So I have an orbit 48" 8x54 wat fixture and two of the actinics flicker continuously through the whole day. What should I look at?

Also since i'm on the subject, where can you get replacement moonlights for this specific fixture. Oh and where is the cheapest place to find T-5 bulbs? And one more (I'm a noob to T-5) what is the lifespan of t-5 bulbs?

thanks
Josh

swap known good bulbs with the two bulbs that flicker. chances are that one of the two bulbs that flicker is bad and because the ballast work two bulbs at a time the symptoms will be shown on two bulbs. if the flicker changes to two different bulbs then you have a bad bulb in the set.
