How long before...??

How long should you wait before you replace the PC blubs??

it should tell you on the bulb itself of how many hours the bulb will be good for. unfortunetly you have to do the math on when you will have to change them. duration of lighting per day divided by how many hours, or something like light. i think the average is to change every six months or so.

I usually chang my PC bulbs out every 6-8 months. The box will tell you they are good for 12-14 months but you can usually tell that they are going out.
