As I interpreted it, potions are doubly bound. The ingredients only 'remember' as much of an affect (light, luck, heat, strength) as was put into them, but they're also constrained by magic. Everything is bound by Magic In, Magic Out. Hence the talk of potions requiring magical ingredients.

So, I guess I missed something. What was the magical ingredient in Harry's potion of light?
