Pc Lights

[kclester]

How often should the lights be changed in a pc lighting system.........and how can you tell when the bulbs are bad ?

The general rule is to change them every 6-8 months. I changed mine every 6months until I upgraded my lights. Now my corals, my wallet and myself are much happier

i am getting rid of my pc lighting right now and going to MH, but i would change mine every 4 or so months because i could see a visual change in how blue the actinics were, probably wasn't necessary lol but it made me feel better
