new lights...

Hi,
I have a new-to-me light fixture, which works great!
I just bought new bulbs and put them in, now the unit is "buzzing" every once in a while (like it's vibrating) - is this normal?

Is it the lights buzzing or the ballast?

I dont know.
The fixture is a TEK 6 bulb - that's all I know about it.
it was not buzzing with the original lights that were in it when I bought it.

Hmm. Usually when a ballest is getting towards the end of it's life it will buzz. Maybe the new bulbs are making the ballest work harder?? I'm not sure though.
