Or, am I just totally off in my thinking here?
You are confusing power in with power out, they are different because the module is not 100% efficient.
The important thing is what the regulator is supplying the LED and the efficiency of the regulator.
If it's
drawing 0.4A @ 12v then yes, the power consumption is 4.8W.
If it's
supplying 750mA @ about 3.5v the power consumed will be 2.6W.
All of this is conjecture, I'm simply suggesting that checking the efficiency of the module throughout it's input range could yield better results - IF the amount of power used by the light is of concern to you.
