recessed lighting electrical question

hi guys, quick question. i removed 8 flourcesent ballast lights from my kitchen and ran 12/2 wire for recessed. i have 12 of these fixtures i am installing, Shop Utilitech Brushed Nickel with Black Baffle Remodel Recessed Light Kit (Common: 5-in; Actual: 5-in) at Lowes.com (http://www.lowes.com/pd_53794-53058-9203201_4294566032__?productId=1245659&Ntt=utilitech&pl=1¤tURL=%3FNtt%3Dutilitech&facetInfo=) and was wondering if the 15a circuit would be ample to support the wattage with 39w halogen bulbs, the max per housing is 50w i believe. thanks in advance.
