Allusion על שבת 42:11

One should place [the Hanukkah light] above three handsbreadths [from the ground]. It is a mitzvah to place it beneath ten handsbreadths. But if he placed it above ten handsbreadths, he has fulfilled his obligation. However, if he placed it above twenty cubits, he has not fulfilled his obligation. Rem"a: And even if he took it as it is, lit, and placed it below twenty cubits, he has not fulfilled his obligation, because the kindling accomplishes the mitzvah. (Beit Yosef quoting Tosafot)
