All three Jewish communities in India used Hanukkah lamps with backplates composed of three metal strips arranged in a triangular form. Those on the Cochini lamps have curvilinear shapes, as represented here, while those on Baghdadi lamps are straight with a scalloped edge. Sockets across the bottom of this lamp would have held long curved metal brackets, now missing, in which glass cups for the oil were placed. This method of holding the oil containers was adopted by the Cochini community from the Baghdadi and Bene Israel Jews, and was most likely from Iraq. Cochini oil containers traditionally consisted of an attached row of ovoid metal vessels, or a metal shelf across the bottom of the lamp with holes for glass cups.
