Can you lower the wattage of the lamp? This is certainly possible with a Durst. You don't say whether this exposure includes under/over the lens filters or dialling in the appropriate Y&M dichroic head filtration.

If you printed unfiltered and the neg's contrast was right for grade 2 then of course the print will look right but will look equally good and at a longer exposure if you dial-in Y&M or place a grade 2 filter under/over the lens.
