How many lamps are there in the menorah that symbols Judaism?

The symbolic menorah has 7 lamps, but the commonly used Hanukkah menorah (pictured) has nine lamps, and no seven-lamps menorahs are made. This is because the menorah is described in the Bible as the seven-lamp lampstand made of gold, used in the portable sanctuary set up by Moses in the wilderness and later in the Temple in Jerusalem. The Talmud states that it is prohibited to use a seven-lamp menorah outside of the Temple.
