Yes, you will, but not by as much as you think, its not a linear relationship, for example (and using very rough numbers), if you dimmed them to 50% brilliance then they might be consuming 75% of the power they would do on full brilliance.

You could consider re-lamping the fixtures with lower wattage lamps if available (or do as I do, and remove some of the lamps to achieve a comfortable light level)
