Other than Alternanthera and "monorrieri" (which I have never kept), you have low-light to medium-light plants. So, you could save some electricity by only using 2 x 65 watt bulbs. Best guess is that you're pushing around 4 - 4.5 Watts per Gallon right now, even with it 4" raised. I have some of the same plants in a same-size tank and have 2.2 Watts per gallon.
