I am in the middle of changing my 95W coralife VHO actinic 36" light out. I have had it running on my system for 1 year. At this point I am viewing one old one, and one new one. They both look the same to the naked eye. I expected one to look faded. I am having a hard time admitting the 1 yr old lights are done serving their purpose here on earth. Should the old ones fade, should I notice a difference? How much of a difference should I notice?

I helped a buddy change his out, not sure how old it was, but I could see him letting it go longer than the suggested. It was really faded. It felt like we accomplished something because we noticed a drastic difference.

How often should I change VHO Actinic?
