How long must the Chanukah candles remain lit? Are all grades of olive oil equally acceptable for the Chanukah menorah? Which comes first this Motzei Shabbos, Chanukah lights or Havdalah? Which oils or candles should be used for the Chanukah lights? May I use leftover oil and wicks after Chanukah? I did not return home until after midnight. In my neighborhood, at that hour of the night, the streets are deserted. May I still light Chanukah candles with a bracha?
