A folding ballast has a ballast housing having an elongated shape. A first socket arm is mounted to the ballast housing at a first socket arm joint, and the first socket arm has a first closed position parallel to the ballast. The first socket arm has a first open position perpendicular to the ballast. A second socket arm is mounted to the ballast housing at a second socket arm joint, and the second socket arm has a second closed position parallel to the ballast. The second socket arm has a second open position perpendicular to the ballast. A first socket is mounted to the first socket arm, and the first socket is electrically connected to the ballast housing. A second socket is mounted to the second socket arm, and the second socket is electrically connected to the ballast housing.
