Ramban and R. Bachye #1: It seems that other candelabras tended to contain additional lamp-holders - either ornamental, or to add light; not so the Menorah in the Mishkan, which contained only the specific lamps that Hashem prescribed.

R. Bachye: They correspond to the upper 'Neiros ha'Ma'arachsh' ? the seven planets. 1
