MH light buzz

Constantin · 04/27/2009, 07:29 AM

I am setting up a new system with 3x400w SE XM 10k powered by PFO HQI ballasts. One singe and one dual ballast.
I purchased the ballasts used, but all the bulbs are new, when I first set up the lights, there was no problem, however, a few hours later, there is buzz coming from just one of the bulbs - the one powered by the single ballast, what does that indicate? when testing out the bulbs with ballasts, I did not get the buzz, any idea?

Help is greatly appreciated!
Thanks!

Metal Halides buzz. Nature of the beast. Not very loud mind you, but they will buzz some.

they dont buzz normally, i am talking about the actual light, not the ballast... the buzz i was talking about was VERY loud, however it seems to have gone away now, but i want to know what it was, because it still sometimes comes back, but on just one of the lights

I have the same problem w/ my 150w MH. Before I replaced the light, there was no buzz, but now there is and it too buzzes on and off. And the buzz also comes from the light and not the ballast.

I have the same situation when I use the bulb with the small black initiation inside. And the buzz sound is on and off.
