WeatherproofWeatherproof ballasts are designed for remote mounting outdoors for all weather conditions. Weatherproof ballasts are often placed inside a pole base but weatherproof ballasts are not water-submersible. The mount must have nipple down and a drip loop for the wiring. This ballast, capacitor and ignitor assembly is protected with an aluminum cover, gasketed and bolted to the heat sink base. There are many applications including billboards, road and sign lighting as well as outdoor sports facilities.
