Our Rabbis taught:
The mizvah of Hanukah is one candle per household.
For the beautifiers: one candle per person.
For the beautifiers of the beautifiers:
Shammai’s Academy says: “On the first day, light eight; thenceforth, decrease.”
Hillel’s Academy says: “On the first day, light one; thenceforth, increase.”

Its mizvah is from sunset until traffic in the marketplace ceases.

Our Rabbis taught:
It is a mizvah to place the Hanukkah lamp by the door of one’s house on the outside;
if one dwells in an upper chamber, one places it at the window nearest the street.
But in times of danger, it is sufficient to place it on the table.

Rava said: “It is obvious to me [that if one must choose between] the house light and the Hanukah light, a house light is preferable, for peace of the home.
[Between] the house light and sanctification of the day – the house light is preferable, on account of the peace of the home.”
Rava asked: “What about [choosing between] a Hanukah candle and sanctification of the day? Is it that sanctification of the day is preferable, since it occurs with more frequency or, perhaps, the Hanukah candle is preferable on account of publicizing of the miracle?”
After he asked, he then went back and laid it out: “A Hanukah candle is preferable on account of the publicizing of the miracle.”
