    Ok, hey everyone:thumbup:

    Now I have a few T8 40w ballasts laying around and I want to use some on a small tank I am working on. I want to know if it's possible to just change the connections on the ballast from t8 to T5 connections. The light's I'll be using would be of lower wattage as the 40 watt. Is this possible?

    It probably would work, the bulbs definitely wouldn't run at their optimum, but if you're desperate for light then I guess you could. T5's are built and designed to be run off electronic ballasts, whereas T8's use mostly magnetic ballasts.

    How much lower than 40w are the bulbs?

    It would most likely be 24 watt lights, I have both 30 watt and 40 watt ballasts, would it make that big of a difference?

    Personally I wouldn't go more than 10 watts difference, I am running two 39w T5's on a dual 49w ballast, but they are all T5's and all electronic ballasts, I don't know much about electrickery and magnetic ballasts, perhaps one of the electrical guys can offer more help.
