2x40 = 80 watts 80 watts x 6 hrs= 480 or a little less than half a kilowatt hour. Depending on electric rates in your area, that'll cost around 7 cents.

A lot more than two LED bulbs with a higher lumen output.

That would depend on the hourly kilowatt rate in you particular jurisdiction. Such a rate cost is not universal.
