So my 3.0 single is perfect minus one thing. The bottom flouros don't want to turn on unless you flip the switch on and off several times. Just wondering if anyone else has ever had this issue? Or if it's as I fear that the ballast is just going bad. Wires are all secure, and I switched the leads for top and bottom on the actual power switch to make sure the switch wasn't going bad. Same thing, top turns right on, bottom doesn't till you toggle on off several times.
