That's not a good thing. You should replace your bulb with the proper wattage. Remember you can't use a 400w HPS on a 600w HPS Balast

MH and HPS should be replaced when they are 6 months old depending on how many hours of grow time they have on it. As soon as they get discoloration then its time to change the bulb out.
