Chapter 8. Candle Lighting on the Seventh Day of Pesach

It is a mitzvah to light Yom Tov candles [1] [and one recites the blessing “lehadlik ner shel Yom Tov,” but does not recite the blessing “Shehecheyanu”]. Some have the custom to light them on the eve of Yom Tov, while others have the custom to light them on Yom Tov close to the festive meal; one who has no established custom should light on the eve of Yom Tov [2] .
