אורח חיים רע״טOrach Chayim 279

Se’if 1א׳

נֵר שֶׁהִדְלִיקוּ בּוֹ בְּאוֹתוֹ שַׁבָּת, אַף עַל פִּי שֶׁכָּבָה, אָסוּר לְטַלְטְלוֹ. וְכֵן מֻתָּר הַשֶּׁמֶן שֶׁבַּנֵּר שֶׁהִדְלִיקוּ בּוֹ בְּאוֹתוֹ שַׁבָּת, אָסוּר לְטַלְטְלוֹ וּלְהִסְתַּפֵּק מִמֶּנּוּ בְּאוֹתוֹ שַׁבָּת.

The Laws Governing Carrying a Lamp on Shabbat. Containing 7 paragraphs: It is forbidden to move a candle that was lit that Shabbos even after it has gone out. The leftover oil in a candle that was lit on that Shabbos is forbidden to move or use that Shabbos as well.

Se’if 2ב׳

נֵר זֶה שֶׁאָמַרְנוּ שֶׁאָסוּר לְטַלְטְלוֹ, אֲפִלּוּ לְצֹרֶךְ גּוּפוֹ וּלְצֹרֶךְ מְקוֹמוֹ אָסוּר; וְיֵשׁ מִי שֶׁהִתִּיר, וְלֹא נִרְאוּ דְּבָרָיו. הַגָּה: וְיֵשׁ אוֹמְרִים דְּמִי שֶׁהוּא אִיסְטְנִיס וְהַנֵּר מָאוּס עָלָיו מֻתָּר לְהוֹצִיאוֹ דְּהָוֵי לְדִידֵיהּ כִּגְרָף שֶׁל רְעִי, וְהַמַּחְמִיר לֹא הִפְסִיד (מָרְדְּכַי רֵישׁ בֵּיצָה).

The candle, which was mentioned as being forbidden to move, is forbidden even when it is needed or its place, and although there is an authority that permitted it, his opinion is not accepted. Rema: Some say that one who is finicky and the lamp disgusts him is permitted to remove it, for it is in his eyes as a night pan. One who is stringent does not lose out. (Mordechai, beginning of Beitzah).

Se’if 3ג׳

לְטַלְטֵל נֵר עַל יְדֵי שֶׁנּוֹתְנִין עָלָיו לֶחֶם בְּשַׁבָּת, אָסוּר. וְאִם נָתַן עָלָיו הַלֶּחֶם מִבְּעוֹד יוֹם, יֵשׁ מִי שֶׁמַּתִּיר לְטַלְטְלוֹ בְּשַׁבָּת עַל יְדֵי לֶחֶם זֶה, וְאֵין לִסְמֹךְ עָלָיו.

It is still forbidden to carry a candle by placing some bread that is permitted to be moved on the lamp while it is still day [on Friday]. There are those who permit to carry it on Shabbat via carrying bread and one should not rely on this.
