About two weeks ago I purchased a new 400 watt HPS bulb for my plants now in flowering. I noticed that the bulb has a dark blemish near the base. The bulb still lights up but I am thinking that I have a bad bulb and while it is still under warranty I should return and replaced the bulb. I am also thinking that this blemish on the bulb could be affecting the output or performance of the bulb. Before I go stomping back to return and replace the bulb, should I be concerned about the blemish and the bulb not preforming as it should? Thanks
