I am not sure what you man by a Jewish candle; Jews use the same parafin candles that non-Jews use. If you would like to know when Jews burn candles, there are two major ritutal uses for candles in Judaism: a candle is lit for the Sabbath on Friday at sundown, and a series of candles are lit for the menorah during Hanukkah.
Candles are lit during the eight evenings of Hanukkah, and before the onset of the Sabbath and holy days.
There is no such thing as "Hanukkah People". People who celebrate the holiday of Hanukkah are called Jewish people. And there are no Jewish rituals that refer to "long" candles.
