Please Enlighten Us – Q. A husband travelling in an essential trip and away from home and a Jewish community for Shabbos, since he can not light candles in the hotel, he relays on his wife doing it at home. He just lights the room the electric lights that he needs for the night and day, without a brocho. He is davening and eating in his room.
How about if they are at different time zones, and she is going to light hours after or even before he already accepted Shabbos, what should he then do?
A. Shulchan Aruch (O.H. 263: 2-3) rules that a man, even though he is also ordained in the lighting of Shabbos candles, he can rely on the lighting of his wife at home, even if he is not there.
Piskei Teshuvos (263: 23) rules that the same applies even in different time zones. Yet the husband should maintain enough electric light in his room to be safe and comfortable, even if he can’t make a brocho on them.
