaced to take advantage of the reduced loads due to the installation of the new LED fixtures.
