Do I Need to Light Hanukkah Candles Again After a Communal Lighting?

If I find myself at a large Hanukkah party or a communal gathering where Hanukkah candles are lit, do I still need light when I get home? If I do, is it okay to say the blessing two times? What if I said the blessing at Ma'ariv while leading the service? Does it matter how late I'm getting home?Have a question you'd like answered on Responsa Radio? Email us at responsa@hadar.org.
