OVER SHABBAT CANDLES
Lighting Shabbat candles on Friday as evening approaches delineates the beginning of Shabbat. Tradition teaches us that we are partners with God. Candle lighting is a sacred deed which allows us to symbolically participate in the act of creation: "Let there be light." Traditionally, two candles are lit, representing the two times that the fourth Commandment is cited in the Torah: "Remember Zachor" (Ex. 20:8)/Observe Shamor" (Dt. 5:12) the Sabbath Day."
Shabbat candles serve at least two purposes: (shalom bayit -- harmony in the home), for they provide light and a "candle light" atmosphere for the Friday night meal, and (oneg Shabbat -- the joy of Shabbat), as they symbolize the light and gladness that Shabbat provides for us. In order to fulfill both purposes, the candles should be lit at the place where the meal will be eaten.
To prepare for candle lighting, find out from your synagogue bulletin the correct candle-lighting time or obtain a calendar with Jewish information from a local organization. Candles are lit between a half hour and 15 minutes before sunset with many authorities holding that the proper time is at least 18 minutes before. Choose a place for the candles to stay throughout Shabbat. Set your candles in the candlesticks and have a match and matchbook set beside them. Finally, at candle-lighting time, assemble the family.
The order for lighting candles at the beginning of Shabbat is unique. Normally a brakhah is said immediately before doing a mitzvah, fulfilling a commandment, and the mitzvah follows without interruption after the brakhah. Since Shabbat starts once we say the brakhah, we cannot light the candles after saying the brakhah. We solve this problem by performing this mitzvah in the following order:

Barukh atah Adonai E1oheinu, melekh ha'olam, asher kid'shanu b'mitzvotav v'tzivanu l'hadlik ner shel Shabbat.
Praised are You, Adonai our God, Who rules the universe, instilling in us the holiness of mitzvot by commanding us to kindle the light of Shabbat.
