They're under contract, but just as the "make them and we'll keep others from competing with you here", not "you can't sell these elsewhere". The only reason you "can't buy them" is because you wouldn't (or at least people wouldn't). You can't easily tell how good the LED setup is in the bulbs, and price isn't necessarily a good indicator, so you're unlikely to pick the more expensive item.
