Offered is a quality General Radio Variac that is mounted in a heavy gauge Panel box that has a hinged cover. To test the Variac's operation I used a lead light to dim the bulb via the rotating dial on the front from low light to bright light, it works smoothly. I also tested with a large 1/2" drill, it will adjust the speed of the motor.
