A total of 300 units were used along sidewalks and roadways on the old campus, which includes a wooded area. After the retrofit, we had the same number of fixtures, but twice the level of light. Illumination levels are 1.5 to 2 footcandles. Wiggins added that another advantage of the RSL-350 fixtures is ease of maintenance. Ballasts in the units can be removed and replaced at the site, with repairs later made in the shop , which reduces the amount of time required on top of a ladder.
Maintenance generally keeps two extra ballast kits on hand to use as necessary.
Although the Arlington units appear different on the outside, they have the same ballasts and lens as the RSL-350, making the parts interchangeable. The units were mounted on existing cast iron poles. Both the RSL-350 and the Arlington fixtures have a colonial look, so they fit well into the historic campus setting. The units have significantly increased the lighting on the walkways, which has eliminated any further requests for additional fixtures. About 98 percent of the fixtures are controlled by photocells, with the remainder on time clocks.
