the power in my house flickers on and off every once in a while(fucking irene) and everytime this happends my mh light goes out and needs 15 min to cool down before i relight it..my question is if my power surges again and my light goes out it will try to reignite with out that cool down time ,the light will just flicker now i have been home everytime the power has surged and turned the light off for the 15 min.how much damage would that cause if i was not home to shut the light off?
