I've just recently got into using shoplight fixtures for CP lighting, so it's probably been about two months since I bought all the fixtures and the tubes. I've already noticed that some of my cool white tubes have lost some of their brightness. Is this normal?
I remember reading somewhere that it's wise to replace flourescent tubes roughly once every three months since they lose lumens very quickly. How often do you all replace your tubes?
