Light changing

I have been doing a lot of reading. One of my books are saying that I should change my lights every 6mo, even if they are working, becuase it emits red wavelengths? I am using 2 blue and 2 actinic lights made by Giesemann.

The spectrum of flourescents gets redder over time. I buy high quality bulbs and change every year. Watch the end of the bulb and when it starts to get a black spot it is getting time to change.
