Your current lighting (I'm assuming 3 bulbs X 39w each) seems quite reasonable for a low/med light low-tech tank, with a lighting period of say, 8 hrs/day. What type of bulbs ?
Have you not been having success with that ?.
It'll grow many plants well, many more than the few you mentioned.
My 75 gal tank has only 2 X 39w T5 HO bulbs, and my med. planted set-up is doing quite well.
