Buzzing 250 Watt HID Lamp

  1. Hi everyone, I just bought a used Sunlight Supply Sun System II 250 W HID Lamp. When I powered it up for the first time, I noticed that the lamp makes a buzzing sound along with a mechanical sputtering while in operation. The bulb came on and produced consistent light.

    Is this normal? Thanks.
  2. Some used ballasts hum, I guess it's just the luck of the draw when you buy a used one.
  3. How used is it?
    Did they warrentee it at all?
