I wouldn't worry about that. If MH's, yes. I'd still replace your bulbs ASAP though.
Actinic Light I copied this from a WEB-Site
Actinic light promotes the growth of Zoaxanthellae algae, essential for the growth and well-being of all photosynthetic corals and invertebrates (not macro algae). However, Actinic and strong blue spectrum lighting is visibly blue and will definitely need a full spectrum bulb to help offset the color distortion.
If your reef or marine tank appears too blue, balance its visible spectrum with a more intense daylight bulb or add another daylight bulb to the group. 5,000K-6,000K is usually pretty good. However, remember that macro algae can be a problem. Too much "daylight" (with enhanced red spectrum) will promote plant growth, and macro-algae responds similarly. A good rule of thumb is to use one actinic lamp and one or two daylight lamps for each 30 gallons of water.
