Maybe we should move some of this thread to another forum because it is getting away from the original post. I would like to add that I have had the feeling for some time that we reefers are playing into the hands of manufacturers and resellers of bulbs. On the basis of daylight in the tropics being 6500K, I have long felt that people are heading in the wrong direction when they discard bulbs after a few months because they feel that the color has shifted. I have a horrible feeling people are throwing out perfectly good bulbs. I myself am still using TWO year old 9325K PC bulbs. The light is still bright, and the color is fine. I have found the same with a 5500K MH bulb which is more than a year old. I am looking forward to some more well documented discussion on this, but for now I will continue to use old wrong color bulbs. :D
