mh problem

[robzilla]

earlier today, came into my fish room and my mh light was off and the ballast was making a ticking noise. i checked the plugs, unplugged it and plugged it back in and it started to work again. and now i came into the room and the light wasnt intense as it normal is. it was a shade of blue, similiar to when it's warming up. the light seems to be surging different spectrums.
any ideas? faulty ballast? the unit was purchased new in feb.

Check to see if the bulb is broken, when my bulb broke it still fired and had the same effects

That happens when mine first turns on. I would see if you can test the balast with another bulb, it might be the balast going.

What light (brand and wattage), and what ballast is it? I.e., electronic, or standard?
