    Hey guys could anyone help with this. I have a Tetra 60l tank one off those complete packs it has a 15w tube. In the cover holding the ballast states 15w max to be used but the ballast itself has T5-11-21w-02-60l printed on it.What does this mean?Thanks

    Ballast usually have a range. Like 20-24W etc.

    So you can put a bigger tube in there if it would fit.
