well....i've read Scott's responses in the thread below
" an anology of electrical power transfer" a number of times.
i'm starting to realize that a lot of our trade is somewhat programed, spoon fed, or simply given the ten cent tour of theory.
i suppose we need not major in the physics of electricty to do our trade, but it certainly evokes more thought to have a grasp on such things during any given installation.
i can only answer a Q with a Q here.
if energy can't be destroyed, and a light fixtures byproduct is heat, would the tranfer to heat be "loosing" electrons?
Does a more efficent light give more electrons to light that to heat?
If we hook up a mile of wire to your battery, we will see a difference at either end, all due to R factor?
