The EFFEX floodlight (Marine option) was the ideal fixture of choice for the Zakim Bunker Hill Bridge because of precise optical control, ease of maintenance with a separate ballast tray, and the marine grade alloy combined with our marine grade finish. These features allow the EFFEX to handle the harshest of climates, and to retain it's great look during many years of operation. This project also incorporated bi-level dimming control to take advantage of additional energy savings.
