Which is more efficient?

Which is the better way or is there a difference?

Most trailers now days have a 12volt battery which is used to run lights, water pump, etc… We keep the 12volt battery charged by using a converter to change 110vAC power to 12vDC, which I’m fine with that.

The question I have is this:

If I were to install an “inverter” to run 110vAC lights in my trailer (say 40watt bulbs) vs. using 12voltvDC lights would it drain more power from the battery?

Which one is a more efficient use of power as a whole?

I understand you loose a little through the “conversion” process either way and will also depend on how efficient the “conversion” process is as well (higher dollar units vs low dollar units) converting/inverting the power.
