Q. Can one use an electric light for the ‘Shamash’ (central light in the Menorah)?
A. Horav Shlomo Miller’s Shlit’a opinion is that it is preferred to use an oil or candle light for the middle light that is also used for lighting the other lights. It also symbolizes the lights of the Menorah of the Beis Hamikdosh.
