Agreed, sir. However, my original post was in disagreement to what you had stated:A light that can be used on both 120 and 240 will use less amperage on 240
"240 uses less power than 120 so that's a plus."
It doesn't use less power. It uses the same. What's happening is the voltage doubles and the current draw halves. Watts = I x V.
