I had just posted about changing the T8 out to LEDs It looks like you have the same size garage. In mine I have 6 x 2 tube fixtures. The T8 fluorescent lights were OK but those 6000K 17 watt LEDs kick butt. It may not be the answer your looking for (inexpensive) but its extremely well lit.
I would recommend placing min 4 x 2tube surface mounts but 90 deg. to the fixtures you have now. Or single strip again 90 deg to what you already have.
