China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

The 13W PL tube ballast went bad. The PL tube ballasts is not easy to buy, do not know can not replace the T8 electronic ballast? Can drag 13W PL 22W T8 ballast tube?
Yes, this is no problem. I have used the 40W ballast with a 18W lamp. Maybe some effect on the life of the lamp. T8 does not seem to 22W lamp, 22W ring Lamp only. The best way is to find a similar wattage ballast, the more similar the better. Can not find only T8 18W. In fact, the ballasts are essentially the same, and the diameter of the lamp is not directly related.
