How much power is consumed by resistors is dependent upon the layout of the circuit.
However LEDs are still MUCH more efficient at turning power used into usable light. That light output is also very controlled.
I'm currently working on replacing a 310 lumen incandescent bulb that consumes 18 watts with a 430 lumen high power LED that consumes only 8.5 watts (resistor included).
The more significant difference between the two is service life.

Using half the power to make more light is quite significant.. I wouldn't play it off, personally.
Thank you for clarifying.. I planned on making LED lights for home use. (Screw them in just like the fluorescent replacements.)
