Shabbat 21a
שבת כ״א א — ד"ה אָמַר רַב הוּנָא
Shabbat 21a:12
Rav Huna rules that wicks and oils prohibited for lighting on Shabbat are also prohibited for Hanukkah lighting whether on Shabbat or weekdays, because one would be obligated to tend to and relight the lamp if it goes out, creating risk of adjustment on Shabbat; Rava opposes this, saying one may light with such materials on Hanukkah during the week but not on Shabbat, since utilizing Hanukkah light is permitted on weekdays.
אָמַר רַב הוּנָא: פְּתִילוֹת וּשְׁמָנִים שֶׁאָמְרוּ חֲכָמִים אֵין מַדְלִיקִין בָּהֶן בְּשַׁבָּת, אֵין מַדְלִיקִין בָּהֶן בַּחֲנוּכָּה, בֵּין בְּשַׁבָּת בֵּין בַּחוֹל. אָמַר רָבָא: מַאי טַעְמָא דְּרַב הוּנָא? — קָסָבַר: כָּבְתָה זָקוּק לָהּ, וּמוּתָּר לְהִשְׁתַּמֵּשׁ לְאוֹרָהּ. וְרַב חִסְדָּא אָמַר: מַדְלִיקִין בָּהֶן בַּחוֹל, אֲבָל לֹא בְּשַׁבָּת. קָסָבַר: כָּבְתָה
Rav Huna said: Those wicks and oils with which the Sages said that one may not light the lamp on Shabbat, one may not light the lamp with them on Hanukkah either; both when it falls on Shabbat and when it falls during the week. Rava said: What is the reason for Rav Huna’s statement? He holds that if the Hanukkah light becomes extinguished, even though one lit it properly, one is bound to attend to it and relight it so that it will burn properly. Therefore, one must ensure that the wick burns properly from the outset. And utilizing the light of the Hanukkah lamp is permitted during the week. Consequently, in order to prevent him from inadvertently sinning on Shabbat, he must ensure from the outset that the wick burns well, lest he come to adjust the flame on Shabbat. Those wicks and oils do not burn well at all. And Rav Ḥisda said: Those same oils and wicks with which the Sages prohibited to light on Shabbat, one may light with them on Hanukkah during the week, but not on Shabbat. He holds that if the Hanukkah light is extinguished
