We light the Chanukah Menorah at home before lighting the Shabbos
candles. (One should recite Mincha before lighting the Chanukah lights.
However, one must be careful not to delay the welcoming of Shabbos
because of this. One may not light neither Chanukah nor Shabbos lights,
earlier than Plag HaMincha – one and one-quarter proportionate hours
before sunset, (a proportionate hour is one-twelfth of the daylight
period). One must be careful to use enough oil (or light a large enough
candle) that will remain lit until thirty minutes after the appearance
of the stars. .
