Do extension cords reduce light output?

I need to route power from another room and can't cut holes into the walls (I'm in an apartment). This will require about 30-40 feet of extension cords to my lights. Is this going to cause a substantial drop in the lumen output of the lights?

not change at all. but you need to make sure you buy cords that are rated for the amperage of your lights, plus a safety factor.
