I suggest that you select long lasting Shabbat candles that can burn for a few hours, and light them with a meaningful ceremony at the correct time, i.e. at least 18 minutes before sunset. When your husband arrives home, together you can inaugurate the Shabbat holiness, perhaps meditate on the Shabbat lights, and then sing Shalom Aleichem, Kiddush and the other Shabbat rituals.
Lighting candles before sunset is a statement that we are putting a stop to the bustling weekday activities by entering a sanctified space of "no work" The Torah states, You shall not light fire in all your dwelling places on the day of the Shabbat (Exodus 35,3). Of all the 39 prohibitions of "melacha", work, this is the only one listed in the Torah explicitly.
Halachically, two distinct facets are essential to the Shabbat candles – the act of lighting and the enjoyment ofthe light. The first is Shabbat in actu, an actual lighting to delineate the entry of the Shabbat. This is implied in the commandment of Shamor as recorded in the Decalogue, Deuteronomy 5, 12-15: Shamor - "Observe the Shabbat day to keep it holy. Six days shall you work and do all your tasks. But the seventh day is a Shabbat unto the Lord your God. You shall do no manner of work".
However, there is also a command of Zakhor, stipulated in Exodus 20, 8-11, Zakhor – Remember the Shabbat. This implies the positive commandment of remembering the historical Shabbat of Creation and Revelation and is expressed verbally in Kiddush[1]
The custom of lighting two candles was instituted by Safed Kabbalists in the 16th century to represent these two distinct, yet complementary, elements of the Shabbat experience. Shamor entails observing the Shabbat by refraining from "work" such as lighting fires. This is symbolized in the kindling before sunset. Whereas, Zakhor ensures a proactive energy of the mitzvot of Shabbat, oneg Shabbat, expressing joy, enhancing our inner light, remembering our spirituality. Safed Kabbalists placed Shamor before Zakhor. Thus we sing in the hymn of Lecha Dodi, Shamor veZachor. One needs to first receive (lekabel as in the word kabbalah) the Divine Effulgence, and only afterwards, become active in the mode of Zakhor.
In sum, in reciting the blessing before the mitzvah of lighting the candles, you announce "Shamor", your readiness to receive the tranquility and illumination created through the Shabbat. Then, when your husband joins you, together you can create Zakhor, remembering the spiritual light symbolized in the candles creating both shalom bayit (harmony in the home) and oneg Shabbat (Sabbath joy).
May the joy of Shabbat lead you together to celebrate a harmonious Shabbat filled with Light of both Shamor and Zakhor.
[1] The Biblical commentator, Nahmanides, notes on this verse in Exodus 20, 8, that each term has its own realm of connotations. Zakhor refers to Love and is expressed in positive commandments such as remembering Shabbat by reciting Kiddush. Shamor refers to Awe and appears in negative commandments such as refraining from work (see also Maimonides, Laws of Shabbat, 29, 1).
