Q. Kvod Harav; On the night of Tisha Beav if after returning from shul one goes home sits low, continues to recite Kinos or learns the permited Torah parts, does he also have to dim the lights or place some candles?

A. Kovetz Halochos quoting Hagra mentions that there is no need. However, Sefer Haminhagim maintains one should.
Horav Shlomo Miller’s Shlit’a opinion is that one should dim the lights.
