When to light the Hanukkah lights

Hanukkah lights should burn for at least one half hour after it gets dark. The standard candles sold for Hanukkah burn for half an hour, so on most days this requirement can be met by lighting the candles when it is dark out. Friday night presents a problem, however. Candles must be lit before the start of Shabbat and inexpensive Hanukkah candles do not burn long enough to meet the requirement. A simple solution is to use "tea lights" or Shabbat candles, arranging them in a straight line and setting the shammus candle apart and above the rest.
