Q. Can a bochur (unmarried one) light the Shabbos candles before the plag, daven Mincha and then after plag recite the brocho on the candles?

A. Horav Shlomo Miller’s Shlit’a opinion is that one should not light Shabbos candles berfore plag. Rather one should daven an early Mincha in the afternoon and then procede to light Shabbos candles after plag and then go to shul to recite Kabbolas Shabbos.
