Can I use an electric menorah?

Here's what you need to know

Most poskim (halachic decisors) hold that an electric Chanukah lamp does not fulfill the mitzvah of Chanukah lights, because the obligation requires an actual flame fed by fuel and a wick, not a bulb. Real oil or wax candles are the standard, though electric ones are used and appreciated in specific situations where open flame isn't possible.

The specific rule is

Use a menorah with wax candles or, better, oil and wicks to fulfill the mitzvah, lighting it in a doorway or window at the start of the night. An electric menorah does not satisfy the obligation and should not be your primary Chanukah lighting if you have any other option.

Background

The mitzvah of ner Chanukah (the Chanukah light) is modeled on the ner tamid (eternal light) of the Temple and, more directly, commemorates the miracle of the oil that burned for eight days. Classical sources describe the mitzvah in terms of oil and wicks, or later, wax candles, both of which involve a fuel source that is visibly consumed by an actual flame. An electric bulb has no wick, no fuel being consumed, and no fire in the halachic sense, so the overwhelming consensus of twentieth and twenty-first century poskim, across Ashkenazi and Sephardi authorities, is that it simply does not count as ner Chanukah no matter how much it looks the part.

That said, electric Chanukah lamps are not treated as forbidden or meaningless. In places where an open flame is not permitted, such as a hospital room, a nursing home, certain dorms, or some workplaces, lighting an electric one is widely encouraged as a way to mark the day and publicize the miracle (pirsumei nisa), even though it does not discharge the actual mitzvah. Someone in that situation should try to have the real obligation fulfilled with a proper menorah at home or through their household, treating the electric one as a supplement rather than a replacement. A synagogue's lights do not fulfill an individual's obligation.

A related and separate custom, common among some families, is to place an additional display in a window facing the street purely for public display, while the actual mitzvah is fulfilled with a separate wax or oil menorah lit indoors with the blessings. Some of those window displays use electric lights precisely because they are meant only as a visual advertisement of the miracle, not as the halachic act itself, so the concerns about fuel and wick don't apply to that display in the same way.

If your only realistic option, for safety, housing rules, or health reasons, is an electric Chanukah lamp, this is a good question for your own rabbi, since there can be room-specific or personal factors that affect what's practical for you.
