eye hortilux super hps 1000 watt bulb harmonic noise?

I am running a 3k set up. All three ballasts are Baddass digital low frequency ballasts. I replaced my original 1000 baddass bulb with the eye hortilux super hps and now there is a very noticeable noise resonating from the bulb. If I turn that light off and keep my others on I hear no noise. Just wondering if this is normal for this bulb or what>?

for what its worth I run the 600 Eye Hortilux super hps and theres no noise outta my bulb (if only I could say the same for the ballast!)
