I can certainly help with T8 lighting for the tank you mention, but bear in mind there is also LED and this I have not tried. LED is making great strides these days, it is still a very new concept, and if one knows what they are getting, it can provide good light. But it can also be a failure...and it is very expensive compared to T8.
I use T8 over my tanks that have fluorescent tubes. The "T" refers to the diameter of the tube in 8ths of an inch, so a T8 is 8/8 or 1 inch diameter; a T5 would be 5/8, etc. But these are not interchangeable, so the fixture has to be made for T8 or T5. The older T12, which was the original fluorescent tube, is being phased out as the T8 and T5 are more energy efficient, less damaging to the environment, etc.
I have a 5-foot 115g tank which is close to yours, only 6 inches deeper. I use two T8 tubes and you can see the plant growth in the attached photo. This is what I would go with, two 48-inch T8 tubes. There are several manufacturers of these, check fish stores or online suppliers (probably will be less expensive online). If you're gifted carpentry-wise, you can make a hood with a "shop tube" fixture.
As for the tubes themselves, you want at least one to be from 6000K to 7000K. "K" refers to Kelvin, the colour temperature of light. Scientific studies have shown that aquarium plants respond best to this light. The second tube can be the same, or it can be warmer or cooler. These terms refer to the white tone, warmer having more red and cooler having more blue. I won't comment further on this now, but we can pursue it later. I use tubes with a 6500K or 6700K rating, these are shown in the photo. In your case, for low and moderate light plants (which is what you see in the photo), you can use the less expensive tubes made by GE, Sylvania or Phillips; all three make a "Daylight" with 6500K, and I use them.
