Buzzing with the ZooMed Powersun H.I.D. Bulb

I just bought a new ZooMed Powersun H.I.D. bulb for my tortoise table after reading some good things about it for both UVB and heating. However, when I plugged it in it makes an odd buzzing noise. My other bulbs never made these kinds of noises. Is this normal? Has anyone else with this bulb experienced the same thing?
