Hilchos Chanukkah / reciting the blessings – 30

1. The blessings for kindling the lights should be recited with utmost concentration and joy, for [the rarer] the mitzvah [the more it] is cherished, and Chanukkah only comes once a year (Kaf HaChaim676:8).

2. Holy angels come to a person’s home at the time of lighting. In their honor, when lighting the menorah, the person should don his upper garment (i.e., jacket), as he would do when going to the beis hakeneses [synagogue] (ibid.).
